I pulled the stock rear Fat Sac's early this season (practically brand new) and replaced with larger sac's. They have been stored with care inside my house.
These are the custom, mesh, high quality, durable 250lb Barefoot Intl Fly High Fat Sac's that are special made for Moomba/Supra's Bertha Ballast system.

I am willing to sell them both for $175 plus shipping. Of course, I am open to offers. Please email me at 'boatnuts@hotmail.com' if you are interested.
