Yamato Michi Alpha Socks Alpha Socks I purchased these new and have stored them at home. I have kept the box, so I will include it, but the outer box has some scratches from storage. There are no noticeable scratches or stains on the product itself, but please refrain from purchasing if you are concerned, as it has been stored at home. I will ship the item by Nekopos, with the shipping label attached to the outer box. Below are the product details: Color: Yellow Size: L (Foot length 25.0-28.0 cm) Weight: 38g Material: Polartec Alpha Direct (100% Polyester) 136g/m2 Lightweight, non-sweaty socks for sleeping These socks use thick Polartec Alpha Direct, which offers an excellent balance of breathability and warmth. They are lighter than down socks, moderately warm, and comfortable for sleeping without causing sweat. The socks have a wrap-around fit that doesn't constrict the ankles or heels, gently protecting hikers' feet from the cold until morning.
