Grayman and 4GF have teamed up to produce "Blue Streak" mats...which are 4GF models made with thin, blue nylon twill (100 denier x 70 denier) on both top and bottom. This combination provides a delicate, zippy ride.
G-Man has developed a traction system that's really good...soft to the touch, but grippy and durable. I'm shipping him smooth-decked 4GFs and he's customizing them with his deck.
Details on the new Blue Streaks -- and how to make a purchase -- are
here.
It's important to point out that the Blue Streak concept is nothing new, as 4GF and Neumatic rafts have used thin material on the decks for many, many years. It's simply an alternative to the heavier nylon canvas decks currently used by 4GF. The canvas decks provide a comfortable and easy-to-use topside that harkens back to the old days of cotton canvas surf mats. They are super-fun to lie on, and easy to move around on when riding a wave. They also provide more mass when riding big, bumpy waves. Both George Greenough and I use the canvas decks exclusively and love them.
So...view the Blue Streaks as an option that can and will widen your mat riding horizons!
