Description
The Merino 365 Men's Slim Pant is the quiet MVP of your layering system. Designed to sit comfortably next to skin, it’s cut from 190gsm of superfine New Zealand merino for soft, breathable performance that adapts to whatever you throw at it—whether that’s alpine starts, long-haul flights, or everyday winter wear.
Merino wool naturally wicks away sweat, keeps you warm without overheating, and won’t hold odour—making these pants a solid repeat-wearer between washes.
Lightweight, temperature-regulating, and ridiculously comfortable, this is the base layer pant that makes synthetic long johns feel like a thing of the past.
Merino 365 gear is designed and tested by real outdoor people in Aotearoa, for real-world adventure. Layer up and wear it every single day of the year.

Why Merino 365?
