Ergodyne Chill-Its® 5157 Premium Cargo Hydration Pack, Black, 3 ltr

Let's start off with the negatives. The smallest, upper-most pocket stitching came unraveled within 24-hours of me loading it with only 3 CHILL-IT'S. No need for the zipper on that pocket anymore. I'm pretty sure my pack was just a fluke- all other pockets are holding up great. POSITIVES:The tube is insulated, adjustable shoulder straps, very padded back, multiple storage compartments, headphone cord outlet so you can have ipod or mp3 in your pack. I'm used to having a 3L pack but this 2L pack is great. I've left it outside in my car EVERY night....Michigan is COLDDD right now. I have water bottles and soda cans frozen in my car but this hydration pack has never frozen - beats my buddy's ""military issue"" camelback that doesn't quite stack up to the Tenacity of Ergodyne's very comfortable to wear, shoulder and waist straps help keep it snug to the body - those are also removable which is pretty cool. Other than the stitching on the small pocket this cargo hydration pack has been awesome. Hydration + Storage - It's the best of both for staying Tenacious on the job!

I used this for trail hiking, in total I hiked just shy of 16 miles in 95 degree weather. This thing was very convenient and because it's small and sits up high on the back it was never in my way. Pockets to carry, keys, cell phone, and snacks. Would definitely buy this again. [This review was collected as part of a promotion.]
