Review on Stansport 20L Hydration Pack with Water Bladder by Peter Zouhair

I wanted a small backpack to use on my afternoon bike rides through the woods. However, I like the overall look and fit of the backpack. The way the pack assembles when you add gear takes up space in other storage spaces, leaving you with very little storage space. Much less than advertised. I'm not sure if it's a second or something. Most backpacks expand as you add gear, this expands and significantly reduces overall space. I can barely store my tools and first aid kit. I could get a sandwich. I couldn't use hard shells for anything because too little space was added for something. It seems to work for my needs, but imagine replacing it next year.
