The Arc'teryx Cormac Crew LS is a technical long-sleeve performance top meticulously designed for versatility across a vast range of high-output mountain activities. Whether you are trail running, fast-packing, or hiking through varied terrain, this top delivers an exceptional balance of moisture management, sun protection, and lasting comfort against the skin. Constructed from 100% recycled Phasic™ LT fabric, the Cormac actively pulls moisture away from the body to keep you dry and comfortable during intense efforts. This updated grid-textured material is not only lighter and softer than previous versions but also features a DAO (Durable Anti Odour) finish to keep the garment fresh over long days in the mountains. To ensure maximum protection in exposed environments, the fabric provides a UPF 50+ rating, effectively blocking harmful UV radiation. The fit is refined for athletic movement, featuring a low-profile collar and strategic seam placement that minimizes friction and chafing under a backpack or hydration vest. This makes it an ideal standalone piece for shoulder-season missions or a highly efficient base layer for colder conditions. Specs: Gender: Men's.

Made from 80% recycled polyester, this fabric is engineered for rapid moisture wicking and high breathability. Sun Protection: UPF 50+. Provides elite-level protection against ultraviolet rays on snow or in high-alpine sun. Fit: Regular fit. Designed to maximize airflow and move naturally with the body without feeling restrictive. Seams: Merrow stitch seam construction to reduce bulk and prevent irritation during repetitive motion. Weight: 135g – ultralight for its class.

This cotton flannel shirt is an all-rounder for the everyday outdoor lifestyle

Designed with comfort and ease in mind, from adventures on the Savannah to picnics in the backyard. For hot days when breathability and lightweight freedom are a necessity.

“Milk casein” fiber was used in many garments and household items in America and Europe during the 1930s and ’40s. It’s made using a process that is similar to rayon/viscose (derived from wood pulp), but because it’s a regenerated protein fiber, it reacts like wool. Historically, it was used as a wool-alternative, advantaging soldiers on the front lines in times of wool scarcity. However, it fell out of use after WWII ended and newer, cheaper synthetics such as nylon grew in popularity. The cotton/milky fabric improves skin comfort, moisture absorption and is naturally antibacterial.

This endlessly comfortable shirt will become a challenge to not throw on, day after day. Inspired by the classic rugby shirt, we added corduroy details on the chest pocket and collar to add textural detail and fabric variance.
