So, I've worn these twice now, for rides that lasted about 2.5-3 hours. And I like them!
Temps today were in the high 50s and the last time I wore them it was in the low 60s. They were more than warm enough.
I'm 5'7". With the LG Neo Power shorts, which are pretty long, these "knee warmers" almost cover my legs all the way down to my ankles. So with my DeFeet Wooleators socks, only a few inches of my legs are uncovered. If I wore longer socks I could have total coverage.
They stay up fine. Today they started to slide down a little when I first started riding, but I just had to pull them up a bit around the knees to solve that problem. After the ride I was cold so I left them on when I changed into sweatpants, and after three hours of running errands and several trips up and down the stairs to unload everything from the car, they're still in place. They're also reasonably comfortable -- I put them on more than 6 hours ago and there's a little snugness at the top but they're not really tight or binding.
Under the Neo Power shorts, which has a wide band and no gripper around the leg bottoms, they look okay -- much smoother than my old knee warmers which have grippers at the top.
I'm thinking of buying another pair to wear under sweatpants when I'm out walking in cold winter weather.
