Layering to stay warm

The best advice I've seen on the subject to date:

Via Rogue Angels :

- merino wool socks, heavyweight: whatever you do, leave all cotton at home.
- mid-weight or heavyweight long underwear bottoms, preferably wool or polypropylene
- fleece pants to wear over your long underwear
- a tank top that is not cotton-a mid or heavyweight base layer, ideally polypropylene, but light polar-tec works
- a wool sweater or heavy fleece
- a soft shell jacket, windstopper (not necessary but sweet if you have one)
- rain jacket-gloves, 2 pair: ideally one pair fingerless wool or fleece and one pair with fingers wool or fleece
- a neck gaitor is nice on really cold days-a warm wool or fleece hat
- a baseball hat-(i have tons)
- sunglasses, preferably polarized WITH croakies
