Merino Wool Base Layer Long Sleeve

Domesticated by polyester. Gone feral.

A men's merino wool base layer in 100% merino wool. Train in it, layer it, travel in it.

Why it's built this way

Synthetic base layers trap heat and smell. Merino regulates temperature in both directions: warm on cold mornings, comfortable when the pace picks up. It resists odour, so it handles multi-day trips without a wash.

Care

Wash cold on a wool or gentle cycle, inside out. Mild wool detergent, no fabric softener, no bleach. Lay flat to dry; do not tumble dry. Often all it needs between wears is a night of fresh air.
