This bag facilitates enormously the storage of the main sail on  the boom. The lazy jacks that keep raised the bag, are forwarded at the deck, to get them lowered without altering the main sail shape, to keep the boat cleaner at the time of competing.

The new lazy bag generation combines efficiency and elegance. Made of diverse colors acrylic clothes.

Once the zipper is closed, a second bag finishes off at the mast and definitively the main sail. The fixation to the boom is with slides, without holes nor complicated iron-works.
