Hikers wearing LOOW merino wool on the trail

Hiking for men

Merino wool for hiking

On a long hike the same shirt has to handle sweat on the climb, wind on the ridge and a cold evening at camp. Merino wool moves moisture away from the skin, insulates when damp and can be aired instead of washed, so you carry less. Here are the layers we pack for several days on the trail.

  • If you hike several days with everything on your back
  • If you want fewer changes of clothes in the pack
  • If you get hot uphill and cold in the breaks

Why merino on the trail

  • Comfortable in changing temperaturesMerino wool insulates against the cold and absorbs moisture from your skin, so you stay comfortable when your activity level and the weather change.
  • Wicks moisture and dries quicklyThin merino layers can often dry overnight after washing. Drying time depends on the fabric, ventilation and humidity.
  • Light and packs smallThin merino layers weigh little and take up little space, so you can pack fewer and lighter pieces.
  • Less odour and fewer washesMerino wool does not develop odour as quickly as many other fabrics. Often, airing it is enough between wears.
  • Soft against your skinFine merino fibres bend easily against the skin. The fabric feels soft and can be worn directly on the body.

      How many T-shirts do I need for a week?

      Fewer than you think. In our field test through the Pyrenees, 20 days were covered with two tops: one on the body and one airing or drying. Merino wool develops odour slowly and dries quickly after a rinse.

      How do I wash merino on the trail?

      Rinse in cool water, squeeze gently in a towel and hang to dry. Merino dries quickly, so a rinse in the evening is usually dry by morning. Avoid wringing.

      Which weight for summer hikes?

      135 is our lightweight fabric and the choice for warm days and high activity. Bring the zip neck or fleece vest for evenings and breaks.

      Does merino wool itch?

      Merino wool has finer fibres than coarse wool. They bend easily against your skin, so the fabric feels soft and supple. We select fine merino wool for our clothes so you can wear them directly on the skin.

      Which size should I choose?

      Open the product and use the size guide with garment measurements. Compare with a T-shirt that fits you well. Fit varies between styles, so use the guide for the item you choose. See the men's size guide.

      Can I try the clothes and return them?

      WOOL Club members can try clothing for 30 days, including wearing and washing. Unused items have a 365-day return policy. Returns and exchanges are free from Denmark and the EU. See our return terms.
