The Treeline Shell Jacket Women’s from Peak Performance is a lightweight, waterproof shell designed to protect you from wind and rain on outdoor excursions. With a clean, regular fit, it works as a reliable outer layer whether you’re hiking, camping or moving through town on a wet day.
Constructed from 100% polyurethane and featuring HIPE® technology in a 2.5-layer build, this jacket keeps water out while allowing moisture vapor to escape. The unlined design helps trim weight and bulk, and the regular fit leaves room for a mid layer or fleece, so you stay comfortable as conditions change without feeling overstuffed.
In a 2.5-layer construction, a waterproof membrane is bonded to the outer fabric with a thin inner print instead of a full lining, cutting down on material and making the jacket lighter and more packable. HIPE® is Peak Performance’s own laminate system that combines waterproof protection with breathability, helping to keep you dry inside and out.
