QUALITY TESTING
CRUMPLE TEST
An extreme test of GORE-TEX® fabric’s waterproofness
Leakage after cold flex can be a significant problem with many fabrics: they can crack under stress, especially when exposed to sub-freezing temperatures over a period of time. In the Crumple Test, GORE-TEX® fabrics are squashed and stretched repeatedly in extreme temperatures for hours on end. The fabrics must survive this punishing test and emerge still durably waterproof.
