DeFeet ArmSkin

I'm big on arm warmers for both cycling and running. These are nice. I wore mine yesterday on a 5 hour ride starting out in the cool temps of the morning (45 degrees F) and ending in the "heat of the day" (around 70 degrees F). I wore the warmers the whole time and was exactly comfortable. Exactly. Granted, I was out there for hours by myself, and I had a ton of time to think, but I actually noted how comfortable the warmers were. CoolMax's breathability and moisture control work well not just to keep you cool, but to keep you warm enough. And that's the point. These are warmer than many lycra options out there. But you don't necessarily get too hot when the temps rise.

Also (and this is important), I like Defeet's cuff and the snug fit. These don't fall down. Even while I'm running.

The material is soft and comfortable. More like socks for your arms than lingerie for your limbs, which is how I feel sometimes when I'm sporting the lycra.

Not that there's anything wrong with lingerie.

-comfortable, love the no seams
-unique pattern
-rolling top is comfortable but rolls down a little, leaving you with the tan stripe below your jersey sleeve
-warm but wicking (although my arms don't sweat much, so who knows)
-not very tight, even though I got smalls
