Well loved but still looks new. Super lightweight, pack able but very warm-worn throughout a cold winter in Eastern Europe. Re:Down Sleeping Bag Puffer Everlane also released their Re:Down line this fall. Oh sorry, Re:Down®. The shell is 100% recycled polyester while the interior is 100% recycled down from comforters and pillows. All in all, 18 plastic bottles go into making the Re:Down Sleeping Bag Puffer. It’s water-resistant, machine washable, and suitable for temperatures of 10 to 30 F. Here’s the 5′ 8″ model wearing a S. As you can see, the fabric has a slight sheen to it.
