While it has a thick rubber, the rest is thin fabric. A hole opened in the seam of the rubber after a few uses. I will not buy them again

It is a bit tight, so if you wear M, get L. The fabric is much better than cotton by a large margin, and this is because I had the problem on very hot days when you are at work in the morning and then go straight to the gym in the afternoon, no matter what you do you can't be dry, clean and odorless. Bamboo really surprised me as the underwear stays dry and clean all day long. I recommend it to those who engage in intense physical activity and to those who are on their feet all day and want to stay dry, clean and odorless.

All the boxer shorts from walk seem a bit wide to me and all the briefs a bit tight. They may be designed this way but next time I will get a size larger.

Nice underwear, perfect fabric, a little tight, (Minerva 90-20482 modal mengearl) the corresponding slip size L in bamboo XL

The best fabric to wear is Bamboo. Healthy, perfectly ventilated, you hardly sweat at all, it immediately absorbs sweat, and it's hypoallergenic. And it is perhaps the only Greek company in Athens that still stands and operates under Greek management and staff with all these adversities and the economic crisis. Let's prefer Greek products made by Greek hands. Amazing company with the best underwear, t-shirts, pajamas, etc.
