The Gowiss backpack is extremely compact and able to be folded completely inside of its own inner pocket. Once unfolded it looks like any other backpack as far as shape is concerned but is much lighter than most thanks to its lightweight yet durable material. The straps are fully adjustable and should have no problems fitting anyone from a kid to an average sized adult easily.
Thanks to its numerous pockets it is easy to organize things in this backpack. All pockets feature waterproof zippers that do a great job of keeping the water out.
If you are looking for a lightweight backpack that is small but will still hold quite a bit at a decent price, I highly recommend this one.
