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.

Knitted in Italy from long‑staple Egyptian cotton, the Lascar Crew Neck captures the spirit of a classic college jumper. Ribbed cuffs and hem keep the silhouette tidy, while the soft knit make it an easy layer for everyday sport, coastal living or city routines. Finished with the weathered red triangle at the collarbone and the Spirit of Amundsen patch on the sleeve.

Reviving a 1930s innovation, the Formula Tee is made from a jersey that blends 50% organic cotton with 50% viscose milk casein.

Finished with a ribbed collar, split side seams and the Amundsen Oslo tab on the right side. A clean, regular-fit staple for city days, travel and light adventure.
