How to Choose the Best Patagonia Capilene Baselayer

Patagonia Capilene fabric is used to make some of the best and well known technical baselayers in the industry. The synthetic polyester weave provides the foundation for any layering system and is adaptable to a myriad of sports. All of Patagonia’s Capilene baselayers are bluesign approved, meaning Patagonia follows a set of guidelines meant to reduce waste and boost sustainability of their products.  Regardless of weight, the Capilene product line also features a contemporary and consistent fit, and makes good use of Patagonia’s Polygiene Odor Treatment technology to fight off odors accumulated after multiple days of skiing or outdoor activity.

Jans has been carrying Patagonia Capilene products since they were brought to the outdoor market. And while other brand’s baselayers are competitive, Capilene baselayers have a special spot in our hearts. Our Experts have been using these technical baselayers for years and for many of us, they are the only ones we will reach for. So what is Patagonia Capilene and what do all the numbers and weights mean?

Capilene 1 Silkweight

Capilene Silkweight products come in a wide variety, which allows you to use them for anything from fly fishing to running or as a first layer for skiing. They are also the stretchiest and thinnest of the Capilene baselayers. When worn under a second layer for skiing or winter aerobic activity, this lightweight baselayer will help keep you warm and wick moisture to keep you comfortable. Be warned though, you’ll most likely want to layer more if you use a Capilene 1 baselayer due to how thin they are. For summer hiking, climbing, or running, Patagonia Silkweight baselayers are breathable and quick drying to help your body better manage its own temperature.

Capilene 2 Lightweight

Lightweight is Patagonia’s fastest drying baselayer. Ideal for aerobic use like running, ski touring, and Nordic skiing, Capilene 2 has an open-knit fabric composition that really lets the air in and moisture out. And a 20 UPF sun protection rating keeps the sun off your back when you’re working your hardest. This men’s Capilene 2 long sleeve is great when worn on its own or under a jacket for some hard spring skiing.

Capilene 3 Midweight

If you’re not sure where your next adventure might take you, reach for the Midweight Capilene baselayer. These are Patagonia’s most versatile baselayers; and are ideal for mild to cold temperatures. They stretch, wick moisture, and are quick drying and highly compressible for easy packing. You could easily take them anywhere. These men’s Capilene 3 bottoms make a great first layer for skiing, hiking, or climbing all winter.

Capilene 4 Expedition Weight

Your coldest days out on the hill call for Patagonia’s Capilene 4 Expedition Weight baselayers. Still soft and stretchy, these baselayers have a brushed fleece interior to warm your core and feel smooth and comfortable against your skin. They also pack up tightly should you need to de-layer when the day warms up significantly more than you expected. This women’s Capilene 4 zip-neck top is perfect for under a ski jacket or on its own if you’re getting after a trail run on a cold winter morning.
