Product Description: For Men's Sweat! "Armpit Sweat Prevention & Back Sweat Prevention" Covers the back in addition to the armpits?! Thoroughly guards against sweat stains with a 4-layer pad built into the armpits & firmly guards against back sweat with Teijin Dualfine's special material that absorbs sweat but is difficult to stain. Recommended for those who sweat profusely! Men's sweat-absorbing, quick-drying short-sleeved innerwear. Opened and washed, but unused. I bought it for a family member who sweats a lot, but they didn't like it and didn't even try it on... The cotton parts are not "pure white," but there is no yellowing as it has not been worn. Purchased last year from the official Cecile website for about 2200 yen.
