I have a drinking problem. If I’m running on trails in the woods, water fountains aren’t exactly plentiful. I don’t want to hold onto anything or wear a dorky hip belt, so how do I obey my thirst? Thankfully, I found out about the Osprey Rev 6, a super-lightweight hydration pack made expressly for runners and cyclists. What makes it a no-brainer for trail running in particular is the hip stabilizers: They’re large and pliable enough to wrap around your flanks almost like a shirt, which means zero bouncing. Even better, the re-designed hydration bladder is easier to take apart and clean without spilling water all over yourself.
