The new Harrier continues where the original left off. A finely crafted all day, every day training top made with the finest merino wool to keep you cool when it's hot out, warm when it’s cool.

The difference comes with the material. Wool is one of nature’s most magical materials. The new Harrier is 89 percent merino wool, 11 percent nylon, and considerably lighter than the original. It’s versatile when the mercury rises. Naturally odor resistant. Speed ready.


When it comes to performance fabrics, merino wool is a freak of nature. If you’ve never worn it before, you’re in for a revelation. A natural, surprisingly soft fiber that stays warm even when drenched with sweat, it also resists odor without washing for longer than you can bear to imagine. And we tested it the hard way, running morning and evening through the dog days of the Boston summer. One run? No problem. A week of runs? Still funk-free. One month without a wash? Put it this way: we lost our nerve long before this natural fabric showed any sign of losing its battle against bacteria.


Formal cross country traces its history to the 19th century and an English game called Hares & Hounds. It's how runners earned the nickname, “Harriers.”

We were inspired by these hardy racers to craft our Harrier collection, training tops designed to withstand whatever coach or Mother Nature throw your way.
