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
Stealth knee pads These are easy on, easy off knee pads that can go under my riding jeans. They fit great and are ultra light and thin so they're barely noticeable. They will definitely help out more than the pads that most of my jeans can handle since these are always going to be in the right place. February 27, 2015
Better Protection For The Joints Good: These limb tubes do not slide or budge from their position, so when you fall you can expect that they will keep protecting that joint. I have a set for the knees and elbows and wear them under blue jeans and pseudo leather jackets. They breathe pretty well, i don't seem to sweat in them at all unless i am standing still in the sun. They don't bulge out of any of my clothes except when i wear slightly tighter jeans. very good if u don't wanna look funny wearing pads around a mall. Bad: For wearing on the knees, the bottom of the pad digs into the shin when standing strait and walking. (totally fine and comfortable when riding because the knees are bent). The tube itself is kinda cheap. It is like spandex. I can totally see it ripping to shreds in the washing machine someday or only surviving one nasty fall. If you're handy, i suggest buying the pads and making your own sleeve. Sizing: I bought 1 medium for the knees and 1 small for the elbow. I use the small on the knee and fabricated my own tube for the elbow and slipped in the pad. Look carefully at the sizing chart and remember to get a tight fit! not a perfect fit! Keep in mind that the tube material is like spandex and stretches. Like buying socks, they have it for sizes 5-10 and 10-14. if you're a size 10 you might want the 5-10 so they don't slide. Pads for the small and the medium are the same size, the difference is with the tube/sleeve. January 26, 2015
Fits nicely under pants Bought these to wear under my pants for the daily commute. They do the job nicely and add that extra bit of protection that I needed. I'm 6'0, 180lbs and ended up needing the medium size for a more snug fit. The large size was fine but I felt like they would slide down a bit after walking even a short distance with them. They also have the added benefit of protecting your knees and shins from wind chill on cold mornings. Overall, I'd recommend these for anyone who's looking for a low-profile pair of knee/shin protectors for use under any pants. Haven't taken a fall on them yet so I can't really say how well they actually protect, but they feel pretty solid. Needless to say, anything that keeps your knee cap from dragging on the pavement is beneficial. January 21, 2015
Added these to my collection.. .. and am glad I did. Operating inside the 'any armor is better than no armor' theory, the limb tubes are more toward the better side. They are light, comfortable and walking around the house testing them on door jambs and counter tops, I'd say they are good for the initial 3-4 foot drop from a motorcycle. Properly sized, they'll probably stay at least near where they should be assuming they are worn inside some substantial fabric. December 23, 2014
great for trials I got these for riding trials. They fit well, reaching down to the top of my boots (Gaerne Balanced Oiled), and are comfortable under my trials pants. The trials pants hold them in place tightly enough that I don't need the Velcro straps. I haven't fallen on them yet so don't have a report on that. I don't think they would provide enough protection for high speed get offs but I think they're perfect for trials. November 23, 2014
Nice Knee Protection for the Money. I bought this to add a small level of protection on my knees and also block a bit of the wind chill during those cooler spring and fall days. It does both those things wonderfully. They do have semi rigid CE protection that adds some thickness under your jeans. I like to wear slim fit jeans and they fit underneath just okay. Will not fit under skinny jeans for you hipsters. If you walk around a lot with them on, they will slide down away from your knee a bit. Pull them back up before you get back on your bike. No big deal. October 20, 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

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 (0) 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

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

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
