I just recently started using Livingstone’s 25L Alberta pack and so far love it for day hikes. It’s super light weight (0.5lb), comfortably sits on your shoulders, and both the backpack material and zipper lining is waterproof. When you’re not using the pack it easily folds up into a little pouch for easy storage. It has one large pouch, one smaller front pouch, and two side pockets for water bottle storage. I like that this backpack is lightweight and not bulky. Added bonus, for every backpack that’s purchased Livingston makes a $1 donation to the national parks in both the USA and Canada.
