BILLABONG Billabong Inner Pants SURF UNDERSHORTS These under shorts are made of matte tricot material and are worn under board shorts, with an icon on the side. Matte tricot is a material uniquely developed as surf under shorts, combining excellent support and functionality. By using high-quality polyurethane, it achieves high elasticity, and moderate kickback provides excellent support. In addition, it is made of a material that is excellent in water absorption and quick-drying properties, and has the effect of shielding ultraviolet rays (UV) (UPF30-50+), preventing skin from showing through and preventing skin chafing with board shorts. Also, with a special sewing machine, the seams are sewn flat without edges, reducing stress on the skin. They are boxer shorts-length, can also be used as sports undergarments, and feature a logo waistband that is visible as an accent. 【UV PROTECTION】 UPF stands for UltraViolet Protection Factor. It is a global standard for UV protection established in Australia/New Zealand, and it quantifies how much UV rays can be blocked. The UPF value is based on the amount of UV rays that would cause the skin to redden in about 20 minutes without protection. For example, UPF30 means that it prevents sunburn for 30 times longer. UPF15 or higher is considered "good," and products with UPF30 are "excellent," and UPF50+ (plus) are "very excellent" in preventing the effects of UV rays. ■ Product Details ■ 【Item No.】BD011491 ■Color: STH (Smoke) ■Size: S (Waist: approx. 58cm / Hips: approx. 80cm / Front rise: approx. 24cm / Back rise: approx. 28cm / Inseam: 19.5cm / Thigh width: approx. 23.5cm / Side length: approx. 33.5cm) New, unused, and unopened, but the package is deteriorated and has scratches.
