Lightweight and quick-drying, this versatile underwear performs well in all seasons, from intense, sweat-inducing workouts in the cold season to watersports in the summer. It has a soft texture with minimal compression, providing a comfortable fit that reduces stress. Excellent absorbency, wicking, and odor-resistant properties. Specifications: 【Material】Geoline® [100% Polyester] 【Average Weight】120g 【Color】Black (BK) 【Size】M 【Features】Spiral Slantec® Cuffs / Flat Seams / Long Tail Design The size logo is faded, but it is size M. There is some wear and tear, but there is no major damage, and I think it can still be used sufficiently. It is thin and warm, and can be used for a long season. Thank you.
