Review on Gregory Mountain Products Hydration Backpack Sports & Fitness by Nigel Cohen

Such a solid backpack. No rubbing or tingling. This keeps my back cool and comfortable in all conditions. Lots of space inside, practical side pockets for water bottles. The bladder is my favorite because even when new it had no smell or taste. You just have to make sure the mouthpiece is turned the right way so you don't have magnet problems like other reviewers. Maybe they updated it? The only downside for me is that there are no hooks/tabs in the packaging itself and the ones on the strap itself are so high that they are a bit tight around the neck/chest. All in all a great bag for all day or light night use.
