I tend to wear a mix of things. First lite bino harness, their leafy top and head covering, one of their base layer hoodie type shirts. 5.11 tactical or Duluth pants, darn tough socks (lifetime warranty), random brands for shirts. I do use a lot of USMC issue stuff for cold weather, like rothco fleeces and such. I feel that allegiance to one brand (unless you hunt one area for one type of animal only) is short changing yourself on versatility. For some great cold weather gear, look at Wild Things Llc. They issue a lot of stuff for the US military. I typically turn my nose up to "military grade" marketing ploy garbage, but their stuff is actually really nice, and extremely durable. I have used their Happy Suit jacket for over 10 years now, hunting, camping, skiing, the whole nine yards. It still looks brand new. If you get a lot of snow, they also sell overwhites, which should be pretty handy.
Wild Things has earned a reputation for tough, lightweight technical outerwear, alpine-style backpacks, durable haul–bags, and innovative tactical and military clothing. Our products are currently in the field with every branch of the U.S. Armed Forces and often tailored for mission-specific goals.

My thoughts on First Lite: it's decent stuff, and a moderate value for the money. But I don't feel like their gear is going to last me 5+ years of hunting 30-50 days out of the year. I also dislike their camo pattern. It looks cool, but their arid pattern (cipher I think) is very dark and has a lot of black in it. I haven't tried it yet, but in my state of Oklahoma, I feel like the darkness of the pattern won't "fade in" from a distance, but rather, turn me into a dark blob from 100-300 yards away. Honestly, a lot of coyote brown finds it's way into my hunting clothes, and it works really well for me, especially on the western side of the state.
