This thing is awesome. I am always a little skeptical when it comes to things that claim to be anti-stink or self cleaning but this shirts truly is. I decided I would put it to the test so I literally did this entire past week of marathon training with the shirt without washing it once… I know what you are thinking… Gross right? Well the shirt didn't mind at all. It kept me at the perfect temp... Read more

This was my first purchase from Tracksmith. The long sleeve Brighton Base Layer is a wonderful garment. It’s warm enough to wear solo on 40-degree days and would serve as a great base layer for anything in the 30s or lower. I’m 5’9” / 150 pounds, and I ordered the Small. It’s very snug, but base layers are supposed to fit tightly. You won’t be disappointed with this item.

This is probably the best Tracksmith top that I’ve purchased to date. It’s lightweight but warm & doesn’t require frequent laundering. I took one on a trip over the holidays, wore it on every run, and it fresh when I returned home. Highly recommended!

Incredible base layer that can be used for a surprisingly large range of temps on its own, or layered with other gear. Really love the color, too.

The color is beautiful and the material is very comfortable. I wonder what it would be like if it could be thicker.

Great material and the sleeves are long enough for my monkey arms! I usually wear a medium, so I had to exchange the medium for the long but am very happy with the fit and performance on a sub-freezing trail run.

Fantastic garment. It’s soft, seamless and almost bafflingly doesn’t smell after runs (at least nowhere near normal shirts). I typically wash every time and I’ve worn this 4x so far. It’s keeps me warm under a fleece but breathable so it’s not uncomfortable. Amazing piece of kit.

Clutch Layer

Our best-selling Brighton Base Layer features an engineered Merino mesh, a stunningly soft, moisture-wicking blend that regulates temperature and is virtually impervious to odor. We designed the top as a training base layer to be worn under a mid-layer or jacket, but its seamless construction gives it a flattering fit that’s not too tight to wear all by itself. It’s built for a level of comfort to rival your favorite pajamas, and a level of performance without any rival at all.

  • Constructed seamlessly to prevent chafing
  • Designed with a closed knit on the sleeves for warmth at the extremities
  • Can be worn on its own or as a base layer
  • Made in a sustainable Merino mesh blend
  • 52% Merino Wool, 28% Nylon, 20% Polyester, 16.5 Micron, 145 gsm
  • Odor Protection
  • Moisture-Wicking
  • Temperature Regulation
  • Machine wash cold. Hang dry.
  • With a standard fit that runs true to size, the performance top touts comfort and stretch to support your efforts in cold weather.

Key Features

Miracle of Merino

Made from a Merino wool blend, the super soft and not at all scratchy top wicks moisture away and regulates temperature. If you’ve never experienced the performance benefits of the miraculous material, be prepared for a revelation.

Seamless Innovation

Because the base layer is intended to be worn against your skin, we wanted to eliminate any possibility of irritation or chafing. We partnered with one of the most innovative factories to create a seamless garment with the utmost comfort.

Engineered with Intention

The Merino mesh is more open around your core, with a closed knit on the sleeves to keep your arms warm. Perforation around the chest, back, and underarms allows for air flow without impeding on the fabric’s ability to maintain an ideal temperature.
