This is quite a different product from a membrane sail.
The membrane technology is basically a paneled sail that has seam shaping in the Batten pockets and is then glued and sewn, each panel is produced to be as light and as strong as needed.
A 3Di sail is made on a shaped mould, so the sail shape is moulded. Then fibres are laid head to clew etc and they follow the mapped capillary lines covering the whole sail in a continuous pattern. This is a way more superior process.
I hope for North sails sake they do well but really don't see the personal service like you get from Ezzy ever happening.
Probably great for lighter riders.
Not sure how the Ozzie summer heat will impact them.
Kiteboarders selling sails ?????
The Picture below is of a small yacht membrane sail before its glued together.
