Composite construction jacket with versatile thermal management and zonal weather protection in a single garment. Alpha Series: Climbing and alpine focused systems.
DESCRIPTION
Ice climbers and alpine climbers move quickly, generate a lot of heat yet require waterproof protection from spindrift, water, and falling snow. Streamlined for light weight and energy efficiency, the Alpha Comp Hoody has a trim fit to maximize fabric technologies and provide clear lines of vision, with e3D (ergonomic, 3-dimensional patterning) to accommodate free movement of layers.
Composite construction combines two very different materials in a manner that maximizes the benefits of each. In the Alpha Comp Hoody we use Fortius 1.0 stretch woven fabric to regulate heat and provide stretch through core and under the arms. N40p 3L laminated GORE® Product Technology provides durable weather protection across the hood, shoulders, forearms and hem.
A helmet-compatible StormHood™ fits securely and adjusts rapidly with one hand movement. Zippered chest pocket and hand pockets are secure, accessible while wearing a harness or backpack and easy to operate while wearing gloves.
The refined two piece Hemlock™ inserts prevent jacket slippage, are compact and fold easily for storage.

Arc'teryx Fit Guide - e3D
Ergonomic 3-Dimensional (e3D) patterning brings an additional level of articulation to provide enhanced range-of-motion in our Trim, Athletic, and Expedition fit categories. The application of e3D patterning allows for enhanced mobility for sport-specific activities in challenging environments.
Arc'teryx Fit Guide - Trim Fit
These trim fitting garments share motion-friendly traits with our Athletic fit, but are patterned with lower volume for reduced bulk. Our trim fit is sized for a base layer and a trim synthetic or down filled mid-layer
