versatile patagonia bib pants for your backcountry adventures . built for high-output comfort and motion, patagonia's lightweight, backcountry-ready snowdrifter bibs combine the uphill performance of a stretch fabric with serious storm protection to keep you dry and comfortable wherever you go in your powder pursuit. the h2noâ„¢ performance standard shell fabric is made of a limber 3-layer, 70% recycled stretch polyester ripstop that allows the full range of motion and blocks wind, moisture and hard use. a dwr (durable water repellent) finish prevents saturation and increases abrasion resistance. a moisture-managing liner of soft polyester knit increases comfort and provides a smooth glide when layering. the upper part of the bib is made with a lightweight double weave fabric (63% recycled) with four-way stretch that breathes easily, moves moisture and pairs nicely with other layers.the low-profile, full-coverage design includes drop-seat adjustability, removable suspenders (they detach in front for quick and easy entry) and two-way side zips for venting and easy relief. other details include articulated patterning through the hips and knees for full mobility, tough scuff guards for durability and low-bulk gaiters that provide a tight seal on boots. designed with three pockets to keep you organized (two thigh cargo and one zippered chest pocket) and an embedded recco® avalanche rescue reflector.
