I received my Recycled Waders nook sack today and I have to say I'm impressed with the quality. JB asked if it would hold a nalgene bottle so I put a 2.5 cup bottle in the bag and it took up basically half the bag, so if I were to carry a water bottle it would be like I thought, a water filtering bottle. That way I could have as much water as I need, but not have to carry the weight of the water all the time. The Nook Sack, a bottle for water, and a net is all I'd need for a day on the water. You could take a Camel Back for water too if you didn't want to use a filtering bottle. I'm trying to get the gear down to a minimum as much as possible.
