The Patagonia PowSlayer Bib Pant is a pair of backcountry ski bib pants built from a lightweight, packable 3-layer GORE-TEX PRO ePE shell that is waterproof, breathable, and windproof. Articulated patterning and a stretch-mesh high waist keep the cut moving freely, and a recycled upper panel adds breathability. What Our Gearhead(R) Experts Are Saying:"On a long skintrack I open the side zips to vent the heat once I'm working, and I close them again at the top, so I stay comfortable without stopping to strip layers. The drop seat is the reason these stay on all day, since nature calls don't mean taking the bibs off."
