Hello, I wrote to you a fideback regarding your Shelter Backpack and the three other items I bought at the trustpilot review site. 1. The idea of the Shelter bag is amazing and very good! 2. There are some parts that need upgrading in my opinion: A. The side stretch straps for the main pocket should be different, they are difficult to fasten and release. B. The bottle pockets should be different - the mesh pockets seem to be less durable as you said, and the inner black pockets are not stretchable and unusable when the bag is full. c. The upper side straps are not fully understood - they seem to be in a bad position. d. The top strap for the main pocket is too short, it cannot be closed when the compartment is full. e. The lower flexible strap is too short, when I want to use it to attach the laundry bag or other things outside the bag. f. The main line should also match the side strips - the spaces between the seams should be equal. Other than that, the bag is perfect!
