I had the same thing happen to my Halcyon Evolve wing. The stitching came off the exterior bag. I called Halcyon and they told me to send the outer bag and they'd send me a new one. Instead, since I was going to be in High Springs cave diving, I took the wing with me. Not only did Halcyon replace the outer bag, they gave me a brand new wing on the spot. That's customer service!
That is exactly why I buy everything from Halcyon.
