Arcteryx Proton Pant

100% POSITIVE

REVIEWED BY: Tyler Fuller

These pants are perfect for getting your leg layering dialed. Arc’teryx has designed a pant that provides the necessary warmth to keep your legs comfy and cozy on a chilly day, but breathable enough that they won’t be drenched after a thigh burning bump run. They achieve this through Ultralight Octa Loft knit insulation paired with a Fortius Air 50 nylon weave outer that is lightweight, breathable, and has four way stretch (a major key for making sure your mobility isn’t limited on the mountain). From the low-profile waistband design to the tapered cuffs these pants have a sleek, trim fit that is perfect for layering underneath your snow pants.
