Base Layers

Find your merino wool base layer for any activity

Merino wool base layers provide temperature regulation and odor resistance that synthetic materials cannot match. The merino wool construction naturally regulates temperature and prevents odors, making these pieces ideal for athletes who need reliable performance gear. The close-fitting design allows a full range of motion during activities like trail running or winter hiking.

Merino wool differs from regular wool due to its finer fibers, which feel soft against the skin without the itchiness associated with traditional wool garments. The tops use premium merino wool, which provides natural temperature regulation, keeping you comfortable whether temperatures rise during intense effort or drop during rest periods. This natural fiber adapts to your body's needs without requiring synthetic treatments or chemical finishes.

Lightweight merino wool base layers solve the challenge of staying comfortable during variable-intensity activities. The lightweight merino wool construction maintains breathability while providing insulation, and the shirts use soft, itch-free merino fabric combined with moisture-wicking properties that help you stay comfortable during long training sessions. Some shirts include thumbholes to keep the sleeves positioned correctly during dynamic movements.

The base layer pants feature an elastic brushed waistband for a secure, comfortable fit during extended wear. The products have flat seams that prevent irritation during movement, ensuring comfort even during multi-hour endurance activities. The close-fitting design works effectively under additional layers, creating an efficient layering system for changing weather conditions.

Why choose a merino wool base layer for optimal temperature?

Merino wool's unique fiber structure creates a natural temperature regulation system that synthetic materials cannot replicate. Unlike synthetic base layers that either trap heat or leave you cold, merino wool fibers actively respond to your body temperature changes, expanding when you're warm to release heat and contracting when you're cool to retain warmth. A quality men's baselayer made from this material adapts to your body's changing needs, whether you're pushing hard during intense effort or cooling down during rest periods.

Stay dry and fresh with a merino wool base layer

Merino wool fibers have a natural crimp structure that creates tiny air pockets, while the fiber's ability to absorb up to 30% of its weight in moisture without feeling wet allows sweat to move through the fabric efficiently. These wool base layers actively transport moisture away from your skin to the fabric's surface where it evaporates quickly. The flat seams across the garments prevent chafing during extended wear, while features like thumbholes on some shirts keep sleeves positioned correctly during dynamic movements.

Natural odor resistance with merino wool base layers

Merino wool contains natural antimicrobial properties that inhibit bacterial growth, which is the primary cause of odor in synthetic fabrics. The lanolin present in the wool fibers creates an environment where odor-causing bacteria cannot thrive, even during extended wear periods. This natural resistance means the garments maintain freshness during multi-day adventures or consecutive training sessions when washing isn't practical.

Experience superior comfort with your merino base layer

The shirts use soft, itch-free merino fabric that eliminates the scratchy feeling often associated with traditional wool garments. This natural comfort comes from merino wool's fine fiber structure, which feels smooth against your skin even during extended wear. Flat seams across all the garments prevent chafing and irritation during movement, ensuring you stay comfortable during long hikes or intense training sessions.

Move freely in your wool base layer

The close-fitting design works with your body's natural movement patterns while providing the layering benefits you need for temperature management. Raglan sleeves on some tops allow enhanced freedom of movement through the shoulders and arms, particularly beneficial during activities that require full range of motion. The pants feature an elastic brushed waistband that moves with you while maintaining a secure, comfortable fit under other layers. Some shirts include thumbholes that keep sleeves positioned correctly during dynamic movements, preventing them from riding up during stretching or active motion. This makes these pieces ideal additions to your men's clothing collection or essential components for cold-weather activities in the winter collection for men.

Choose the right merino wool base layer for your adventures

The weight of merino wool directly affects its insulation properties and breathability, making thickness selection crucial for different activities and temperatures. Lightweight options excel during high-intensity activities where moisture management and breathability take priority over maximum warmth. These thinner constructions allow better air circulation while still providing merino wool's natural odor resistance. Heavier weight base layers trap more air within their fiber structure, creating additional insulation for colder conditions or lower-intensity activities. The flat seam construction across all weights prevents irritation, while the close-fitting design ensures optimal thermal efficiency. This variety makes them valuable additions to collections like cozy layers for different seasonal needs.

How does a merino wool base layer provide warmth?

Merino wool's fine fiber diameter creates countless tiny air pockets that trap warm air close to your skin, forming an insulating barrier against cold temperatures. The natural crimp in merino fibers enhances this effect by creating more surface area for air retention compared to synthetic materials. These base layers maintain their insulating properties even when damp because merino wool can absorb up to 30% of its weight in moisture while still feeling dry against your skin. The moisture-wicking capability prevents the cooling effect that occurs when sweat accumulates, which is essential for maintaining core body temperature during extended cold-weather activities. This natural temperature control makes them particularly suitable for pieces in the winter collection for women.
