Description
The Merino 365 Men's Base Pant is the quiet MVP of your layering system. Designed to sit comfortably next to skin, it’s cut from 190gsm of superfine 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 stays fresh, 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.
Fabric & Care
- Fabric: 100% Merino Wool, 190gsm
- Care: Machine wash cold on gentle or wool cycle with wool detergent. Lay flat or air dry.
- Origin: Made in China or Fiji
Why Merino 365?
Merino 365 was born in New Zealand and built for the outdoors. We use only premium, ethically sourced merino to create high-performance garments you can wear year-round, for sport, travel, or just staying warm every day.

Love it.
Would have like one in blue too

Great quality and very comfortable. Warm without being bulky, soft against the skin, and perfect for cold weather. Highly recommend. 👍
High quality merino that feels smooth, thick yet soft, very well-made.
The fabric is very soft with excellent construction. Fit is very comfortable. Overall excellent. I am planning to buy a few more pair.
This base pant is very comfortable and doesn't itch at all. It is keeping me toasty warm during this cold winter and I love it!

These are the perfect merino base layer pants. I'm 173cm tall (5'8") and got the 2XL-- the pants are not too long, and they'd still work for taller people. The fit is fantastic and they're so breathable. I'm usually on the warm side, and until I got these pants, I wore shorts around the house, but now I wear these all the time! I raved about them so much that my partner ordered one herself (along with a top). I'll continue to tell friends and family about Merino365, and I'll be buying more products from them in the future.
Love it.

Great quality product.keeps you very warm and comfortable
Nice soft feel. Larger fitting. I would normally wear large to extra large but medium fit perfectly.
very soft and nice to the skin
Nice product, quite a baggy fit which is not really want you want for an under layer though.
Great thanks and sox also wonderful
Good product, fast delivery and friendly service
Another quality product bought from you guys. Thanks a lot!
Great service. I made a mistake on my order and only realised after. Sent a brief email. Fixed it at their end. Love the gear we purchased and best service. Thank you
Bought two for my husband and one for my brother . Keep coming back to find other great items . Amazing quality
Really impressed, great value
Top quality and excellent service
Haven't used them as I got them on a freebie with another item purchased and the only size left was one size up from my size, but they look good quality and will likely be passed onto someone who will fit them.
Great men’s tights to wear as a base layer. The fabric is very soft and thick but breathable. The waistband is great - no chafe. Runs true to size also
This is my second order from merino 365 and everything I ordered is just as comfortable, beautiful and high quality as my first order. I also must say, this company has THE BEST customer service I have ever experienced. I had a strange issue with the delivery to no fault of the company and they were so genuinely kind and helpful in figuring out what was going on. I couldn’t recommend this company and their products enough. My husband got a few items and they have made him a believer in wool clothing ❤️
Super comfy and loose fitting. Not atall itchy like some merino. Love them
Top quality goods and really nice people to deal with. I will be buying from them again.
excellent quality
Extremely comfortable and versatile!
