A buddy ruptured the bladder in his Naish wing and was wondering if anyone could help.

He's looking for patches, maybe an old ruptured bladder someone might have that he could cannibalize for material?

How big of a hole in the bladder? Duotone wings ship with Park Tool's GP-2 patch kit for bicycle inner tubes - https://www.parktool.com/product/super-patch-kit-gp-2. I've used Tear-Aid Type A on a kite bladder pinhole - https://www.tear-aid.com/ . Standard kit comes with one 3"x12" patch, plus a couple of smaller ones.

Thx, he got it sorted out.
