I have the old Mtn Pants, new Ascent pants, 90% jacket and Celcius vest. Also have a few shirts, not sure what they are called.
I love the stuff for any type of hunting, late cold season in N GA, late winter hog hunting in CA, Summer hog/deer hunting in CA, and Late Summer/early Fall deer backpack hunts in CA.
It dries insanely fast, is durable, and just fits. I am 5'8" and 155, I have never had a pair of pants that fit without taking them to the tailor. Hard to complain about a $100 of great pants when I have taken $50 mediocre pants cut to fit a gangsta rapper and had them tailored for $20-$40 a piece. Even then the fabric doesn't "move with you" like the Sitka stuff.
That Celcius Vest may be the pest piece I have, it is far warmer than its weight or even loft would lead you to believe.
I know I sound like a salesman, but I am just a very satisfied customer.
With a pair of gloves, a thin wicking and warmth layer, a beanie and the 90% jacket-ascent pants-shirt and vest and I am good to freezing. Throw on a packable rain jacket and you have windproof and waterproof in a package that compacts very small.
Can't wait to be wearing my Sitka stuff, holding my Black Widow with a 60lb pack on my back hiking into the Eastern Sierra's. A smidge over 2 weeks and I am there!!!!
