Men's Merino Long Johns 250

Midweight 250gsm merino is the classic winter base layer for hillwalking, skiing, snowboarding and cold commutes. Compare every weight in our merino weight guide.

Snug from waist to ankle, so they wick properly and do not bunch under trousers or salopettes. They are true to size; check your waist and inside leg in the size guide.

Turn it inside out and machine wash at 30°C or lower on a wool or delicate cycle with a wool-safe detergent. Skip fabric softener, dry it flat or on a hanger and never tumble dry.
