Design intéressant, mais le boxeur ne résistera pas longtemps. Il sera rapidement trop grand pour taille moyenne. Suggestion, trouver manière d'indiquer le devant de l'arrière.

Very comfortable great underwear! It does shrink a bit in wash & I do find I needed to go up a size than I expected. Sometimes I can getaway with a large but I definitely needed the extra large for these!
