Patagonia Black Hole 25L Backpack-Abalone Blue

This is a great daypack for daily use or day hikes. I like the pockets inside, one for your laptop and a secret zipper pocket, in addition to the main compartment. The pocket on top of the bag is easily accessible. It has a chest strap but does not have a waist strap so best for packing for short day hikes. The waterproofing is great so you don't have to worry too much about your items in side if you get caught in the rain!
