This backpack is made of a material called Spinnaker, which is a fabric that is used to make balloon-like sails. It’s super light-weight and thin. When you carry this backpack empty on your back, you won’t feel the weight but only the fit of it. It has a storage bag inside, and you can fold the backpack small enough to carry it in one hand. The zig zag pattern represents the “marine-goods stitch” that appears when you sew sails. The spinnaker cloth is waterproof, so no worries for slight rain! (The sewn parts and zipper are not waterproof)

This backpack is more suitable as a sub-bag to use when you go for walks or trips, rather than for full-fledged outdoor activities. Since the backpack itself weighs almost nothing, it’s perfect to carry small personal items during your morning jogs or walking your dog. Also, if you have this backpack packed in your carry bag, you can pack the things you need while on the plane, or use it as an extra bag to pack souvenirs when your suitcase is full after a long trip.
