1978...W.L. Gore invented Gore-Tex. I could go into the science of it all here, mentionning surface energy, surface tension, microns and pores per square inch or metre but basically all you need to know is that this man-made fibre has microscopic holes in it that big waterdrops can't penetrate while small water vapour moisture drops can. Meaning big raindrops on the out side stay out and tiny moisture drops on the inside, created by you, can escape, thus keeping you dry.
Roof crush injury risks are higher in vehicles with a greater propensity to roll over. Because they are taller and narrower, SUVs, or sports utility vehicles, are three times more likely to roll over in an accident than are other passenger cars. In 1973, the government passed Federal Motor Vehicle Safety Standard 216, creating a standard roof strength test to measure the integrity of roof structure in motor vehicles. This test was to apply to motor vehicles weighing six thousand pounds or less. Many SUVs weigh more than this, and are therefore exempt from compulsory safety standards that may be crucial to preventing roof crush injury. In light of SUV roof crush injury risks, consumer advocacy groups have urged the federal government to modify standards so that they include any vehicle weighing ten thousand pounds or less.
Because the vehicle has changed from simply being an off-road vehicle to a replacement for the family station wagon, manufacturers removed the roll bar that protects drivers and passengers in a rollover situation from SUVs. Many SUV rollover accidents occur because of the unusual propensity the large car has to roll over when steered hard in foreseeable accident avoidance maneuvers. Also, the size and height of an SUV may increase the danger of rollovers. SUV defects, like weak roofs and safety restraint system failures, are some of the heightened risks involved in an SUV rollover situation. Roof Crush Injury
