Thank you for viewing. Please read the profile before purchasing ◡̈♥︎ This top was purchased from SeaRoomlynn. Brand new, with tags. Color: Apple Size: FREE 【Simple, Uncluttered Design】 To avoid being bulky as an inner layer, we've kept the design as simple as possible, without adding ribs. The binding is also slim and neat. The heathered colors are cute even when worn alone. ◆Coordination Suggestions Please use it as an inner layer for knitwear or sweatshirts. You can also make the long-sleeved T-shirt the main focus by pairing it with a cardigan. ※About HOT HOUSE ◆Characteristics The fibers absorb moisture emitted from the body and generate heat. (Heat is generated when moisture is absorbed onto the fiber surface and kinetic energy is converted into thermal energy) The amount of heat generated is about 3 times that of wool, and it also releases moisture at high speed. ◆Principle It applies the mechanism by which mammals and birds generate heat when their fur (feathers) absorbs moisture. ◆Functions In addition to the moisture-absorbing and heat-generating properties, it also has functions such as deodorization, flame resistance, and antistatic properties.
