The Fly High Pro X Series Rear Seat / Center Locker Sac is a versatile wakeboard ballast bag that works well in place of the rear seat on inboards, in the ski locker, or anywhere else it fits.

The Fly High Pro X Series Center Locker/Rear Seat Sac is one of the most versatile wakeboard ballast bags that Fly High currently offers, finding a perfect home in many locations throughout the boat. Its low profile design means it will fit in many storage areas including the center locker, under seat storage, or in place of the rear seat, yet the generous length and width add up to allow a significant amount of additional weight.

The Rear Seat Sac is designed to replace the rear seat cushion in direct drive wakeboard boats with 580lbs. of ballast. Thanks to the bulletproof construction, sitting, standing or walking on the bag is perfectly fine.

Also fits well in the center locker location on both inboard and I/O boats, making this a great option to get the all important bow weight.

What Fittings Are Included With This Bag?
This Fly High Pro X Series wakeboard ballast bag includes the necessary fittings for filling and draining using a portable wakeboard ballast pump; you do not need to purchase anything else.

Optional fittings are available to make the filling and draining process more convenient, see recommended accessories for more information. This wakeboard ballast bag can also be used in an integrated ballast system which requires additional wakeboard ballast fittings. If you have any questions please contact us.

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.

    I'm crazy about this bag!

    It says 580 but I bet I have it pumped to about 650. I love this bag form any reasons. Mainly it fits super snug in the ski locker of my 2000 Super Air Nautique when pumped extra full. I upgraded from a 360 bag, and I am so impressed with the difference in this bag for that space. I also love when paired with a Tsunami portable pump, it sucks nearly every drop out of the bag. Plumbed automated pumps to come later on. Also, they smell real nice out of the package.

    2006 MasterCraft X30 replacement KGB

    Needed a bag to replace a damaged hard tank KGB. This bag is a little too big but looks to be the only pre-made bag that will use close to 100% of the available space. After the initial install it was pushing up on the access door and the 4 screws that hold it weren't going to hold it. Engineered some support that takes the weight off the door and it works great now.

    I think the Fly High bags are tougher than some of the competing bags. One other brand has plugs that are too flat and near impossible to loosen with your hand. No such issues with Fly High.

    I used this as a rear seat in the back of my DD 205 and am a little disappointed. Have had issues with the most frequently used fittings, mainly the fill port, threads not resting in a sealed position. The fitting are prone to over tightening if you are not very careful and it has started to strip the treads of the bag. I have stopped using this bag and replaced it with another manufacturer with a 1 inch fill port. The 3/4 port really is that restrictive comparably. I'm sure for a Stock replacement that was already 3/4 this is fine but for me it didn't fit the bill. Decent bag but not reliable as I would have liked.

    05 Sunscape Ski locker

    Have this big boy plumbed up permanently in floor ski locker. I was after a bag to fill this space which is does well, only problem is fill / vent outlets on top pushes on lid when taking off.(Wakemakers advised next size down) I have made some changes and all sweet but one more fill / drain out-let on end would be better value.
    Bag is strong as, wake is big as... Happy rider.
