Dame Larkspur-vest

I've worn mine under a shell on two damp spring hikes now, and the breathable membrane really does keep you from stewing on the climbs. Core stayed warm even when I stopped for lunch in the wind.

Wore this on a windy ridge hike and my core stayed warm the whole time while my back never got clammy. The breathable membrane really does keep rain out without turning into a sauna. Packs down small enough to stuff in a side pocket too.

I was skeptical a vest could handle both sweat and rain, but after a damp 10-mile hike the breathable membrane really did its job—no clammy feeling under my pack. Plus the core warmth lasted through a chilly summit break without me having to layer up. This one's earned a permanent spot in my daypack
