Women’s base layers: merino wool vs. synthetic

Choosing the right base layers depends on your activity level and the environment you’ll be exploring. Merino wool is a favourite for its soft feel, breathability, and natural odor resistance. It’s an excellent choice for activities where sweat isn’t the main focus, like relaxed hikes, camping or downhill skiing. With its ability to regulate body temperature and resist odors, merino wool is a reliable, high-quality option. Synthetic women's base layers, often made from performance polyester or polypropylene, are stars in durability and moisture-wicking properties. These layers are lightweight, quick-drying and more affordable, making them ideal for high-energy activities like trail running, mountain biking and cross-country skiing. Synthetic options keep sweat at bay, ensuring you're comfortable even during the most intense adventures. For the best of both worlds, hybrid merino-synthetic base layers combine the temperature regulation of wool with the resilience and performance of synthetics. These versatile options are perfect for women tackling a variety of activities year-round.

Perfecting your layering system

Your base layer is the starting point, but it’s most effective as part of a complete layering system. Once you’ve selected your base layer, add a mid-layer for warmth and an outer layer for protection. Mid-layers, such as fleece or insulated jackets, help trap heat while pushing moisture outward. Outer layers, typically waterproof or windproof, act as shields against rain, snow, and cold winds. For dynamic weather or extended adventures, mastering the art of layering is essential. A carefully chosen base layer enhances comfort and performance by regulating temperature and managing moisture. Need help?
