This Nalgene bottle holster is high quality. I put mine on a exo K4 3600 pack. I like having designated places for gear organization so this is a no brainer. The cinch down cord works great to keep your bottle from dumping out while you creep up on your prey. There is a whole in the bottom for drainage as well. This pouch can also be used for saddle rope storage or for extra handy stuff. The durable material should last many years.
