With a Spring 2020 collection focused on performance pieces inspired by the journey from early season training to a goal race, apparel brand and specialty retailer Tracksmith is also touting a sustainability story that will resonate with eco-conscious runners.

Tested by a cohort of Tracksmith amateur runners in Flagstaff, AZ, and New York City, the full line includes all the essentials a runner needs to weather the season, from temperature-regulating Merino tees and tanks to new compressive training shorts and post-workout sweats.

Tracksmith’s first retail store, The Tracksmith Trackhouse, is located at 285 Newbury Street in Boston. Along with its online collection, the brand also sells in select specialty running stores in the U.S., including Pacers, The Loop Austin, Runologie Raleigh, Fleet Feet Chicago, Ad Astra Big and Peach Running … with more to come in 2020.

The Tracksmith sustainability angle comes into play through the use of Merino wool in many pieces along with the utilization of recycled poly and nylon in many others.

For Tracksmith, Merino in its Harrier collection provides a natural, surprisingly soft fiber that stays warm even when drenched with sweat, while also resisting odor without washing. Tracksmith uses Merino wool in products across the training spectrum — from seamless base layers worn under a singlet to breathable mid-layers for long runs.

Then on a slightly different sustainability note, Tracksmith is increasingly using recycled poly and recycled nylon in a variety of ways, often combining them with natural cotton. Its New England Overshirt is a running overshirt made from a recycled wool, cotton and nylon blend. On the performance side, the NE Half-Zip uses an Italian blend of recycled nylon and elastane. Then there is the NDO Jacket, which incorporates recycled nylon in the lining.

Among the other entries into the Spring 2020 line:

  • The Van Cortlandt four-inch Short ($62) is new for men and will be available for women soon: A four-inch mesh training short with contrast trim, inspired by the pair Oxford Rhode Scholar George Dole wore to line up against Roger Bannister at Iffley Road.

  • The Van Cortlandt Long Sleeve (women and men, $75) is a classically inspired long-sleeve that does double duty as a training layer in early spring or a warm-up on race day.

  • The Session Shorts for women ($68) maintain the fast-feeling of the original brief for while stripping down the design elements to make the silhouette as light and minimal as possible.
