Fly High FATSAC ¾” Ports

¾” Port Size for Speedy Filling/Draining

Fly High Pro X Series wakeboard ballast bags were the first products designed from the ground up to be used in a wakeboard boat. Starting with a blank canvas, Fly High was able to rethink nearly every aspect of wakeboard ballast bag constructions and functionality. Gone are the day of two-part construction, leaky waterbed connections, and fittings that are difficult to connect. By building their wakeboard ballast bags from a single layer of durable yet flexible vinyl, the same material that is used to build white water rafts, Fly High is able to offer unmatched strength and durability in an easy to use package.

Additionally, Fly High Pro X Series ballast bags feature multiple threaded ports that are built into the construction of the bag. Unlike the blue waterbed connections use on other brands, these strong ports feature durable threads and can be used with Fly High’s options fittings for compatibility with nearly any wakeboard ballast system you can imagine. Step up to the Fly High Pro X Series wakeboard ballast bags and experience the most convenient, durable and highest performing ballast bags on the market.
