well, just the other weekend I was as happy as pig in shi# with the issue gore-tex gear. It had been raining and snowing in Pet for a few days when we arrived to do some Crater Groups and Bridge Demolition (capitalized because of the big donkey wood factor); it continued raining trough the night and snowing the next day when the C4 and Triag. said goodby. The mud was just below the rimm of the WWBoot and the outer shell on both the jacket and the overpants were completely soaked yet I was perfectly dry and warm even after working all night in those conditions - beats the crap out of the old combat jacket and rain gear combination we had in the late 80s - I looked like a freaking fool with the wide grin I had o my face.
about the Sierra stuff, I haven't seen it.
chimo,
Frank
