Product Customer Reviews
Purchased in September 2024, the panties already show signs of wear. However, my use is not "intensive", I wear them every 2 to 3 weeks! I hope that customer service will contact me again to find a solution, being in French Guiana.
Really comfortable to wear! It doesn’t stink and I can wear it for three days without taking a shower (wrong). But the size is confusing, I usually wear L and this one is just the right size for me. So, when will the S size be restocked? I want to stock up!
I have several of these underpants and I really like them. Unfortunately, the first pair of them ripped on both sides, where the fabric is thinner, after a relatively short time. Unfortunately, the underpants are no longer wearable. I wish the quality had lasted longer.
A must have for wool lovers. Comfortable, fitted and you can barely feel them. Mega comfort both in wearing and washing.
They work great during heavy exertion. The most important thing for me is that the rubber is not tight, it is just right - they hold well. Very good composition.
Very good to wear
I recommend
comfortable and light
Comfortable panties for sports, however I find that they do not wick away perspiration and odors very well (like the other merino products that I use regularly).
Excellent underwear that I wear every day, very comfortable.
Comfortable
For the price, it's a good way to try out merino underwear in general, but the cut isn't entirely flattering and the seams are very visible under clothing.
Perfect
I have been buying the briefs for a few years now and unfortunately I have noticed that they are becoming increasingly poorly made. They simply tear apart at the sides. They fray. It's a real shame.
Excellent panties, after personal experience I bought them for my mom as a gift
