I've found that a decent pair of sweat pants/shirt works great for me. Works better than the regular themals I used to wear. Got mine at Wal-Mart for maybe $18.

I don't have to walk around much, so this works great for me. I'll be good w/ sustained temps. around 25-30* F. Ofcourse, that includes another THIN layer, and my insulated bibs/coat. I see no need in spending big $$$ on thermals for the area I hunt.

I usually carry my bibs/coat and just walk to my stand w/the rest (above mentioned) on. Put the rest on when I get there. Oh, my stand is only like 100yds or so from my back door! If I had to walk more, I might invest in some of the other stuff. But, I don't. So, I won't.
