These Osprey backpacks are the best backpacks you can buy. Sure it’s not the flashiest and may not have the most pockets or features, but it’s got it where it counts. Lifetime warranty. LIFETIME. On a backpack? That’s unheard of. Most usually come with a Camelback as well, along with rain cover that is stored in the bottom of the bag with an easy access pouch, making it a 5 second change into a waterproof backpack.
