Powerfully versatile softshell that performs as a midlayer in moderate cold or on its own for active pursuits in cool weather. A lightweight polyester grid fleece is bonded to an abrasion resistant nylon woven face fabric. This combination creates a single material that effectively insulates and moves moisture while delivering breathability, weather protection and stretch performance.


Arc'teryx combines materials, intelligent design approaches and real world testing to create clothing and gear that meets the highest levels of functionality. Based in Vancouver, B.C., the designers' access to the mountains and coastline provides a versatile testing ground with a variety of weather conditions, the perfect laboratory for softshell development.


Arc'teryx designs to deliver maximum function and performance freedom. The Epsilon LT Hoody's streamlined athletic cut minimizes snags and easily layers under a hardshell. The hip length cut delivers additional protection when bending or reaching. Gussets are built in for increased range of motion, and ergonomic articulation is part of the patterning.


The grid pattern inside efficiently traps warm air, and allows moisture vapor to move away from the body and easily escape. On the face, nylon weave provides abrasion resistance, air permeability, protection from light weather, and exceptional stretch performance. By bonding fleece to a nylon face, a single fabric provides maximum versatility.
