Base Building

We designed this short sleeve base layer specifically for racing in colder conditions where it can be worn as light insulation under a singlet. Turns out, it's not just great on the race course, but it excels on its own on hard training days or under a mid layer when the season grows cold. Its seamless construction gives it a comfortable, flattering fit that’s not too tight to wear by itself. It features an engineered Merino mesh that’s more open around your core, with a closed knit on the shoulders and sleeves for extra warmth.

16.5 Micron Merino Wool Blend
52% Wool, 28% Nylon, 20% Polyester
Constructed Seamlessly To Prevent Chafing

Because the Brighton Base Layer is intended to be worn against your skin, we wanted to eliminate any points of possible irritation or chafing. So we went to Europe and partnered with one of the most innovative seamless factories in the world. The result is a garment built for a level of comfort to rival your favorite pajamas, and a level of performance without any rival at all.


Legendary marathoner “Boston Billy” Rodgers once owned a running store on the Marathon course in Cleveland Circle, right before the turn onto Beacon Street, where rowdy Boston College students crowd against the barriers cheering the marathon runners as they head into the final few miles before the finish line.

Among the unique articles Bill wore during runs from that shop was a simple mesh layer with polypro jersey sleeves. The idea was that your core generates enough warmth but your shoulders and arms need a little extra protection.

Bill’s old fishnet shirt was the inspiration for our base layer.


If you’re still not familiar with the performance benefits of Merino wool, be prepared for a revelation. Stunningly soft and not at all scratchy, Merino wicks moisture and regulates temperature just like animal hair (because it sort of is). It’s almost completely impervious to odor, even if you never choose to wash it. Unlike synthetic wicking materials, Merino stays warm even when it’s wet. And it’s sustainable, too. Our Brighton Base Layers are made from a lightweight, luxurious 16.5 micron Merino blend, and constructed seamlessly to reduce any chance of chafing.


The Brighton Base Layer also comes in a long sleeve.
