I'm 5'9" with a 32"(ish) inseam, and hover around 147lbs - my legs aren't particularly muscular right now but these stay in place well and don't bunch up...I can forget about them while I'm riding. I suppose I've had better warmers but I've also had more expensive ones that were much worse than these. I'd say that these are really good and for the money, they're excellent.
These hold n place well, are warm but not hot, and provide you with a great removable option
I wear knee warmers for skiing and bicycling in cool weather, these are top quality.
I am a bit disappointed in these. Hits just below the knee is what probably should have warned me. Im a 32 inseam, and ordered L. They hit just below my kneecap when pulled up all the way and ride up while riding, so their coverage isnt adequate. I considered exchanging them for XL, but based on the fit of the L, theyd probably be too loose. Disappointing and not very functional.
Fits well, stays in place, and keeps me warm. Easily rolls up and fits into a jersey pocket.
