EDZ merino wool briefs

This is a review of EDZ’s merino wool briefs for men. These merino briefs are also available as boxers.

My pair were brand new and untested before my 1,200 mile wild camping LEJOG and 3 Peaks walk, where I ended up wearing them every day.

I had planned on wearing them when it was cold and relying on my trusty Rohan synthetic pants most of the time. But I managed to leave the Rohan pants in the car on day 5, when I left my family in Perranporth. So I found myself with these as my only pants during the rest of the walk.

Then I intended on buying some more pants but I am a bit fussy. By the time I passed a Rohan store, some weeks later and a long way up the country, I had fallen for the EDZ briefs. I was able to wash them, wring them out and, if I had to, put them straight back on wet. Being 100% merino wool, they felt comfortable and warm within minutes of putting them on. I would forget they were wet and before I knew it, they were dry.

Testing the briefs

I never wore these pants at night during my LEJOG walk as I had leggings to sleep in, but I wore them continuously for 57 days. They never smelt bad, changed shape or become uncomfortable in anyway, even when wet.

I then used them again in summer 2020 on my 1,100 mile Dover to Cape Wrath walk. I didn’t think the EDZ briefs would be suitable for summer hiking as they are merino wool, so I started this walk in Rohan Alpha silver briefs instead. The Icebreaker Seamless Boxers were my second pair. When I reached Scotland (cooler and wetter weather), I tried the EDZ briefs again and stuck with them for the rest of the walk.

Sizing and fabric

The EDZ briefs seem to fit to size. I find all EDZ clothing is correctly sized, neither compression tight nor overly loose.

  • Superfine 200gsm merino wool
  • Naturally antibacterial
  • Absorbent, wicks moisture & dries fast.
  • Flat seams
  • Washing – machine wash 30C


The 100% merino wool content is good for body climate control in hot and cold conditions. It’s a natural material that’s good for the environment, and is not going to be adding to the plastic pollution in our oceans every time they are washed.

They’ll be suitable for any long distance hiking or as everyday wear, especially if you’re unable to wash them regularly. They are warm and comfortable next to the skin even when wet.

They were perfect for my LEJOG walk. Unbelievably, even after walking over 1000 miles in them, they showed no signs of wear. They were equally good during the warmer weather of my Dover to Cape Wrath walk as well.

I was so impressed with these EDZ briefs that I now have 18 items of EDZ clothing. I think it’s good quality and excellent value for money. Check out the EDZ briefs Amazon price here and price here.
