During the 1930s and '40s, "milk casein" fiber was all the rage in America and Europe, found in clothing and household items alike. This fabric, similar to rayon or viscose (made from wood pulp), mimicked wool thanks to its regenerated protein fibers. It was a soldier's best friend during times of wool shortages, but fell out of favor after WWII with the rise of cheaper synthetics like nylon. The blend of cotton and milk casein in this fabric also offers superior skin comfort, moisture absorption, and natural antibacterial properties. Other highlights include a handy Amundsen Oslo Tab, ribbed collar details, and a split side seam for ease of movement. Perfect for hiking, everyday wear, fishing, boating, travel, picnics, and outdoor adventures.

Milk Casein:
In World War II, when there was a shortage of natural fibers due to wartime demands, scientists created milk casein fibers as a substitute for traditional textiles. Made by wet spinning, these fibers use milk protein and can be used for clothing and bandages, offering a soft, silky and eco-friendly solution during the scarcity of conventional fabrics.

Our staffs insights
For the men's waist:
- M = feels more like a 30 inch waist
- L = feels more like a 32 inch waist
- XL = feels more like a 34 inch waist
Field Shorts:
- M = Initially feels like 30 inch waist, but slackens to more of a 31/32 inch
- Field Shorts slack fairly quickly so we suggest getting them a bit snug as they'll stretch
Other Points:
- Cord shorts and pants slack overtime compared to deck shorts and pants that remain the same.

ESSENTIAL LAYERS FOR ELEVATED LIVING
"This is mountain life at its most alive — where the air is thin, the rivers cold, and the gear as adaptable as the terrain. Here, our iconic checked flannel zips alongside soft fleece sweaters, field-ready mid layers, and super-light anoraks that pack down between summits. Worn over milk protein tees and long sleeves, these pieces are made to match the rhythm of long hikes, chilly mornings, and warm rocks in the sun. Built for summer above the treeline —where comfort meets function, and every layer earns its place."
