Engineered for running

Our award-winning Aéras™ fabric is made in France using specially treated nylon and elastane fibers –– super-smooth on the skin, light compression, breathable, sweat-wicking, sleek on the body, and responsibly-made.

Aéras™ (Greek for “air”) embodies our design philosophy of purity in performance and is designed for your daily run all the way up to race day.

Super-smooth second-skin feel

The ultra-smooth surface created using new knitting technology offers a second-skin feel that prevents chafing over long distances. Every detail considered so you can stay in the flow, distraction-free, and focus on your run.

Every detail considered

Sweat-wicking & fast-drying
Built with moisture management fibers, Aéras™ actively pulls sweat away from the skin to keep you comfortable and dry on your daily runs all the way through to race day.

Stretch & SPF protection
The 4-way performance stretch provides gentle compression that supports without restriction, moving comfortably with your body. Integrated SPF protection shields you from the elements.

Responsibly made in France

We sought out the finest performance materials in world and found them in France. The fabrics are made with a focus on the highest level of quality while also adhering to French and EU climate objectives and laws.

Aéras™ is matte (not shiny), contains no polyester, and is not coated in any chemical finishings. It is pure performance fabric.

Philos Origin Story Image

Philos comes from the word “philosophy” whose origins derive from two ancient Greek root words: philo (love) and sophia (wisdom).

INSPIRATION

The origins of running. In Athens, there is an ancient stadium that has hosted running events since 600 BC. It is made entirely from marble from the same quarry as the Parthenon. In 1896 AD it hosted the first modern Olympics and the first ever marathon. It is the oldest monument to the sport of running in existence.

Running on that track was where our founder — marathoner, New Yorker, trained tailor, and former Ralph Lauren designer — was struck by the ancient power of running, the purity of it, the connection across time, and how deeply human it is... the embodiment of the Greek ideal of beauty in motion.

VISION

Running as ceremony. Philos embodies connection: across time, to the planet, to other people, and to yourself. Our vision is empower women in their running journey through sleek and elegant head-to-toe performance solutions.

Philos sportswear is made from the finest fabrics in France, consciously crafted in Portugal, and precision-tailored for running. Our team launched Philos at the end of 2024 in Amsterdam. We expanded in 2026 to New York.
