Patagonia PowSlayer Pants

Patagonia.com says:
The uncompromised PowSlayer Pants provide the highest level of stormproof performance available so you can focus on riding rather than second-guessing your gear. Built for movement (both up and down the mountain), they feature lightweight yet highly durable 3-layer 100% recycled nylon ripstop GORE-TEX PRO shell fabric for the highest level of waterproof/breathable and windproof performance. A DWR (durable water repellent) finish sheds moisture and wet snow and increases abrasion resistance. The low-profile, full-coverage design includes articulated patterning through the hips and knees for full mobility in all directions, side zips that let you fine-tune the venting options, tough scuff guards to protect the inside of the leg and the bottom of the hem, low-bulk gaiters that seal out snow when you're postholing and three zip-closing pockets (two thigh cargo, one at the right front hip). Watertight, coated zippers with slim-zip installation are less bulky and provide exceptional storm protection. At the waist, a zip fly, double-snap closure and grown-on belt loops keep the pants right where you want them. With an embedded RECCO(R) avalanche rescue reflector and an articulated silhouette. Fair Trade Certified(TM) sewn.
