I got this to replace a chrome backpack I bought 10ish years ago that finally was dying after some rough love. I was worried this bag would be too big for what I needed (but thought the smaller would be too small) but I was wrong. Its perfect. Its already protected my stuff through some summer downpours and on sweltering humid days it hasn't felt too sweaty (thanks to the nice back pads). The straps took a few weeks to break in but are just fine now (start a bit stiff because. Well. New product). I added some packing cubes to increase organization on the inside, and sort of wish the inside organizer had a velcro or zip top to keep things from falling into the main bag when I lay the backpack down. But otherwise I love the heck out of this bag. Also- I did settle for red as none of the colors were my speed. I wanted visibility and bright but don't love red. But Chrome seems to be the only waterproof backpack on the market that doesn't look like a backpacking or elementary school bag. Luckily, the bag functions great.
