Perfect for the treehugg'n hiker or environmentally conscious outdoors person, the ECO Pneumo's have all the tough features of our LTW Pneumos but with a twist. Non-dyed, single coated bamboo based fabric keeps your gear dry and the recycled aluminum purge valve allows them to be compressible in three useful sizes. If that's not enough, we are purchasing wind energy we've offset the carbon footprint created in the production of these bags.
