I just went through this process and ended up buying pretty much a full set of the Russell Outdoor gear. I bought most of it at camofire, but some of it from linton outdoors.
I have everything in the Russell APXg2 gear in my grubby little hands except a Zephyr L3 Jacket that I just ordered. Initial thoughts are that I'm very impressed with the Cyclone L5 rain gear. The L1 lightweight base layers are really nice too, very smooth and not super tight like the underarmour stuff. The L2 stuff is only going to work for me if it is below freezing and I need to sit for a long time. I about broke a sweat just trying it on at the house. The Gale L4 jacket should work very well in the cold, but I'm afraid I won't use it very often. It will still be nice to have though. I didn't bother with the L4 bibs, I can't think of anytime that I will be out in the cold that long sitting still that I would need them. The Zephyr line is what I'm planning on using pretty exclusively with the lightweight L1 base top. I haven't decided, but I'm debating picking up an extra pair of Zephyr L3 pants and a couple extra L1 base layer tops if they go back on sale again.
Here's my total cost in the Russell gear that I've picked up. This doesn't include shipping on the camofire items, but I used the add on shipping option and they were all sent in 2 shipments. The stuff from Linton Outdoors shipped free with orders over $100.
L1 Alpine Base Pants $20 - Camofire
L1 Alpine Base Top - $25 - Linton Outdoors
L2 Tundra Pullover - $42 - Camofire
L2 Tundra Pants - $40 - Camofire
L3 Zephyr Jacket - $60 - Linton Outdoors
L3 Zephyr Pants - $55 - Camofire
L4 Gale Jacket - $80 - Linton Outdoors
L5 Cyclone Rain Jacket - $75 - Camofire
L5 Cyclone Rain Pants - $68 - Camofire
That totals up to $465, throw in the shipping on the camofire stuff and it gets up around $480 total. That gear would have cost well over $1,000 at full retail.
I also found a 2009 close out pair of Ascent pants at footwear outfitters in Idaho. They ended up run $92 including shipping so a pretty good deal on them.
On inital reaction, I like the Sitka Ascent pants better than the Russell L3 Zephyr pants, but I think the Russell pants are supposed to be a little better at shedding water. I like the optifade camo better than the Mossy Oak Treestand, but I am one of those guys who really doesn't feel like the deer care one way or the other on the color of the camo though.
I'm going from twill pants and cotton T-shirts with some cheap mad dog rain gear to this setup, so hopefully it will work out for me. I wasn't really ever super uncomfortable in the old stuff, but hopefully this will have me set for many years to come.
I'm now addicted to the camofire site and will probably end up with some more stuff before it is all said and done.
