The Gossamer Gear Kumo Superlight backpack is a tough, smaller volume pack that is loaded with new fabrics and features.  Built on the old Murmur platform but constructed largely of our custom 100d and 200d Robic fabric. The Kumo was named in honor of our great friends and customers in Japan as well as to describe the pack itself. Kumo is Japanese for "Cloud", and can also mean "Spider".

The Kumo continues the use of our OTT (Over-the-Top™) closure system with an added zippered pocket there for quick access to vital goods.  Both side pockets are constructed of our Robic fabric to minimize snagging and increase durability. The big back pocket in made from our power mesh with a new angled top to allow easy access. We have opted for a 1.5"  webbing for the removable hipbelt for solid weight transfer and load control. The Kumo also features our new more ergonomic shoulder strap harness and a EZClip sternum strap and accessory mounting system. The Gossamer Gear Kumo also sports a lashing system for squeezing and hanging your gear with.   As always there is a pad holder pocket on the front that will accept the included Sitlight as well as many other pads.

We also offer a belt with pockets that can be purchased as an add on for this product.

We recommend the Kumo SuperLight backpack for total weights below 25lbs. Recommended uses are backpacking, dayhiking, travel (can be used as a carry-on bag),  mountaineering and any other appropriate adventure.
