Miranda (who does REI YouTube videos) interviews GORE-TEX rep who explains why you should wash (and more importantly dry in a dryer) your GORE-TEX clothing.
Thanks for sharing this video. Now I have to find some of my “worn out” gortex gear and see if I can resurrect it. I have been washing by hand with the nikwax and it never really seems to bring it back to life.
just washed my simms jacket today, which has Gore-Tex. I was reading the tag and it says right on there to tumble dry low, and then put it back in for another 20 min after the first cycle to re-activate the Gore.
I remember listening to Barklow from Sitka about this on a podcast. He also said oils from your skin, dirt, bug spray do WAY more damage to the garment (and reduce it's effectiveness) than washing ever would.
Something Goretex used to say all the time. Though the amount of heat that's safe to use has decreased with the thermoset applied details on some garments.
