How to Buy Thermal Underwear

What you put against your skin has a lot to do with your comfort and safety in the wilderness. Buy wisely.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Thermal Underwear
• Waterproof Hats
• Waterproof Hiking Boots
• Waterproof Jackets
• Waterproof Pants
• Waterproof Gloves
• Waterproof jackets

1. Determine what thickness or "weight" to buy, depending on conditions and activity: the colder the temperature and the less activity you'll be engaged in, the thicker the underwear.

2. Look for "wicking" underwear - material that spreads out moisture and dries quickly.

3. Ask about odor retention. Older materials such as polypropylene tend to get stinky; several newer materials hardly retain any odor.

4. Find materials that are easy to care for - that is, those that are machine-washable and, preferably, machine-dryable.

Tips & Warnings

• Spend generously. You'll thank yourself the night after that cold front that wasn't in the forecast sweeps through. Plus, a quality piece of thermal underwear will last for years.
• Avoid cotton at all costs. It's a terrible insulator when wet.

on 11/22/2005 I bought some thermals which are 50% Viscose and 50% Polyester. I highly recommend the material ratio, they are light weight and absorbent, but very warm (and yes, go for a tight fit). I found the review in WHICH magazine. And I found a site on the net that sells them very cheap. Definitely worth it.
