Forcefield Limb Tubes 4.4 5 73 73
Basic knee protection to wear under pants. I bought these to use as knee protection to wear under pants. They fit nice and slim, fantastic air flow and very comfortable. Not much protection other than knee cap. I went down with them on. They certainly helped but i wish there was more coverage. I plan to invest in the Forcefield Grid knee protectors in the future. October 10, 2015
good protection I've got the size large limb tubes for use on my knees. Overall the protection feels quite good. I tested by dropping to the floor on my knees and they took the impact quite well. I've ridden with them both by using the tubes and by putting the pads into the insert pockets on my riding pants. I felt that the tubes tended to slide down a bit. On long trips I've noticed a couple problems. When wearing the tubes under jeans, I felt the tube fabric bunching up behind my knees which became uncomfortable on longer rides. I also start getting knee pain after 4-5 hours of riding. I think this is because my pants press them tight against my knees when riding with legs tucked. The price seems rather high for some elaborately molded foam pads, but there aren't any cheaper alternatives with the same level of protection that I can find. September 6, 2015
Great fit, comfort and protection! I wear these under Kevlar jeans and they're awesome. They don't move around and they don't bunch up behind the knee. 10/10 August 10, 2015
Nice Concept Getting dressed in harmony with the character of retro bikes is not an easy task, if you also care about protection. There are lots of motorcycle garments with various degrees of nostalgic touch in their design but nostalgia and contemporary protection do not mix easily. Very protective garments are also too technical for riders of retro bikes. These limb tubes address to this dilemma quite successfully. Since they can be worn under motorcycle jeans (or any pants w/o knee armor), they are not visible. Therefore, there is no concern on how they look, provided that the pants in question are not particularly tight at the legs. As for how protective they are; they seem to be as protective as invisible armor can be. I would not like to depend on them for racing but even professional racers of a few decades ago would probably prefer them to what was integrated to their racing suits, then. The armor itself is serious stuff and the way it stays put seems to be firm enough. IMHO, they would not twist or slide so easily during a crash. They are more comfortable than I was expecting them to be. I can even forget them during long rides. They remind me of themselves once I am off the bike but this is not an annoyance, provided that I sit down. When I stand upright or walk, their lower edges slightly press on my lower leg bones. I wouldn’t describe this as pain but just as nuisance. In fact, I never felt the need to remove them, even for long hours off the bike, when I knew that I would ride again the same day. I reckon this slight pressure when upright is a small price to pay against the protection they seem to provide during the ride. They are well ventilated. I normally sweat like a pig but under my motorcycle jeans, they didn’t annoy even me. My knees probably would sweat if I had leather pants or chaps on them but in this case, the blame would be on leather. I never put my leg on my bike w/o them since I got them last month and I never will. After about 2000 km (1250 miles) with them, I feel they are comfortable and they seem to be reasonably protective. In my book, they do fit the bill. June 11, 2015
Forcefield Limb Tubes were a great purchase! No Regrets!! I ride a duel sport with these and needed something that stayed in place. I could never get the pads that fit in my riding pants to stay on my knees. But the Forcefield Limb tubes do!!! I have large calves and thighs and I don’t even need the Velcro straps. I just pull the bottom tub just above my calf behind the knee and it never moves. April 27, 2015
Feel good, hidden from view The armor feels like it'll hold up when needed. Fitted well inside of elastic sleeves with velcro at the bottom and top for a secure fit. The armor comes out so you can wash the sleeves. I just threw them into the washer and dryer and they came out alright. I wear them under my riding jeans but if you're wearing skinny jeans they might not fit under. They do dig in and feel a bit uncomfortable standing but once you're riding, or even just sitting down, you don't even notice them. The armor sits just above my knee cap to halfway down my shin. Decent price, solid build, I trust them to protect. March 30, 2015
MTB use I bought this product thinking in MTB as described on Forcefield own webpage. Not recommended at all. It has fabric outside and on first small landing the fabric is gone. It could work okay if used under pants though Large is really large, so better go by measuring your legs before ordering. I use Forcefield back protector for riding my motorcycle and it is just fantastic March 16, 2015
Average kneepads These kneepads are extremely comfortable but they tend to slide downwards for me and I ordered a medium size. Good thing I didn't order the large as they suggested! The velcro straps get sheared pretty easily even after the first use. The kneepads themselves are very flexible and I have tested them by dropping straight to my knees on concrete (didn't feel a thing). Thank goodness they are removeable and washable so I can wash the sleeve portion (as I do get sweaty during long rides). March 13, 2015

