Men + Women’s Pant Sizing

MEN: Use the measurement of your jeans for a correct fit. Find your waist measurement first then look down the column for your inseam. It is better to go more snug than not, so if you are on the edge of a size do not be concerned or size up unless your inseam allows. 

WOMEN: Measure around natural waist—not too loose, not too snug then from the inside top of thigh to the middle of ankle bone. See diagram for where to measure.

Airtex Shirt Sizing

SIZING QUESTIONS? Confused about your size? In between sizes or need assistance? Call 704-663-0351 or email [email protected]. We’ll get back to you quickly. Please include your height, weight, and chest measurements.

MEN:

Your chest measurement is important to get the right fit. Our shirts are meant to be snug, not tight and certainly not loose. We want the armor close so it protects you when you need it. Your chest measurement from high school might not be your size now so please double-check. If you only have a ruler and don’t have a fabric measuring tape, use a piece of string to measure and then measure the string.

If your belly is larger than your chest, no worries, just let us know. We can fit 99.9% of men (and have for almost 26 years), sometimes we just need a little more information about your shape when you no longer look like Brad Pitt. So let us know in the notes at checkout what your measurements are if you are on the fence about your size. We’re happy to help. 

Regular Sizes – Under 6’2 – Measure under your arms around the fullest part of the chest, level across the back. Order based on chest size.
Regular Sizes – 6’2 and taller – Measure under your arms around the fullest part of the chest, level across the back. Order based on chest size but let us know your height in the notes at checkout
