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.

Women's Crew T-Shirt Short Sleeve
Great quality merino T-shirt, fine merino fabrics with a very silky-soft touch on skin and thermo-regulating. I love it... and the deep sea color too! Sizing is regular - not too loose fit neither slim fit. I have 3 merino 365 tops... there are an awesome value for money!

Husband loves it
Now he thinks it's hard to come back to cotton underwear after these merino ones!
Supple and soft on skin, really agreeable to wear, although he said he thought it wasn't that soft during the first 30min or so and then he forgot about it and wants to just wear these
