Although sloggi has quality underwear, I can't understand why they are so small.
I wear a medium size (in rare cases, I go up to Large) and I had ordered some other underwear from the same company in medium a little while ago... as they were in the box, I gave them away, they were excessively small!!
I decide to get these specific ones, this time in size XL (I remind you, I am M)...
Yes, they fit me, yes I wear them, BUT an XXL would be even better... if possible! What logic is there for a Medium person to have to buy XXL underwear in order to be 100% comfortable?? Whereas in no-name underwear, my L is big!!!

The sizing does not match (in the website description) and the product I received. While it lists 52 as XXL, the box says 46 (which is correct). I will give them as a gift (since that's possible) so I don't have to go through the return process and I will order the 56 (actual 48). Other than that, the product is excellent..

Comfortable briefs, but I have doubts about the composition stated (95% cotton, 5% elastane). I think the elastane is more than 5%.

Durable, high-quality cotton material with a nice, snug fit, the well-known and expected quality of sloggi. It comes tighter than the other ones I have tried. Very durable.

I received this particular underwear a few days ago. At first, I thought I had gotten the wrong size because I ordered XS and I received S. However, upon searching, I found that the smallest size for this underwear/design by sloggi is 36. In my measurements, the underwear fits perfectly fine! As an example, my measurements are 73cm & 93cm for waist and hips :) Additionally, the fabric of the underwear is relatively thick, which is good. I believe for this type of underwear, you don't want it to be see-through fabric. Lastly, I think the design is discreet, but if I had to describe it, I would say it resembles men's briefs.
