Aerospace Tek  

Aerospace Tek is a very smooth feeling non-stretch woven.   Its a strong yet lightweight fabric that is moderately water repellent and extremely wind resistant. It's not considered highly breathable, so is best for leisure rather than highly aerobic activities.  Aerospace Tek is an ideal fabric for making super lightweight/packable windbreaker jackets or vests.  It is also useful as a smooth lining for garments, especially if you wish to make them windproof. 

Several customers have used it to make water repellent drapes and shower curtains, although it is definitely a lovely apparel fabric.
