Field Test: Pack this 10.5-ounce shell when you expect four seasons in one day. Montane uses DV Storm, the lightest, most breathable version of eVent membranes that rely on “microscopic pores.” On hikes and climbs, it vents before my exertion overheats the shell’s interior.
Why It’s Timeless: Even in high summer, I’ve found hail, snow, and rain in the alpine. $400; montane.co.uk —Olivia Dwyer
