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.

Storm Defender®

Storm Defender®, waterproof breathable technology, stops rain, but let’s sweat escape through a breathable membrane—so you can work through a storm.

Staying dry, focused, and safer is easier with rainwear featuring Storm Defender® waterproof breathable technology. It's made to keep you completely protected from rain and amazingly comfortable inside. Work doesn't stop when it rains; it just gets harder. Lugging rain soaked garments around adds to the misery, but Carhartt's jobsite worthy raingear cuts the discomfort.

PPE for feet
The boots are my third pair. These are truly waterproof and they are rugged. The shoe laces are the weakest part of the boot. On both of my first two pair I've had to replace the laces 6 to 9 months after first use.

Great left boot, right boot hurts the top of my foot.
The left boot works well. Currently I am stuck with a new left boot and an old right boot as a result of the functionality of the right boot. I kneel a lot at work. So the bend in the boot at the ball of the foot is important. For some reason, this right boot keeps pushing on the bones in the top of my foot making it very uncomfortable. I had emailed Carhartt about this and am awaiting a response. That was about a week ago. Waiting to see what we can do about this right boot to make it functional or return.

Nice work boots
These are nice work boots. comfortable, stout and very waterproof! They are a bit bulky, but i do have big feet. I would have liked a thicker shoe lace and a couple more lace holes for the laces.
