Wool40 Aero Long Sleeve Women's

Wore this for a chilly morning run and the merino kept me warm without overheating, even as the pace picked up. The different knit zones really do pull sweat away fast—I stayed dry the whole time.

The different knit zones actually work—my back stayed dry during a sweaty trail run in freezing temps. Fit is snug but not restrictive, perfect for layering under a vest.

I’m honestly impressed with how quickly this dries. After a 10k in near-freezing temps, the sweat evaporated fast and I never got that clammy chill. The 3D knit structure makes it feel lighter than a standard merino layer, which is perfect for staying warm without overheating.
