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 & the special Teijin Dualfine material that absorbs sweat but is difficult to stain, firmly guards against back sweat. A sweat-absorbing, quick-drying short-sleeved innerwear for men, recommended for those who sweat profusely. 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.
