These pants are made with Ariki's high-quality comfort and Mitsubishi Rayon's Soalon technology. This item is from a house clearance. I searched for the product number, but it seems to be a sold-out item that is no longer sold. The fabric is fine-grained and stretchy, and thin, so I think it's suitable for situations where you sweat, such as sports. You can wear it as bottoms on its own, as an inner layer, or as loungewear. The tailoring is solid and made in Japan for peace of mind. 【Size】 LL Waist (flat) 39 cm Rise 29 cm Inseam 58 cm Leggings Pants Trousers Spats Stretch Loungewear Workwear Office Casual Simple Black Black Elastic Waist Soalon Triacetate Sports Exercise New With Tags Unused Thin Sold Out LL XL Plus Size Ariki
