Marmot Women's Midweight Half-Zip LS — $65
Marmot’s half-zip midweight base layer is popular for a reason — Polartec Power Dry fabrics wick away moisture while its activated carbon eliminates odours and even provides UPF 40 protection. Mobility is considered with stretchy fabrics in all the right places, and it even features a tag-free neckline (tags drive us crazy…) Add to this construction from recycled polyester and it’s hard to find a reason not to pick this one up.
