The chair's lightweight yet durable nature comes from it's use of 7075 aircraft aluminum for it's frame poles. The poles are fitted with elastic shock-cord inside allowing the chair to virtually assemble itself. This self-contained pole system also ensures no poles are left behind. Breaking the chair down and packing it away in it's stuff sack is just as easy as assembly. Easily packable and weighing in at just under 2 pounds, the ONWEGO® folding backpacking chair is ready for any adventure you throw it's way.
