Orange Mud HydraQuiver Double Barrel
Here's what other sites are saying:
The Orange Mud Double Barrel pack has been upgraded for 2014. The shoulder pockets were changed to an expandable knit, and the closure is now an ultra soft medical grade neoprene. The rear expandable pocket is now gone and in exchange has a lash down area in between the bottle holders where elastic cord and a cord lock will be to hold down your jackets and such.