RevZilla Store asked: Why did you choose this?
Hernando F: safety and you can use them with any clothes Nov 27, 2015
U P: I have creaky knees and had several surgeries on left one. I have an old (perfectly decent) set of knox knee protectors but they're at least 10 yrs old and straps don't always hold. I want to put on knee protectors under my pants and these will fork for that. Nov 25, 2015
William C: These things are great peace of mind and I am sure they protect well, the problem is taking the time to put them on under your jeans. For guys its not that big of a deal, but my girl can only wear certain types of jeans that are loose. Overall great for safety, but we honestly do no take the time to put them on every time. Oct 5, 2015
JD D: To wear under my Badlands Pro suit. Sep 10, 2015
Chalmer B: Needed something for under my normal clothes, and these look like they'll do the job! Sep 7, 2015
N A: I chose this because it forces the protection to stay in one place. Unlike a jacket or pants, the pads don't move left and right so you know that when you hit the ground (hopefully not) they will be directly over the joints you need them to be over. I recommend going for a small fit because this elastic material inst very tight. I use a size small on the knees and am about 5'7" 170lb slim not skinny. Aug 21, 2015
KENNETH L: better protection Aug 21, 2015
DREW L: Looking for additional protection, the reviews were strong regarding the Limb Tubes. Very happy with decision. Jul 18, 2015
A S: I was looking for knee guars, and found this ones, that can be used under the clothes. I expect to buy pants with protection but in the mean time I think these ones will work fine. Jul 8, 2015
F S: My Forcefield pro pants are great but you have to take your overpants off to put them on/ take them off. These limb tubes are great for commuting to work as I can just slip them on/off at my desk and provide a great level of knee/shin impact protection. Jun 25, 2015
shmuel s: being 5'5" 34w I am yet to have found a pair of riding pant that fit , so I turned to these , my friend swear by them , so I took his recommendation , I also followed the recommended sizing ,ordered a large which is too big, am retuning to get a medium , i wish i read more reviews so i would order it medium to begin with. Jun 19, 2015
Steven L: These were alright never ended up really using them. They slide a around a little too much for my taste. May 27, 2015
Aziz Orhan I: Because I need further protection than my Kevlar reinforced motorcycle jeans can offer but I do not want to use exterior knee armors. The stealth nature of these limb tubes seem to be just the right compromise for me between looks and protection. May 8, 2015
Omar C: good ratings and wanted knee protection that i could wear under my jeans May 5, 2015
Brett R: comfort and safety Mar 20, 2015
Owen C: These fit great. I'm only 5'4" and my proportions make it difficult to purchase pants with pre inserted armor. These are a great solution and they actually fit underneath my jeans. Feb 10, 2015
D A: I need protection for my knees under my pants during office days and the reviews of these are very good. Jan 18, 2015
Neil H: Seems like the best solution to protect knees, while wearing normal pants. Dec 13, 2014
Billy C: Impact protection for knees. Dec 8, 2014
Gordon H: Personal recommendation Nov 30, 2014
Phillip W: I have several pieces of Forcefield armor, know it to be the best for my own applications, and needed to add some armor beneath a favorite jacket. Nov 29, 2014
Kyle M: to Fit under riding jeans Oct 8, 2014
Lamar F: I wanted something low profile to fit under riding jeans. Oct 7, 2014
Michael f: Having no ACL in both knees i needed a bit of help with stability ...LIMB TUBES offered a solution. Sep 21, 2014
David L: I purchased a pair of Rokker Revolution pants, and while they do include armor I wasn't happy with the placement of the knee armor. The armor included with the Rokker's are in perfect position when on the bike in riding position, but would likely slide down and provide shin protection, rather than knee protection, in a get-off. So these seemed to fit the gap in protection I was looking for, as well as the warm weather comfort I wanted also. Aug 2, 2014
Audra A: These are great under work pants and very comfy. Jul 9, 2014
Debra L: I was looking for armor and wanted quality. I wish I had not gotten the tubes, but had gone with the standard armor. Jun 3, 2014
Pete K: your videos sold me on the brand. Your reviews sold me on the item. I was looking for something to wear under jeans Jun 1, 2014
Lukas J: Recommendations on Revzilla all looked pretty good. The fit ensures that they stay in place and offer protection. Apr 21, 2014
Jong L: Should fit without adding bulk Feb 19, 2014
Nelson R: Good low profile look Feb 19, 2014
Stephen E: Crashed on new years day, and the knees haven't been right since. From now on, its kevlar jeans and these tubes for added support. Feb 7, 2014
Prakash S: Seems ideal for wearing under some jeans and not have it poking out for street riding. Feb 3, 2014
L A: I needed knee protection without it being overly bulky when riding on the street or under my suit on the track. Dec 21, 2013
O P: Adequate under Draggin jeans. Dec 10, 2013
Kevin C: don't like to wear full motorcycle pants unless raining, wanted some protection for my knees under my jeans and cargo pants Dec 7, 2013
Justin P: I would prefer if the protectors cupped a bit more and where less rigid. Not particularly comfortable for long rides. Nov 9, 2013
Aristotle P: Fits well over my large calves and thighs. Oct 19, 2013
Fernando L: I'm in love with forcefield products and these limb tubes have worked very well for me. Oct 16, 2013
GREG B: Wear these under my jeans on a commute. they feel good and do not slip. Aug 19, 2013
L A: To add a bit of protection for my knees. I have a previous injury to my knee that I often worry about when riding. Just offers some comfort and protection in the case I go down again. Aug 16, 2013
jonathan j: because its one of the few thin armors that stays flexible in winter Aug 13, 2013

MIKE D: The armor measuring from the center of my knee cap up protects 41/2 in. From the same point of the center of my knee cap down it protects 7 in down my shin. So about half your upper shin is protected. I wear my old Supertech race boots with these under my jeans so they cover the rest. I've tried other protectors that cover more of the shin and found they are uncomfortable, and found myself not wearing them as often as I should have so it's a trade off...comfort over some areas of protection.

