This is a one-off, handcrafted item. Please see the profile section. This is an UL-style napsack equipped with short shoulder harnesses (with 3mm cushioning), a shoulder strap using cord instead of a belt, and stretch cord. It's a simple packable design that can be stored in the pocket at the bottom of the back, allowing it to be carried in a compact form, making it suitable as a sub-pack. *The length of the shoulder belt can be adjusted with a cord slider. *The shoulder harness part of the shoulder belt is approximately 25cm long and only supports the upper part of the shoulder. Please be aware of this if you have a large build or if you want to use the shoulder belt in a long state. Please check if it reaches the top of your shoulder with your existing backpack, etc. Napsack / Sub-pack Packable (Simple type) Weight: 118g Flat lay: 27 x 55cm (when the drawstring is open) As shown in the photo: Approx. 23 x 45cm Bottom gusset: Max. 5cm (This is not the thickness when items are loaded) ★A pocket for a pad is attached to the entire inside of the back.
