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.
-- Outdoor Media Company Owner

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."
-- Peter Smith

★★★★★

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."
-- Police Officer James

★★★★★

"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."

Snug as a bug. Hot like a furnace.

I grew up in a tropical country, shorts and tank top weather all year round. Moving to Melbourne was a shock to the system. Winter was a rude shock. No matter what I wore, layers upon layers of heat tech, sweaters just never cut it. Chanced upon fortress from some random Shark tank video on YouTube and gave it a chance. Bought the 1/4 Base and the pants. Nothing else has kept me warmer, I dread the days I have to take them off to wash. Has kept me toasty. Love my fortresses

Simply Wow!

I met Dale and Devan at the Shot Show. Wow! These guys were very helpful and informative about the Fortress Gear. Enough so, I bought almost every item they were selling. It's the warmest and most comfortable clothing I have ever worn outside and it keeps you surprisingly comfortable inside. You won't be disappointed!

BasePro was the bomb!

I recently used the BasePro 1/4 Zip, top and bottom, on summit night and for sleeping at night on Kilimanjaro. For the weight it was the smartest article of clothing I brought. Simply put, you get what you pay for! I can't wait to use it on other hikes, hunting, snowmobiling, skiing and especially ice fishing. Heck, I may even wear it around the house in the winter, it's like thermal pajamas on steroids. :)

Does the Job Very Well

This is the perfect base layer. It's thin where it needs to be so when working hard your body can breathe and get moisture out, but then has the insulation in the right spot so when you're in the cold and not moving a lot it keeps you very warm.
