Replacement or extra internal dry bags for the Cargo Fly system. The Standard Dry Bags have a Ti-Zip closure and and inflation tube, which allows them to act as secondary air chambers on river systems with multi-chamber permitting requirements. The Ultralight Dry Bags are half the weight of the Standard Dry Bags and have a standard roll top closure. Both versions clip into place along the sides of the packraft with a quick release buckle.
When packing your Cargo Fly Internal Dry Bags, distribute the weight evenly between each bag and make sure to pad any hard items (pots, stoves, etc.) with clothing and keep them towards the inside and top of the tubes to avoid pinch flatting the packraft in shallow rivers.
