UYN Biotrek Heavy Duty – warmth and comfort on the trail
Choose Biotrek Heavy Duty for more warmth on cool hikes and materials that help manage moisture around your feet. Merino wool, kapok and functional fibres make it a practical choice for changing temperatures on forest trails and mountain hikes.
Why choose Heavy Duty?
Warmth with breathability: merino wool helps regulate temperature as conditions and pace change throughout the day.
Moisture management: the fibre blend absorbs and transports moisture away from the skin, supporting a comfortable climate inside your shoes during long hikes.
Comfort on multi-day trips: merino wool naturally helps limit odour. UYN also uses Natex, a bio-based polyamide made from castor oil, and kapok in the blend.
