At U-Stick our kite bladders are custom-made and we offer a wide variety so that we can deliver the right size bladder for your personal item, whether that is a Kite, Wing or Custom Inflatable!

The materials we use are only of the highest quality. All our bladders are made of a qualitative Polyurethane material and finished with the original valves of the brand itself. All valves are glued on the material to ensure the best connection between bladder & valve for the longest time possible.

Valves and Repair Accessories

At U-stick we have a lot of stock for all kinds of Kite & Wing brands. We have all valves available as RAW and as Repair Kits! All valves are original.

Leaking valves will ruin your kite session and buying a new bladder can be quite expensive. That is one of the reasons why we also offer several Valve Repair Kits with a strong adhesive backing, so that you can easily replace the valve yourself. 


Is your valve is still in good shape but isn’t sticking to the bladder anymore? Take a look at the Valve Trap. With the Valve Trap you can easily re-use your old valve. Are you looking for different materials to repair your kite? Take a look at our Kite Repair Accessories.
