Fit Egg likes the Avila Hydration Pack, our littlest pack. They note the lightweight minimalist pack was perfect for shorter 5K to 10 Mile runs. One note of worry was that one of there testers who was 6’2″, 240 pounds, and had a 48″ chest found the chest strap a little small….I’ll bet he’s run into that problem before.
They also noted that “The first thing testers noticed about the pack is that it’s lightweight, especially when you consider the liquid volume it carries and the available storage space for other goodies like food, gels, and cellphones. In addition to being light, the back is well ventilated. Shoulder straps are mesh and the actual pack footprint is small, so there’s not a lot of material to trap heat. The Avila is designed as a minimalist pack and it is.”
