    Expert Review

    My favorite pack. Carried this for all of Cocodona 250 and all three days of Three days of Syllamo as a train up. I cannot say enough positive things about this pack. It's comfortable, accessable, useable, and useful! Easy access to all pockets on the go without being a contortionist. Large dump pockets along the sides with drawstring to keep stuff in. Carries a lot of water comfortably! Love this vest!
