Universal strut bladders with no valves attached. Purchase our U-STICK valves separately to assemble replacements for almost any kite ever made. Yeah....we invented 'em and we publish a handy dandy sizing chart for the most common kites.
Made right here in our own factory in the USA.
The bladders are measured from the head to tail in inches (we fudge a bit because we know the bladder can be longer but CAN'T be shorter than the original). If you have your bladder out measure head to tail and choose whatever size is equal or longer to your original (don't fudge on the measurement or you'll get yourself in trouble). Or just check the sizing chart, we probably list your kite.
We use only the highest quality US made polyurethane film for these bladders.. It's super stretchy, can handle abrasion, and moves easy when installing.
