Patagonia Torrentshell Stretch Pants

Patagonia says:
The Enchantments earn their name in summer - as do the Cascade Mountains. In rain-drenched zones, pull on our Torrentshell Stretch Pants. They give full H2No(R) Performance Standard waterproof/breathable protection, and the 2.5-layer nylon ripstop fabric stays durable, while stretch panels in the articulated knees keep you high-steppin' in your rain pants. The full-length, two-way separating side zips have watertight, coated zippers (with snap tabs at the top and bottom), and the waist has a watertight zip fly with a snap closure. The waistband is partially elasticized and elastic at the cuffs seals out moisture.
