I know a thing or two about the AW Tech pants. The first two pairs that I got were from the prototype batches. If I remember right, Sean Gere and I got a pair each to field test, Paul got one and one never got worn. Similar setup for the second batch of prototypes. The originals are a bit rough after being worn for this long so I bought two new pairs at the ISA show.
The material is a Cordura fabric. If you don't know what Cordura is, Google will fill you in. Short answer, a REALLY tough fiber!
For me, the ultimate test of the Tech Pants came a couple of summers ago when I was doing a scientific research project with a researcher from the US Forest Service. Jenny Juzwick has been researching oak wilt for a long time. That summer I was hired to innoculate some red oaks with oak wilt in order to have a controlled study of the effects of a "claimed" cure. The first day of climbing was hot and humid by Minneapolis standards. Ninety plus degrees and ninety plus humidity with no air movement. While I was driving home, with the AC cranked up, I realized that I was feeling rather crummy. Even though I had eaten well and drank lots of fluids.
The next day I did the same climbing and the weather conditions were the same. Ate the same breakfast and lunch with lots of water. By now you're wondering what any of this has to do with AW Tech Pants. On the first day I had TPs, the second, plain old, broken in blue jeans. When I was driving home the second day I felt rotten. Not crummy, really crappy. As I analyzed the day to try to figure out what was different the only variable was my pants. The TPs were in the was because of the walk through poison ivy. My conclusion is that the TP fabric allowed my body to cool just a bit better during the day. Since cotton isn't as effective as synthetics in moving water it didn't radiate my bodies heat like the Tech Pants.
I get such a boot out of the talk about cost of pants and such. No one ever has said that doing performance mods on chainsaws wasn't a great value. When anyone starts to wonder if any of the second-string chainsaws are worth considering, even for an occaisonal user, they get shot down. For a long time I've considered my clothing as valuable to my health and production as any of, what are normally thought of as tools.
Besides, I was wearing my new, black AW Tech Pants and my sweetie said that I looked sharp in them. She's never commented on how I look in work jeans. I can't put a value on that comment
