The women's Patagonia Powslayer Bib is made for backcountry ski days on the skintrack. The lightweight GORE-TEX PRO shell is waterproof, breathable, and windproof, and watertight two-way side zippers double as vents when you're climbing. A drop seat makes bathroom breaks easier, and the zip fly with grown-on belt loops lets you lower the bib while hiking. Bellowed thigh pockets expand to hold gear and lie flat when empty, and gaiters help seal out snow.
