Base layers for women: Choose your perfect fit
Finding the right base layer makes all the difference in your comfort and performance.

Merino wool base layers provide enhanced comfort
Merino wool delivers exceptional performance in all weather conditions. Its naturally soft fibers feel smooth against your skin and effectively prevent odors during long activities.

When temperatures drop, thermal base layers create a protective barrier that keeps you warm without overheating.

Advanced features in women's base layers
Modern base layers combine smart design with performance materials to support your active lifestyle. Each piece features carefully chosen materials and ergonomic cuts that work with your body's movement during any activity.
Temperature regulation technology
Advanced materials create a responsive layer that adapts to your changing activity levels. The specialized fabric structure retains heat when you're cooling down and releases it when you're working hard, helping to maintain a comfortable body temperature throughout your workout.

Rather than constantly adding or removing mid-layers, you can rely on your first layer to handle minor changes in weather and effort, giving you more freedom to focus on your performance.
Moisture management systems
Effective moisture control is essential for comfort during activities. The fabric actively pulls sweat away from your skin to prevent that cold, clammy feeling during intense moments. Here’s what you’ll find in the collection:

From material selection to manufacturing processes, each decision focuses on reducing environmental impact while maintaining high-performance standards. The materials meet strict sustainability certifications, ensuring responsible production methods that deliver lasting quality.
