I’m not so sure they are actually “the first”. Dorsal has a product line with 100% recycled material as well. No big, any effort toward recycling is a winner in my book!
It’s really cool to see the responsibility fin manufacturers are taking while offering high performance quality products. If you check out the Dorsal site (they also have a Facebook site) you’ll see they did a full line of tri, quad and single fins in 7, 8, 9, 10, and even 10" & 12" hatchet fins. They are clear, red, blue and black with varying degrees of flex.
They are getting ready to do a run of stiffer fins than their current “medium flex”, which I think are good for lighter riders up to 160 lbs. on HPSB’s but need a stiffer option for the big boy tri guys.
I am sending them some plans to add fish fins to their line as every fish fin I’ve seen cost an arm and a leg!!!
