Rugged Flex®

Rugged Flex

Carhartt Rugged Flex® technology moves and stretches with you throughout the day so that whatever you're doing, it's easier to do.

Rugged Flex® garments must meet the Carhartt's defined standards for stretch, recovery, and durability, so when you put on a Rugged Flex® garment, you know it won't let you down. You'll find Rugged Flex® in shorts, shirts, pants, jackets, and boots because you need gear that helps you move, not gear that holds you back.

How to Measure

Note: For best results measure over your undergarments. Use a cloth measuring tape.

measure men's baselayer


Measure just under your arms and across your shoulder blades, holding the tape firm and level. If your chest falls between sizes, order the next size up.


Measure the fullest point between your natural waist and crotch.

Natural Waist:

Bend side to side and find the natural bend in your body; this is your natural waist. Note: It may not be the smallest point.


Measure from your crotch to the desired length on body. You may also measure pants that you currently own and like. Lay the garment flat and smooth out. Measure on the front from the crotch point along the seam to the hem for the inseam length..