Paul D: I wear 36" length jeans and I measure 10.5" from the ankle to the bottom of the protector as being exposed, and 7.5" from the center of the knee cap to the bottom of the protector as being covered.
The limb tubes are slightly longer than other soft-armor brands I own (S&S-TECH) and not as long as hard-armor that comes in track suit.
They are very comfortable and work great under Kevlar jeans.

Stephen L: The limb tubes cover about 5 inches of shin. They are compact enough to wear under regular jeans (not skinny jeans though). I also have the Forcefield Extreme Harness Flite which again is a lower profile armor than my normal riding suit. I also wear the Harness Flite when horseback riding. Forcefield products are well constructed. Aug 16, 2013

A s: I have a set, size medium. They're approximately 13" in length total. They armor measures approximately 10.5" in length. When worn, they cover about 1/3rd to 1/2 of my shin. Essentially they cover the unprotected area left by my race boots Aug 12, 2013

Min Hee K: i am 5'5 & bought the S. i would say my forcefields cover 3/4 of the leg area from my knee down. measuring, there is 5 inches of unshielded shin area between my ankle bone & the bottom of the forcefield. Aug 13, 2013

Esther C asked: Is it possible to wear over your pants if you wear very tight pants? I wear kevlar skinny jeans when riding. Feb 3, 2014
Answer this · Send to friends Good question? Yes (1) No (0)
Min Hee K: I usually wear these under a particular pair of riding pants & they are comfortable. As for wearing over your skinny jeans, sure, it can be done, but perhaps go up a size since you have to slide these babies on & when bending the knee, you have to take into account the slight bunch created by your pants. You don't want to ride around with a rubber band tightness about your knees especially if you ride longer distances. If I were you, I would opt for Dainese or Fox brand knee & shin armor that goes on with a few straps (versus sliding on) for a better fit over jeans. Feb 3, 2014
Reply to Min Hee Good answer? Yes (1) No (0)
Stephen L: Yes. The backside of the tubes are made of very flexible fabric material which should allow you to wear them over close fitting clothing. The tubes are secured by elastic straps fastened with velcro both above and below the knee. Feb 3, 2014
Reply to Stephen Good answer? Yes (0) No (0)
Cy S: It is certainly possible. You would probably find it easier to slide them up the pant legs BEFORE you put the pants on though... and then adjust them into place. Otherwise, the elastic will bunch the pants up at the bottom... Feb 3, 2014

Luis N: Yes!. But I usually wear them (under the pants). It will be somehow difficult to get them over the pants but very possible. Feb 3, 2014

Can these be worn over jeans/pants? Or are these meant to be worn under them?
Jun 24, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
Laurie B: I think trying to hold down the jeans' leg while simultaneously pulling up the limb tube sounds like an exercise in frustration.

These fit very tightly on me and seems like the jeans material, bunched up under the tubes, would become very uncomfortable very quickly, especially if you're sitting instead of standing. And if the tubes aren't tight enough to bunch up the jean fabric, I would wonder how well they'd stay in place in a crash.

I do use these for trials and love them for that.

Kwesi L: They (to me) seem to be made to wear under jeans. It would be very difficult to wear them over jeans as they have a spandex material in the back and you would have to stuff your jeans behind it, ( unless you wear very skinny jeans, which would be breaking a "Man law"). Jun 25, 2015

Lisa W: I wear them under my pants. They are tubes, so i am not sure how easy they'd be to pull up over your pants, tho i guess it is possible if you size up. If you want over the pants armor, maybe something with straps would be more convenient than the tubes Jun 25, 2015

A shopper asked: The sizing chart for the "Limb Tubes" doesn't really help with picking the right size. They come in 3 sizes but the chart just says arms and legs sizes. How can i size my knee area to get the right size.

Floyd: These are "one size fits all," with a lycra/cordura material allowing them to stretch to different size arms and legs. While there are different sizes listed for purchase, the sizing is for different applications, not generally for different people. If using for elbows, buy small; if using for knees, buy large. Medium is for the elbows of large humans and the knees of tiny humans. You'll know who you are if you need to buy mediums. I am 5'11'' 160 and the large works well for me on knee and shin - I can't imagine a medium fitting other than youth or very petite women. Apr 15, 2012

RevZilla: While Forcefield does supply a size chart for the Limb Tubes, we do not find it to be the most accurate reference and prefer to go by the standards of "average", "above average" and "below average." The limb tubes have a good deal of adjustment to fit a wide variety of knees and elbows. Jun 7, 2012

EPrider: I'm a 5'3" female, and the mediums fit my knees snugly. (I'm a cyclist though, so I have muscley legs.) Since you're a guy, I'd probably go with the Large for knees, unless you're a string bean. Apr 3, 2012
