Natural Fibre Outdoor Clothing

We only use animal products sourced using the most humane farming methods.

Wool is insulating, breathable, temperature regulating and odour resistant.

Ultrafine merino wool is super soft, faster drying, and has an incredible warmth-to-weight ratio on top of that.

Ventile® is a high-tech cotton weave made from the highest quality cotton. It's naturally windproof and more weatherproof than modern softshell fabrics.

Cotton feels great to wear with exceptional breathability and durability.
