It can be used as a rash guard, as well as for various activities such as mountain climbing and running. I am also selling other mont-bell wear, such as the XL size of the long-sleeved shirt of the same product, as well as various other sportswear. #Kamimontbell #Kamimountainclimbingwear #Kamithenorthface #Kamicompressionswear #Kamiundershirt #Kamisportswear #Kamishort-sleevedwear 〈Manufacturer's Description〉 This long-sleeved shirt is effective in protecting the skin from scratches and sunburn, as well as preventing the body from getting cold.

Specifications 【Material】Polyester 74% + Polyurethane 26% [Water-repellent treatment] 【Color】Light Gray (WTSM) 【Size】M 【Features】Spiral Slantec® Cuff ■Amazing Water Repellency Durable water-repellent treatment that does not deteriorate even after repeated washing is applied to each individual fiber. Compared to general rash guards that only have water-repellent treatment on the fabric surface, this achieves amazing water repellency throughout the entire garment. Water does not cling to the body, minimizing the chill when coming out of the water. ■Comparison of Heat Loss When Wet Aqua Body Series: Due to the strong water repellency of the entire garment, the garment itself does not retain water, and water does not cling to the body, minimizing the chill. General Rash Guard: If the water repellency of the garment is weak, water clings to the body. Water has a high thermal conductivity, so it rapidly draws away body heat, causing a feeling of coldness. ■Amazing Stretchability The fabric has outstanding stretchability. By reducing the number of seams, the stretchability of the fabric is maximized. It follows various movements in the water and intense movements during paddling without stress.
