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.

$170 for less than two months of use
VERY disappointed with these boots. Recieved a pair of these for Christmas 2020, and in less than two months on the job, and the toes of the soles are separating from the body of the boot. Damn shame, because I actually liked them. Wore them a few times a week through January to break them in. Started wearing them daily in the beginning of February, and found them to be comfortable. However, about 2wks ago, I noticed the toe on the right boot beginning to separate. Today, noticed the left was also starting to separate. For the cost of these boots, they damn sure should have lasted longer than a month and a half. Pretty ticked off to be honest

I love the grip and the insulation. These boots come feeling tough and they show it too. I put my boots through tough conditions and these have held up so far. They are also comfortable which is hard to find in a work boot. Very impressed.
