High Coast 24-Liter Waterproof Foldsack

I bought two, one for my UW kid and one for me. We love these packs. I use mine for my three devices. Two laptops and an iPad with my headphones, chargers and mouse. Not enough space for my keyboard but oh well. The pack is lightweight, no padding so my laptops are inside protector cases.

The bag is made with high-quality materials, and the zippers have worked well all the time. I've been using it for 3 years. It has two main problems: 1) The side pocket: if you have a slightly larger bottle, it doesn’t fit. If the backpack is already full, it’s impossible to put anything else in that pocket. 2) I’m not sure if others have the same issue, but I can’t use the backpack for more than 15 minutes without my back getting completely sweaty. I’ve never had this problem with other backpacks, but with this one, it’s impossible to avoid. I don’t know if it’s due to the materials or the design, but I always end up with a very sweaty back.

Fabric is flimsier than the original design of this style- it’s the only style that seemed to change- also the zipper cuts down on the height. It had more capacity with the extended top and drawstring. Curious why the design was not improved on instead? From this designers stand point - it seems there’s a lack of effort on quality.
