Nice knee pad replacements, but won't fit in Dainese New Drake Air Textile Pants Nice knee pad replacements for Dainese New Drake Air Textile Pants but they are too small to stay in place. The provided armor for the pants cut into my knees when tucked. These pads are better but are not tall enough to sit correctly in the pants. These are still better since they do not hurt to wear.

Well worth the money but check sizing This is a great aftermarket armor piece. These are a good bit lighter then some of the heavy plastic and foam knee pads, and they breath much better. I got these as replacement armor for my Olympia airglide 4 pants and I love them. They are light, the precurve fits well (could be a bit more flexible), and they aren't very noticible when wearing them off the bike. The only thing I can find wrong with these is that they are a bit large. The extra size is great and I'll be better off for it one day when I go down, but some pants might not take them. They just fit into my airglide pants and I have a pair of Tour Master pants that won't take them. Over all I'd highly recommend this product. Safe riding to you. April 3, 2016
Great protection cheap I put this knee armor in a pair of Kushitani EX country jeans (waterproof leather embossed with a denim pattern so they really just look like jeans) and it disappears well enough to wear all day without people asking why I've got big bulges in my knees. On a sportbike (like my 09 GSXR 600) they shift up quite a bit and poke out funny, but I think that's just the nature of jeans style pants with armor. I've considered adding a second cut about 1.5" below the existing one so they flex easier. On a standard, they're perfect. A pair just like these likely saved my left leg from being amputated after a nasty crash on 1/28/12. I ended up with a lateral femoral condyle fracture and a slightly compressed patella. Without armor, or with softer thinner armor, I've no doubt my patella would've been in pieces and my femur much worse off. I highly recommend never getting never getting on a bike sans armor, even if it is thin soft stuff, but for $40, why not buy the best? February 23, 2016
good armor Used these as replacement armor in my rain suit. So far they have remained untested :-) The armor feels good, much larger then the armor that came out, but clearly superior to the stock cheep armor which came with the suit. El Nino is upon us so good armor for my rainy commutes at least makes me feel better. January 19, 2016
Exxcellent upgrade for riding pants I have a pair of Joe Rocket Ion pants that I wear, and the knee protection in them is pretty sad. The hip protectors are good, but the knees? Not much more than a 1/2" thick piece of foam. And small at that. These pop right in to the knee pockets - and are MUCH larger and nearly fill the entire pocket - which is good! They stay in place a LOT better thanks to their pre-curved shape. In fact, for the first few weeks they were TOO curved and rubbed on my knees. But I rode through it and they have settled in nicely. They flow pretty good air when there is air to flow. My pants have solid knees, so I only get a touch of mesh down low - and you can feel the air through them. So they don't add any extra insulation - they are nicely perforated. Kneeling on the ground confirms these are comfortable and provide very good coverage. They stay in place, and were relatively affordable. A great upgrade to existing pads. June 29, 2015
The best thing about this armor is that you don't know it's there. I am completely satisfied with this knee armor. It quickly conforms to your body. Once it was in place I forgot that it was there. Luckily I have not had the need to test it out, but it feels like it would perform as expected. I will probably replace all my armor with this armor at some point. November 3, 2014
Good upgrade for my Tourmaster pants My riding stats: Daily commute, rain or shine. Roughly 1 hour give or take 20 mins (DC traffic), ranging from 80mph to stop-and-go. Still a rookie rider though- started in February. After a couple of months fiddling with the knee armor in my tourmaster flex pants (AWESOME pant, btw, highly recommend for others looking for a very adaptive pant to go over your work clothes), I figured it was time to upgrade. The stock armor protected nicely but it just wasn't the right shape for my tree-trunk legs, and the hard plastic construction would sometimes dig in to my knees while riding. Nicht so gut. I'll start with the negatives. I ordered these as an upgrade after much searching (not easy to find verified fitment info for these pants). These inserts are much longer than the stock armor (hence the slightly large fitment rating), and much softer (hence the slightly lower protection rating). It was a tight fit at first, but once they were in its like they were tailor made. I have no doubt that these will save my skin if I go down, but they are a bit softer and a very unscientific pound-my-fist-on-my-knee-while-wearing-the-inserts test yielded less pain to my fist and more to my knee than the stock armor. They are also a bit more than I would like to spend, but no product is perfect. I can't speak to air flow since its currently cold out and my pants are all sealed up from the wind. Pros- 1000x more comfortable than the stock armor. I hardly notice its there, and that's the main reason I wanted to upgrade. Also, no offense to tourmaster, but I just plain trust the Forcefield armor rating better than Armadillo, so despite having a softer insert that seems to transmit more impact from a fist bump, I'm betting that these will provide much better protection in the event of an accident. Overall I'm very happy with this product and with Revzilla's once again fast and flawless service! October 25, 2013
Does the job OK Well, it's knee armor...and I'd have to crash to really test it...and luckily I haven't done that. I bought this to replace the knee armor in my olympia Airglide pants. I couldn't make the stock pads fit...they were too short in the stock position, but too long to fit in the pocket if I raised them up. These pads are longer than the Olympia pads were, so lengthwise they work better. But the Olympia pads were a bit wider...I feel if they had been the right length, they'd have covered my knee better. They seem, when I hold them, to be better made and a better 'protection'...but that's just a subjective observation. for me, the point was that they were longer, and so they cover my knee better than the stock pads.
