Sweat-Absorbing Sleeveless (Half Length) Set of 2 Purchased new and only worn once. Since it has been worn only a few times, I think the condition is good. However, please understand that this is based on my personal storage and inspection. Size: L Color: Black and Clear Beige Material: 30% Cotton, 30% Polyester, 20% Rayon, 20% Polyurethane The following is a reprint from the official website: This product is a dedicated half-length innerwear designed to stylishly and comfortably wear T-shirts, based on the concept of effectively placing fabric in areas where you sweat, and leaving other areas "cool = not wearing anything." - Coolness as if you're wearing nothing Achieves extreme weight reduction by applying fabric only to necessary areas. The half-length design makes it less stuffy and comfortable to wear. - Integrated absorption design that surpasses conventional side pads The two-layer pad and the side body are integrated, further increasing the absorption area and reducing sweat stains. It firmly guards against underarm sweat, so even those who sweat a lot can feel secure with this one piece. - CUT OFF® finish that doesn't interfere with the T-shirt silhouette The collar, sleeves, and hem have no seams, making them less noticeable under outerwear. It has a smart design. - It's hard to see through, so it also solves the problem of nipples being visible Just by wearing one, you can feel secure even under see-through T-shirts. *There are individual differences in how much they show through or are noticeable. - Neat and smart neckline design With a wide neckline, the innerwear won't peek out, keeping you looking clean.
