This product was everything I was looking for. I'm very impressed with the quality and sturdiness, I expect it will last a long time even with the heavy use it'll get. This pack holds enough water for my outdoor adventures and has just enough spare room for my snacks and miscellaneous items. I took it cross country skiing for its first outing, and it held enough water for my trip, a snack, an inhaler, my small sketchbook, a watercolor brush, travel paint pallet, and pen for a quick field sketch. Bonus - I can thread my bear spray through the belt strap so that I'm prepared in the event of wildlife run-ins. I'm looking forward to using the heck out of this pack to encourage constant hydration while at work in the woods, on bike rides, runs, etc.
