The North Water Deck Mounted Water Bottle Holster is a water bottle holder that fits all size bottles from small 16 ounce (500 ml) to a one quart (liter) Nalgene bottle. The North Water Deck Mounted Water Bottle Holster is insulated with built in flotation, fits right or left of your deck, and attaches to your kayak by strapping to existing deck lines. After a long day of paddling, the North Water Deck Mounted Water Bottle Holster can also be carried as a waist belt so as to keep your water bottle close at all times. Bottle sold separately.
This is an excellent product. It's easy to install/adjust and fits my kayak perfectly. The insulation helps keep iced drinks cold longer.
