i have been using this bag exclusively as my daily use bag, i ride a motorcyle 7 days a week year round in florida. It is rarely not on my back thru out the week. Worn it in hurricane weather and 100+F temps. It was even on my back buring a 30mph bike accident (only visible wear is on the mesh side pouch that hold the waist strap when not in use) i use it for everything from holding rain gear to transporting groceries. Tons of pockets of all shapes and sizes.
Pros: easy access to gear w/o removing the bag, lots of pockets and attachment options
Cons: shoulder strap create a sweat area on chest/shoulder and can fatigue back on one side when used long term fully loaded
