Which material is best?

Wool: highly moisture-wicking and odor-resistant
Synthetic: durable and less expensive
Silk: soft and lightweight for casual activities

Match the temp to the trek

Lightweight layers: best for moderate to cool temperatures
Midweight layers: best for cold temperatures
Heavyweight layers: best for below-freezing temperatures

Find your fit

Must be close to skin to efficiently wick sweat; should fit comfortably snug
Base layer is for moisture control; your mid layer is for warmth
