Review on Gregory Mountain Products Hydration Backpack Motorcycle & Powersports ~ Accessories by Erik Snyder

I was specifically looking for backpacks with magnet attachment to hold the tube on the front straps so I gave this backpack a try. I like the size and pockets/features of this backpack, but the magnet feature doesn't work as well as the osprey. Looking closer, I noticed that the Osprey packs have a rotating part so the magnets still stick when you move. This makes it rigid, so the magnets can come loose with a small movement.
