PrimaLoft® Gold
Earth-friendly PrimaLoft® Gold Eco Insulation is 55% recycled materials and withstands temperatures as low as -70° F. Built to handle moisture, this lightweight synthetic insulation is water resistant, retains heat even if it does get wet, and gets you back to dry faster than down.

Weather Protection
A 70-denier micro ripstop shell provides windproof and water-resistant protection while retaining breathability to keep you warm, dry, and sweat-free. Double-layer 40-denier CORDURA® ripstop mapped to key areas minimizes heat loss.

Made to Move
Stay movin' and groovin' through difficult terrain with articulated knees, and protect against wear and tear from spikes, crampons, and snowshoes with tall Cordura® nylon insteps. Stuff the whole thing down into the included sack when not in use.

Adjustability & Access
Four-point adjustable suspenders and a Velcro® waist cinch enable a just-right fit. Full-length zippered side vents with double wind flaps provide easy access without sacrificing protection, and a special crotch-to-rear zip fly allows you to answer when nature calls without taking the whole bib off.
