Women's Base Layers

While the terms are often used interchangeably, there are subtle differences. Base layers like our Stealth Seamless collection are designed as the foundation of your layering system, focusing on moisture management and comfort next to your skin. Thermal clothing is broader and includes any garment designed for warmth. Our women's base layers serve as thermal clothing but offer much more - they're engineered with advanced Merino X Polyamide blends for superior thermal regulation, breathability, and comfort. The seamless construction eliminates chafing, making them incredibly comfortable for extended wear, which is just as important as their thermal properties.

Generally, no - base layers are designed to be worn directly against your skin for optimal performance. Our Stealth Seamless base layers work best when they can effectively wick moisture away from your body. The fine merino wool structure is specifically designed for comfort next to skin, and wearing anything underneath would compromise the moisture-wicking capabilities and thermal regulation. The seamless construction ensures there are no pressure points or chafing, so you'll find them incredibly comfortable worn as intended - as your first layer.

Absolutely! Our women's base layers are fully capable of functioning as a single layer in milder climates. The Stealth Seamless collection is designed to be versatile - whether you're wearing them as a first layer in sub-zero environments or on their own during moderate weather activities like trail running or hiking. The compression technology provides muscle support, while the breathable merino wool keeps you comfortable. Many women find them perfect for active pursuits where you want the performance benefits without additional bulk.

Base layers should fit snugly but not restrictively tight. Our Stealth Seamless base layers feature compression technology that provides muscle support and enhanced circulation, so they're designed to fit close to your body. This snug fit is essential for effective moisture wicking and thermal regulation - loose base layers create air gaps that reduce performance. However, comfort is equally important, which is why our seamless construction eliminates pressure points. You should feel supported and comfortable, with full range of movement, but without any loose fabric that could bunch up under additional layers.
