A seamless, lightweight long sleeve made from an engineered Merino mesh 

Our best-selling Brighton Base Layer features an engineered Merino mesh that’s more open around your core, with a closed knit on the sleeves for a bit more warmth in your extremities. We designed it specifically as a training base layer to be worn under a mid-layer or a jacket, but its seamless construction gives it a comfortable, flattering fit that’s not too tight to wear all by itself.

"Soft, breathable, and odor-resistant, the Brighton Base Layer is ideal for cold runs when you need to layer, and can also be worn on its own."
—Runner's World

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 base layers are made from a lightweight, luxurious 16.5 micron Merino blend, and constructed seamlessly to reduce 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.
