The underwear, as many have said, is quite tight, resulting in the testicles being in constant contact with the elastic.

Try a size larger than usual or one of the other similar models from sloggi.

I bought the medium size, just like in other sloggi panties and boxers in the past. These specific ones are tight, resulting in the seam coming out of the underwear, causing me discomfort in hot conditions. I believe that the money I spent was not worth it for the aforementioned product.
