At approximately 20gsm to 22.5gsm this lightweight covering material is ideal for the UMX glider range, along with the Pug DLG and Pug Twisty.
What makes this material especially suitable for the UMX gliders is its moderate shrink compared to traditional iron on coverings. This makes it easier to cover these lightweight delicate structures whilst minimizing the chance of inducing warps.
The finish is either reminiscent in appearance of doped tissue or a totally transparent plastic film that catches and reflects light with a shimmer.
