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.

My new Union Suit
It's a great piece of clothing. I put it on the first thing in the morning and it's great for getting ready for the day. Dependant on what the weather of the day is, depends on what I put on over it. Once I'm in for the night, they are very comfortable to just hang out in till bedtime.

Stop reinventing the wheel! Not as good as the old one.
I don't like the back flap being horizontal. I work in the sewer business all year round So in the Winter time when I'm in the hole I don't like haveing people kicking snow on my backside. I understand that the old version with the vertical flap in the back probably was an inconvenience but at least now with the flap being horizontal it's like wearing a T-shirt and you have to tuck it in all the time and comes loose all the time if you have to bend over. it just sucks. And I have the original camo one and I love it. This new version not so much. And it feels really light weight and the original was pretty heavy duty. This one is only good if you're gonna be recreational ice fishing or laying around, or whatever but for work no. Unless you're a supervisor or whatever or in your truck all the time not doing any and want something to keep you warmer. And giving it a two stars is me being generous. Because I like a majority of Carhartt products.

Balanced Garment
I appreciated that Carharrt listed the size of the garment the model was wearing in the photos - normally I would size larger, but the photo was a medium on a 6'2" model, which fits my build. Glad I got mediums and not a larger size.

I wear this garment on its own around the house in the winter, and as a baselayer when I take my dog out. I wish the ankles were cut a little bit tighter, but thats really all preference.
