I purchased this from the sports shop Alpen about 3 years ago. I found it very useful when I first started running, but as my level increased, it became too hot to wear, so I'm selling it. I've kept it in a garment case for the past two years. It has been home-laundered. Since it is a used item, I've marked the condition as "has some scratches and stains." We have no pets or infants in our home. Instant purchase is OK! The following is a product description (quoted from the HP): ■ This thermal innerwear uses the moisture-absorbing and heat-generating material "iHEAT" and provides +3°C of heat retention. It has the highest heat retention in iHEAT history (2.5 times that of the lightweight type). This iHEAT extra-thick type has stretch, anti-static, and deodorizing (deodorizing tape is used in some areas) functions, making it comfortable to wear. ■ Color: Black ■ Material: 64% polyester, 33% rayon, 3% polyurethane ■ Size: S size Height: 162-168cm Chest: 85-91cm #AutumnWinter #WinterItems #FleeceLined #HeatTech #Women's #Men's #Unisex #Unisex #Sports #Running #Loungewear #Pajamas #Underwear
