Capilene® synthetic baselayers wick moisture away from your skin, breathe efficiently and dry fast to provide the foundation for any layering system for any pursuit. Collaborating with our ambassadors and field testers, we continually work to improve our Capilene fabrics and their construction. All Capilene fabrics have achieved bluesign® approval; have an updated and consistent fit in each fabric weight; and use Polygiene® technology to control odor in the garment. They are the best baselayer option for high-sweat activities and wet conditions.

Made from moisture-wicking polyester, Capilene fabrics keep you warm even when wet, dry quickly, and manage your moisture, whether you’re breaking trail on a steep skin path or belaying on an alpine route. Designed for fast-forward, aerobic activities, they’re quick to wick and quick to dry. Capilene polyester is made from recycled polyester (35% recycled content or more) and is also machine washable.

We make four Capilene fabrics for different levels of exertion and temperatures.

Capilene® 1 Silkweight is our stretchiest Capilene performance baselayer fabric for breathability and ultra-fast dry times. Worn alone, it provides 50+ UPF sun protection and a cool, drying airflow. Paired with another layer, it wicks moisture and adds warmth when temperatures drop.

Capilene® 2 Lightweight is our fastest drying Capilene performance baselayer fabric. A great weight for aerobic use in mild to cool conditions, its open-knit construction breathes and wicks moisture. Capilene 2 provides 20-UPF sun protection when worn alone and insulates in cool to cold conditions beneath layers.

Capilene® 3 Midweight is the most versatile of our Capilene performance fabrics. Soft and compressible, Capilene 3 Midweight baselayers stretch, dry quickly, resist wear and provide excellent insulation and next-to-skin comfort. Midweight is a versatile, do it all baselayer for active use in cool to cold conditions.

Capilene® 4 Expedition Weight is the warmest and most breathable of our Capilene performance fabrics. It’s made to keep you dry and comfortable in cool-to-cold conditions. Soft, stretchy and compressible, it has a smooth face that glides beneath layers and a brushed fleece interior to warm your core, wick moisture and feel smooth against your skin.

All of our Capilene performance fabrics incorporate Polygiene® technology to control odor.
