We worked hard on this one. We got alot of input from some long time sailors on what they want from a kit bag.
We have a few things that you cannot get in any other bag.
We added the mesh vent on one side to let foils dry and protect from overheating. Our bag is padded throughout. We include a flat zippered pocket for battens and lines so they are easy to access. Velcro flap covers the padded rudder compartment and a full length mesh pocket that can fit a folded sail. Tiller and rudder tube is on the other side. We also have an oversize 3 sided coil self healing zipper for the board compartment.
All this with a shoulder strap and carry handle.
You can find other bags but you will only be paying more!
