Marmot

Solitude UL Bio Jacket - Men's

What Our Gearhead® Experts Are Saying:

"I’ve put this shell through long climbs and windy ridges, and what stands out most is how breathable it feels for a 3-layer waterproof. The pit zips dump heat fast, the pockets stay accessible with a pack, and the fabric packs down smaller than most jackets in this class. It’s become my go-to touring shell when weight matters."

We zip into the Solitude UL Bio Jacket when the morning forecast looks mixed and the objective demands efficiency. Marmot’s bio-based ripstop and NanoPro membrane give us storm-ready coverage without the stiffness or noise of traditional shells, keeping us comfortable as we work uphill through rolling clouds and bootpacks that test our pacing. The jacket feels light in hand and on the skintrack, packing down easily when the sun hits but bouncing back instantly when the weather shifts.

Ventilation becomes essential as we climb, and the long pit zips open wide to cool us down on steep, technical sections. When the sky turns and flakes begin to fly, the fully taped construction and DWR keep moisture out while the helmet-compatible hood locks in focus. Inside, mesh dump pockets warm skins between laps, and the beacon-ready chest pocket keeps our essentials secure. Whether we’re racking vert before sunrise, grabbing a tram lap at lunch, or stitching together a spring mission, the Solitude UL Bio Jacket carries the features we rely on without weighing us down.
