ウィメンズ ザ・ワンベスト

Wore this on a windy ridge hike and it blocked the gusts without turning into a sweaty mess. The stretch makes it easy to layer over a long-sleeve without feeling restricted, and it packs down small enough to stuff in my daypack.

The Aeroknit really does keep me from overheating on chilly morning runs, and it's light enough that I forget I'm wearing a layer at all. I've wiped out light rain on it too and the water beaded right off.

Wore this on a windy hike last weekend and barely felt the gusts, yet I never overheated on the climb. The Aeroknit really does regulate temperature well, and it packs down small enough to stuff in my daypack.
