Men's Base Layers

Base layers wick moisture away from your skin and regulate body temperature. They transfer sweat outward to keep you dry while trapping heat close to your body, preventing the clammy cold that happens when perspiration sits against your skin during activity.

Merino base layers outperform synthetics in temperature regulation and odour control but sacrifice dry time and durability.

Advantages:

Superior temperature regulation across varying conditions
Natural odour resistance for multi-day wear
Retains warmth when damp
Comfortable against skin without irritation
Disadvantages:

Slower drying time than synthetic fabrics
Lower abrasion resistance
Requires careful washing and handling

Match base layer weight and fabric to activity output and duration:

Hiking/Mountaineering: Midweight merino base layers balance warmth and moisture-wicking for varied effort over extended periods.

Skiing/Snowboarding: Midweight thermal base layers provide insulation on lifts while managing sweat during descents.

Trail Running: Lightweight synthetic base layers maximise moisture transfer and dry time during sustained high output.

Winter Camping: Heavyweight merino base layers deliver maximum warmth when stationary with odor control for limited washing.

Alpine Climbing: Merino blend base layers maintain warmth when wet plus extended wear performance.
