Although there is nothing like a heavy absorbent bathrobe on cold winter nights, lightweight robes belong in your wardrobe, too. Whether knit, slinky satin, or woven, a lightweight robe provides a modest cover up while still flattering your curves. Lightweight robes are perfect for travel. With modern nylon, polyester and other synthetic fabrics, a lightweight robe is easily folded and packed. Unpack, shake it out and your robe is ready for relaxing after a long day or answering a knock on the door.
