Why choose it

Merino wool naturally regulates body temperature, wicks moisture away from the skin, and resists odour, so you can wear it for days without washing. The Corespun technology wraps merino fibres around a nylon core, increasing durability without sacrificing next-to-skin softness. Flatlock seams and offset shoulder seams eliminate irritation, even under a heavy backpack. This shirt is an all-season performer, keeping you warm when it's cool and cool when it's warm.

Good to know

Machine wash cold on a gentle cycle, line dry in shade, do not bleach, do not tumble dry, cool iron if needed, do not dry clean. The ZQ certification ensures the merino wool comes from farms that meet high standards of animal welfare, environmental sustainability, and social responsibility.
