Men's Rash Vest Sizing Model

*Our Men's t-shirt sizes tend to run small since they are tailored for a fitted cut. Generally speaking, this means that compared to regular cut t-shirts, our tees are a bit longer and slimmer. If you are used to regular cut tees, we recommend you select one size over.

Please review our sizing chart and fit guide carefully to determine the t-shirt size that is appropriate for you. If your t-shirt size is not available, we may accommodate a request for a different size currently not available on our site. Please write to us and include the name of the design, the size you seek and the t-shirt color - contact us here


Our rash vests come in a unisex fit but they run one size small. This means that if you are a t-shirt size Medium, you should order a size Large or even XXL depending on how loose you like your rash vests. As a rule of thumb, one size up will give you the proper fit for a rash vest.

Fit Guide *Use measuring tape

SHOULDER WIDTH (1): Measure from one shoulder end to the other shoulder end.

CHEST (NOT SHOWN): Measure under arms around the fullest part of the chest. Be sure to keep measuring tape level across back and comfortably loose.

CHEST WIDTH (2): Measure under arms from one to the other. Be sure to keep measuring tape level across chest and comfortably loose.

WAIST WIDTH (3): Measure around natural waist.

LENGTH (4): Measure from neck to waist.

Tips

Loose Fit: Tee shoulder width and chest width should be 1 to 2 inches longer than your measurements.

Slim Fit: Tee shoulder width should be the same as your shoulder width.

50/50 Tees offer more stretchability to fit the contour of your body so they work well if you prefer the SLIM FIT.

If you don't have a measuring tape, use a piece of string to mark your measurements. Then use a ruler to measure the piece of string.

Women's Rash Vest Sizing Model

*Our Women's Slim Fit T-Shirts run small since they are tailored for a fitted cut. Generally speaking, this means that compared to regular fit t-shirts, slim fit tees are usually one to two sizes under and are a bit longer and tighter. If you are looking for a Women's regular fit t-shirt and none is available, you can choose from our Mens selection which also deliver a Unisex regular fit. We suggest you review our sizing chart carefully to determine what t-shirt size works best for you.

You can check out the "T-shirt Styles" section to see how you can DIY (Do-It-Yourself) customize the fit and cut of your t-shirt.


Our women's rash vests come in a unisex fit but they are true to your women's t-shirt size. This means that if you are a t-shirt size Medium you should order a size Medium rash vest or even a size Large depending on how loose you like your rash vest.
