Packs that give your body what it needs!
Today's hydration packs and fanny packs give you what your body needs, plus a little extra depending on your activity. If you're biking, for example, the Osprey Raptor 10 backpack offers a streamlined pack for your water and bare essentials - plus a helmet holder for when you make it to the top. A backpacking summit ascent or day hike might require an Osprey Manta 28 because it has that extra space for another warmth layer and food.
(Please note most day hiking backpacks are hydration-compatible, all you need to do is add a reservoir of your choice. Check out all of our backpack offerings for longer trips and extra capacity.)
