Discover the heritage of milk casein fiber in this Formula Tee. This regenerated protein fiber, popular during the 1930s-40s as a wool alternative, combines the best of both worlds. Like wool, it responds beautifully to wear and movement, yet offers superior moisture absorption and natural antibacterial properties. The cotton-milk blend enhances skin comfort while maintaining breathability. A timeless fabric choice that bridges vintage innovation with modern performance.

Perpetual Mountains
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."
