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 women's pants

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 the fullest point between your natural waist and crotch.


Measure from your crotch down 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.

Gotta ding Carhartt for trying to save money on two belt loops!
Great cargo pants. Wish that they had two more belt loops like they used to have! As a professional gardener, I must carry a bunch of tools, and it is difficult to keep my pants up with out the extra support from the missing belt loops. Otherwise, very sturdy pants that I would recommend.

Good all-rounder slim fit pant
Excellent fit and nice combination of weight and mobility with this material blend. I found them to be a bit longer than normal for the 34 inseam than other models of their double-knee pants but not a big deal. I will likely order a few more colors now that I know I like the pants and the size.
