Men's Merino Long Johns 320

Heavyweight 320gsm merino is our warmest weight, built for deep cold and low activity such as winter camping, fishing, stalking and long days on the chairlift. 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.
