The Exped Ultralite Compression Bag is a totally waterproof bag ideal for the fast and light adventure racer or backpacker wanting to keep clothes or a sleeping bag dry and compressed, taking up minimum space.The Taffeta nylon is PU coated on the inside and Silicone coated on the outer along with fully taped seams, keeping your contents inside dry. It is quick and easy to use by stuffing your clothes or sleeping bag into the bag and then pulling the compression cords tight, then roll the closure down and snap the buckle closed. The compression cords are across the bag to enable access to the contents when compressed and with a base counter grip the contents can also be easily removed. The flat valve enables you to get all the air out of the bag to enable greater compression.
