About our brand

"With Fortress, you can wear less layers of clothing, and have less weight with a more dynamic temperature range. You can go from it being 50 degrees and jump into frozen Arctic water and have it be 20 degrees or 30 degrees outside and still feel comfortable.

Testimonial

"The Fortress base layer was a game-changer. It allowed us to film on days that we normally wouldn't have been able to and we could stay out in the cold longer than the camera equipment could handle. That's when I was really sold on it. The battery life in our camera gear couldn’t keep up with Fortress. This is next-level stuff."

No Cold Chills!

"With other clothing, if you exert yourself at all and start sweating, you get cold. Fortress is incredibly unique. When you get wet, you stay warm.”
-- Outdoor Enthusiast

Testimonials

"I get tired of putting layers on and taking them off again. Fortress is
insulating and breathable at the same time, so it keeps you comfortable at a
wider range of temperatures -- even if you're exerting yourself and sweating
in the cold."

All of the planning, preparation and time it takes to play outdoors is totally worth
it – except when someone gets cold and you have to call it a day. Staying
warm, even when you’re soaking wet, allows you to continue to hunt, fish, camp and ride without having to sacrifice safety.

"You can think better when you're warm and not shivering and shaking. I've been
out in midwinter -- particularly in directing traffic. You focus a lot on
being cold instead of doing your job. Anytime you're distracted, you're more
prone to making mistakes or overlooking something that's important. I hated
being cold."

★★★★★

"Fortress Clothing allows me to exert myself in the wilderness and sweat in the winter
time months, and not be concerned that I'm going to die of hypothermia,
versus cotton or any other type of material out there. Fortress Clothing
allows you to mitigate your body moisture, because even when it's wet, it
still heats me up, and I haven't found anything else that can even come
close."

Very good, but can be improved

They're very warm and they're awesome to have in my emergency bug out bag.
I would have put the rubber sole up higher around the side of the whole hot sock instead of just higher on the back heel of the hot sock. That way they would be more durable to walk around in. But I will only use these in an emergency, not to walk around with. And because I have a hard time reaching down and pulling them on I am using suspender clips to clamp onto both sides of the opening of the hot socks to easily pull them on. But I might sew some 7 or 8 inch nylon webbing straps to both sides of the opening of the hot socks so I can grab the webbing and easily pull the hot socks on and then tuck the nylon webbing into the hot socks.
