RICARO Sleeveless Polo Shirt Color: Pink Size: M Uses "Aqua Miracle T1000," an active sports material developed by Asahi Kasei with a focus on sweat, pursuing not only comfort in wear (sweat absorption, quick drying) but also visual comfort. The fabric surface is constructed with a two-layer yarn containing a high concentration of white pigment. This provides an effect that makes "sweat stains," which can be noticeable when sweating, less conspicuous. It features excellent sweat absorption and quick-drying functions, anti-transparency effects, and 95% UV cut functionality. The nape of the neck is designed to be 7cm long to prevent sunburn. It's cool when the zipper is open. The zipper incorporates Swarovski crystals.
