Harrier Sweater | Dark Gray Heather

A performance top for cooler conditions, made from a temperature-regulating merino blend.

Tracksmith was the first running brand to use merino as a performance fabric, a monumental move that created the ultimate natural fiber running top.

One of Tracksmith's original products, refined over the years, perfecting the design using the soft, durable material to create a layer that moves with you, matching the rigors of your runs year after year. A wardrobe constant, the Harrier has stood the test of time for one reason: what works, simply works.
