Perfect hiking companions

I've been using the merino briefs for 2 weeks on a long-distance hike and wash them every day. They can be cleaned very easily even with a little detergent and dried overnight. Unfortunately, the seams on one of them aren't that durable and I had to sew the side panel back on, and the elastic waistband tore after just a week. However, the other slip is like new. You should probably pay more attention to the processing of the individual product when purchasing.

Very soft, if you sweat, it gets wet but then it dries

Must item as a mountain hiker

Fine material, super light

comfort during the trip

It is worth investing in high-quality underwear. Well-fitting guarantees comfort during the hike. Personally, I think that the feeling of not feeling wearing underwear is the best judgement. This is the case here. I will add that the material is extremely nice, and the model is extremely comfortable. I highly recommend :)

Mixed reviews!

Comfortable. Used so far for day hikes: RAS! I bought 3 panties for a 15-day stay with hand washing: 2 of the 3 panties had holes on the side in less than 15 days! In short, comfortable but frankly disappointing on the solidity of the product (all the more considering the price!)!

Super comfortable and dries quickly. The size is a little big.

Fits large

Attention it runs really big, I ordered size L first but I had to return it because it was huge.


Very comfortable. Holds well. S for a well cut 38.

It is very worthwhile to recommend my wife to buy it for the trip to Mount Fuji in Japan.
