We were fortunate to receive the brand new Helite Turtle 2 on loan from Helite to test. It was too big for me, so I didn’t ride-test it, but I did get to try out detonating (is that the right word?) a cartridge while wearing it. It really does provide nearly instant neck stabilization and after this test, I’d be very confident in it protecting me when I really needed it to.
You should definitely read OnlyTwoWheels’ full writeup. I’m putting one of these (in the correct size) on my Christmas list for sure!
Check out the video – the eyes have it!
