What size should I choose?
Choosing the right size cycling undershirt comes down to the fit you prefer and how you ride. Most performance cycling undershirts are designed to fit close to the body. This means they should feel snug when standing, but comfortable and natural once you’re in the riding position.
Designed to be a true-to-size fit based on Australian sizing standards, offering a comfortable, performance-oriented feel without being an overly tight European style fit.
If you prefer a tight, race-style fit, choose your usual size for a streamlined, aerodynamic feel. If you prefer a slightly more relaxed fit for casual riding or extra comfort, you may prefer to size up.
As a guide, the undershirt should sit close to the body without restricting movement, with the sleeves and waist staying in place while you ride. A well-fitted cycling undershirt will feel supportive and comfortable—like a second skin—once you’re on the bike.
To find your Brooklyn Project size, refer to our size chart at the bottom of the page and match your chest, waist, and hip measurements. If your measurements fall across multiple sizes, we recommend choosing the size that best matches your chest measurement, as this is the most important factor for achieving the correct on-bike fit.
