Pack perfection

  • Familiarity: I've put it through the wringer

I love this pack. I use it more than any other hydration/pack system. It's the perfect size for an all day adventure or long endurance race. I've ran 100 miles, moutain biked 15 hrs & competed in a multi sport adventure race using it. It's large enough to hold extra clothes & enough food & water for a long day in the mountains. I love the front pockets. There's a zippered one as well as two drawstring pockets in front, great accessibility. It's very easy to adjust the length & tightness of the pack, making it feel like it has a custom fit to each person's body. I've never had issues with chaffing or feeling uncomfortable in it. Durable materials take a beating also. I got a little creative and customized mine. highly recommended.
