Utmost Province® offers custom Formula 1-inspired apparel in unisex sizes for adult from S to 2XL.

For sizes 3XL and 4XL, contact client services via our contact form , and we may be able to accommodate your order depending on our inventory levels.

The fit of Utmost Province® custom F1 shirts depends on the type you order. For our Formula 1-inspired tees we use Comfort Colors garment-dyed shirts and SUPIMA® cotton t-shirts. Our apparel size guidelines page have the size charts which you may use as a reference to determine the right fit for you.

Each shirt runs true to size; therefore, if you prefer an oversized shirt look and feel, we recommend going up a size.

The measurements for Utmost Province® F1 apparel are measure in average inches as well as centimeters. Whether you are looking at a graphic tee, crop top or hoodie size chart, each is measured laying flat.

Measure Sleeves:

For shirts and crop tops you measure from the center of your back (below the collar), over the shoulder, down the end of the sleeve. For hoodies and sweatshirts you start from the same spot, and continue down the outside of the arm to the wrist bone.

Measuring Chest Width:

To measure a shirt's chest width, you start by laying flat then measuring straight across from one armpit seam to the other.

Body Length:

To measure the length you lay the garment flat then measure from the top center collar down to the bottom of the garment.
