Review on TRIWONDER Outdoors Mochilas Marathoner Hydration by Chad Gravely

First impression is that I really like this hydrator. It has multiple straps to adjust the fit to keep it snug and prevent bouncing. I also love all the storage bags. I had to deduct a star (almost 2) for the hydrator. It is closed by folding the top down and then sliding a plastic clip down to hold it closed. The problem is that it is very difficult to "slide" on rubber with a plastic clip. I would have liked a screw cap filler neck like the Camelback. Update: Mea culpa. Upgrade from 4 to 5 stars. I folded the bodice wrong. Folding it in the right direction will make the clip easier to attach as there is a lot of plastic slipping on plastic. I wouldn't say it was "easy" though. Also advice. If you don't fill your bladder completely, make sure you try to get as much air out of it as possible before sealing it. This will help minimize "sloshing".
