My Take On It
YOU MUST WORK FOR KLIM. GO FIGURE
"HandFullThrottle" does not work for Klim (I asked everyone in the building) but I do.
He is correct however.
We did try Event, it had a propensity to delaminate, tear, fracture, pinhole, and altogether fail in a short period of use. It MAY hold up OK in another application like skiing, but it does not hold up to the abuse snowmobiling provides.
At the OR show in SLC there were some ski companies using a demonstration that forced air through Event membrane from below and you could watch it bubble through the water on top. This was supposed to demonstrate breathability. What is being demonstrated is that Event is not 100% windproof.
Finally Event does not hold seam tape well; it peels and opens the seams to water intrusion.
It is Gore-Tex that NASA trusts to provide material for their space suits.
Chemical and biological protective suits are constructed using genuine Gore-Tex materials. Imagine the trust needed to walk into a hazmat situation.
If you were to have your Aorta repaired it is a Gore-Tex product being used.
I am not going to stand in line for a vascular graft if they are using Event. And if I would not trust my life to it in that scenario, why would I trust my life to it on a sled trip gone wrong?
If it has to be trusted, to be windproof waterproof and breathable; and to remain that way far into the future- in our experience, it must be Gore-Tex.
Gore undeniably stands behind their product offering the "Guaranteed To Keep you Dry" Promise. I have seen them stand behind that promise with certainty, most recently a Search and Rescue volunteer from North Ogden, Utah with TEN year old bibs.
We are not compelled to use Gore-Tex, we choose to do so because we trust it.
92% of all Iron Dog racers trusted some Klim product in the 2010 race. To my knowledge we didn't let any of them down. We don't intent to.
Quality is not ingredient only, it is a process. But why start a quality process with a compromised ingredient?
This is just my thoughts and experience. Perhaps one day there will be a membrane superior to Gore-Tex. It just isn't today.
See attached images. Six samples exposed to wear simulations; each one is comprised of Gore-Tex on one side and Event on the other.
