Front is some sort of wind blocking material while back is more breathable. waterproof, super comfortable, and a slimmer cut, though not as tight as the tech pants because the material is a bit looser.
Only negative is that there are no side pockets, only the tiny zipper key pocket on the back.
also picked up the non-fleece tech pants that are more like chinos. too chilly to wear yet but were comfortable when I tried them on. didn't realize they have elastic parts on both sides.
That's how it always is with JJ. It was working fine for the few seconds before J23 and them blasted. It was the preferred spot when the backdoor links were still working. No more though.
Nikestore.com will be the easiest way, no doubt about it. I'm thinking about picking up a 2nd pair even though that one will probably never see the light of day due to the limited days I can even wear sneakers.
