Made from moisture-wicking polyester, 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. 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.

Patagonia makes four Capilene fabrics for different levels of exertion and temperatures. 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.

Polygiene® odor control permanently protects your garments from smelling like a locker room. Sweat itself is odorless, but it creates the conditions that bacteria need to multiply, and some of those bacteria produce odors. Polygiene permanent odor control stops the growth of odor-causing bacteria on fabrics, so you can wear more and wash less.

Active only on the fabric surface, Polygiene permanent odor control does not interfere with perspiration or with the skin’s natural bacterial flora. Polygiene particles are more than 100 times larger than nanoparticles and therefore are too large to penetrate to the skin’s barrier. 

Patagonia has worked with bluesign technologies since 2000 to evaluate and reduce resource consumption in its materials supply chain, and to assist with managing the chemicals, dyes and finishes used in the process. bluesign technologies, based in Switzerland, works at each step in the textile supply chain to approve chemicals, processes, materials, and products that are safe for the environment, safe for workers, and safe for the end customers.

In 2007, Patagonia became the first brand to officially join the network of bluesign® system partners.

Any fabric you see that’s bluesign® approved offers the highest level of consumer safety by employing methods and materials in their manufacture that conserve resources and minimize impacts on people and the environment.
