Kushitani Mid Inner Bottoms High-Function Innerwear Model Number: k-1331 Color: Black Size: XL Retail Price: 16,280 yen (tax included) Purchased from Kushitani Online. The tags are still attached, but it's a new, unused item, only tried on. It has been stored in a closet. I'm selling it to someone who needs it, as I haven't had the opportunity to wear it. The following is quoted from the manufacturer's website: Inner pants made of a slub-patterned windproof material. The material's stretch and three-dimensional cutting provide high mobility. The inner thighs, back of the knees, and hem are switched to a 2-way knit to reduce stress. ●Material: 100% polyester (breathable windproof film 3-layer), separate fabric/84% polyester, 16% polyurethane (windproof film 3-layer) Thank you for reading to the end.
