The Active Merino Liner Short

Nero shorts with the waistband lifted to show the built in merino wool liner

A 100% GOTS certified organic cotton shell over a 100% merino liner at 17.5 micron, RWS certified with no mulesing. Two open pockets, one secure zip pocket, 5.5 inch and 7.5 inch inseams.

  • Moisture moves into the fibre, not across it. Merino absorbs water vapour into the fibre core and releases it to the air, so odour compounds stay bound inside instead of sitting on the surface.
  • Zero petrochemicals. No polyester, no nylon, no elastane, no recycled bottle flake.
  • Merino sourced and produced in New Zealand. RWS certified, no mulesing, under OEKO-TEX Made in Green and WRAP.

The shorts are where most men start. The rest of the range, tees, vests and boxers, is in best sellers.

5/5 – Best Shorts I've Ever Owned

I bought the Nero Shorts made with wool and organic cotton, and I can confidently say they're the best shorts I've ever worn. The material is next-level, breathable, soft, and somehow manages to feel both lightweight and durable at the same time. The fit is perfect, relaxed but sharp, and they move with you without ever feeling bulky or stiff.

They've quickly become my go-to for everything from casual wear to lounging, and I genuinely notice the quality every time I put them on. The wool keeps you cool when it's hot and warm when it's cool. You can tell these were made with intention and attention to detail.

Highly recommend. I'll be buying another pair (or two).

Comfy and practical

These are some of the best shorts i've ever worn! Comfy, good pocket size, sits well on the booty! The merino on skin is really cosy, while the cotton outer always looks good! Finally found a pair of shorts that are good for me and the earth!
