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.

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.

Stylish & durable. I usually wear these during the early fall months and early spring. They have plenty of flex in them and are very comfortable.

Good but wish it were better.
I like the fit and style. Good height on the waist but, the leg length seemed a bit longer than I would expect from a 32"L; have to cuff them with boots. Decently tough material. Biggest complaint is the color; after the first wash on cold setting, these pants look noticeably worn. Would've expected better dye retention. I want to really appreciate these pants more but I think the quality is a bit lacking. Too bad.
