A very lightweight compression bag with strong webbing and buckles. Available in two sizes. Likely a one-off batch, act quickly!
Packing your gear in separate bags makes a lot of sense. If the piece of kit happens to be compressible (down jacket, woobie, sleeping bag, hammock quilt...), make use of it to save space!
These bags are made from durable ripstop nylon with polymer buckles and cord locks. Reinforced at stress points with a webbing band running around the center to ensure you can really push the fluffy stuff in and chinch the straps down good without ripping the bag apart. Still very lightweight to keep your kit from becoming a burden.
These are surplus items that have not been used, the condition is virtually new. At most, you may see signs of storage.
