Although I have never wore them myself but my brother swears by Under Armour for the starting layer. I personally love the brown Polypropylene pants and shirt underwear. Stay away from the old thermal long under wear aka long johns. They will freeze you to death. Keep your neck area sealed up and covered. I used to wear the biggo thick heavy gloves until I finally figured out that the lighter non insulated gloves worked best for me. Once the big thick gloves are cold they're cold until you get back inside somewhere with heat. The thins ones can be warmed back up just by putting your hands in your pockets with them on. The hand warmers are a nice asset too. 100% wool socks with a wicking liner if you can't stand the wool directly against your skin. 100% wool sweaters like the Army Surplus always sold is extremely warm. Some brand of quality insulated bibs and coat. With the bibs and coat you get double coverage over most of your upper body.
