These amphibious inner pants are lightweight and highly stretchable, preventing chafing and making them ideal as underwear. The slightly longer length above the knee and the stretchiness mean you don't have to worry about them riding up during exercise.

Please choose sports innerwear that fits snugly. Made from the same thin material as rash guards, they are easy to layer without feeling bulky. The wide waistband also provides comfort even during intense upper body movements. Not only for field sports, but also as innerwear for surf pants and wetsuits, they are an essential item for marine sports. By wearing inner pants that are almost the same length as your surf shorts, you can achieve a stylish look. The black color makes it easy to coordinate with your favorite pants. The brand mark printed on the hem is also a cool detail.

【Benefits of Innerwear】
