The Flylow Lab Men's Coat is a storm-fighting three-layer shell built for the rigors of the backcountry. Waterproof, breathable, and fitted with a clean, functional feature set, it shrugs off wind and heavy snow while still venting hard on the climb. It is the kind of do-it-all hardshell you trust when the weather turns and you are committed to the line.

Why we like it:

The 14-inch pit zips are the detail we lean on most; they dump heat fast on a sweaty skin track, then seal up tight for the cold ride down. Five well-placed pockets keep skins, snacks, and a phone exactly where you want them.

Features and Functions:

The Lab is built from 100 percent recycled polyester three-layer GORE-TEX, a PFAS-free membrane that delivers top-tier waterproof, windproof, breathable protection. A 3-way adjustable, helmet-compatible hood seals out weather, a removable powder skirt locks out snow, and the five-pocket layout includes a Lycra sleeve pocket and a sleeve pass pocket. Long 14-inch pit zips handle heavy venting.

Fit and Sizing:

A backcountry-ready fit moves well over a midlayer with room to layer underneath. True to size, with a longer cut for coverage on deep days.

Bottom Line:

For human-powered missions and lift-served storm days alike, the Lab is best at hard-charging all-mountain skiing in serious weather. A bombproof shell for skiers who go where the snow is deepest.
