Very good option

It allows you to feel fresh. It does not retain humidity and is very warm at night.

Size L seems huge, but they fit fine. Comfortable, warm. I recommend ;)

very comfortable but not very durable

very comfortable panties to wear, I bought around ten, I was delighted with them at first. but be careful, they all break in the same place: on the edge between the elastic and the fabric woven on the side, after a few months.

holes after a short time!

The underpants are very comfortable to wear, but after just a few washes they were completely broken in two places, with large holes. This is probably due to the thinner fabric on the side, it just tears. I strongly advise against purchasing!

Good product

Very flashy pink, good product but wears out quickly

Technically good but look…

Technically good but a bit rustic looking. The elastics could be more discreet and softer.

a bit of a big step...

a little big not too tight

Super great merino underpants, cut, feel and durability are great, keep up very well with more expensive products. Please bring more colors!

Use during a stay…

Used during a one-week roaming stay in Morocco, comfortable to wear and quick cleaning/drying.

Perfect for a 10 day trek

I bought several merino pants for a 10 day trek. Easy to wash by hand, quick drying and wicking away sweat and odors.

Perfect panties

They are great for all-day trekking and are so pleasant and comfortable that I sometimes use them on regular days as well. I like to wear them on days when I have menstrual pain - nothing bothers me.

Absolutely great

The panties are perfect, comfortable, fit well. There is nothing to add to the merino material. I will see the resistance after a longer time, in half a year so far great. I definitely recommend it.
