Brisk fall days in the Tetons, mixed climbing burns at Ouray, and uphill skinning in a snowstorm: the Piton Hybrid doubles as a durable midlayer or a light shell. Its trim design features a durable Polartec Wind Pro fabric in key areas (elbows and front, then wrapping over the shoulders and down to mid-back) with Hardface Technology that enhances the Deluge DWR (durable water repellent) finish for increased water repellency and abrasion-resistance. The remaining areas use super breathable, stretchy and wicking Polartec Power Dry fabric, creating a flexible body-mapped design that lets you wear the jacket as a moderate-conditions outer layer until it's time to don a full-on shell. The one chest pocket and two zippered handwarmers are pack- and harness-compatible, while an absence of shoulder seams allows pack-wearing comfort.
