As my knowledge about top-end gear has grown a couple of things have come to my attention that can have major impacts on the outdoor gear world as a whole in the future. 1. DWR issues 2. Polymers in the water supply 1. A couple years ago the latest and greatest durable water repellent (DWR) known as "C8 DWR" got banned from production due to negative effects on the ozone layer. C8 DWR has been replaced by C6 DWR. C6 DWR does not have as favorable feedback. I've read that these DWRs have a "radioactive half life" and that C6 DWR's "half life" is significantly shorter than C8 DWR's "half life". Reduction in "half life" causes it to loose effectiveness faster and get caught at reduced effectiveness more often. DWRs are incredibly important to the relative goodness of pretty much any coated waterproof coated or membraned fabric like tarps, tents, raincoats, backpacks, softshells. Its also important to synthetic hiking clothes. Hiking pants, wind shirts etc. 2. Polymers appearing in the worlds water supply. Some of the can surely be attributed to deteriorating plastics in the form of trash, but I did read an environmentalist article where widespread use of synthetic fabrics was to blame. The article claimed that garments made from things like polyester were washed in the washing machine and that over the course of the garments life that it would shed up to 60% of its bulk. As much as I would enjoy telling you all that these environmentalists are full of crap I know that mechanically what they are saying about the polymer fiber fragments going into the water has to be mechanically true. How people choose to deal with synthetic fibers remains to be addressed. I could see a appliance specific septic filter cartridge working, but as mentioned it remains to be addressed, so how people choose to deal with it is in the air. In any event disruptions in synthetic fabrics would really shake the dynamic. So, these are some of the things I have had some thoughts about how about ya'll,.....any thoughts?
