Patagonia Men's R1(R) Pants

Predawn alpine start: zip shut the tent, get moving, and crank up the heat. On a body-steaming frigid approach, when it feels like you should be able to hear your freezing vapor make a sound like shattering glass, the stretchy mobility and surprising warmth of these simple pants enable your every escape. The improved high/low grid R1(R) polyester fabric (Polartec(R) Power Dry(R)) traps heat and maintains its warmth while letting you breathe, and is now even more breathable and compressible, with an improved feel and durability. The clean design allows for frictionless layering or stand-alone use as a tight. With a low-bulk, brushed-elastic waistband and a zippered back pocket. Recyclable through the Common Threads Recycling Program.
