Product Customer Reviews

Completely satisfied on all points
comfortable, dries very quickly
Purchased due to intensive use to have stock. I've had the old version for over a year, panties that hold up well.
Already 3 in stock top product
Used for the first time in mountain hiking over several days. Purchase of a 2nd car satisfied with the product.
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
Comfortable hiking pants
Fine material, super light
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 :)
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.
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.
