The HAWG is the best, most durable hydrationpack I have used. It is big enough to load in a windshirt or top, tools, 100 oz of h2o, phone, light, pump/co2, and, of course, hammergel. Totally the way to go if you are heading out for a long ride.
My daughter will love this pack. Nice and handy...
i have this pack for 3 yrs now. i like a large pack to hold more items, like extra tubes, a windbreaker, a pump, gel packs, energy bars, CO2 cartridges tool kit and of course the 100oz bladder. I like the way it snaps at the top of your chest and along the waistline, making it a very secure fit. I like it so much that 2 of my other friends bought the pack.
Essential for walks,hikes,10 k's or even walking to or frome school.. it will alays keep you hydrated and refreshed. great item to have. dont go trvaling with out it...
