What Our Gearhead® Experts Are Saying:
"I threw these in my jersey pocket, not knowing exactly how cool the descent would get, and that ended up being the whole point. When the temp dropped, I pulled them up as full knee warmers, and on a milder day I just left the top folded down as leg warmers instead."
Some rides start warm and turn on you halfway up the climb, and Castelli built the Pro Seamless 2 Knee/Leg Warmer for exactly that kind of morning. We love keeping a pair folded down to almost nothing in a jersey pocket, ready to pull on the second a descent turns cold or a cloud rolls over.
The seamless construction means there's no bulky ridge to feel under bibs, just a smooth, mid-weight layer that keeps warmth in without cooking your legs on the climbs. Pull it fully up for a knee warmer, or stop just above the leg gripper and let it work as a leg warmer instead, one piece doing the job of two.
