Provides Warmth: Designed to provide warmth to the wearer's core, using Patented AERIS^™ 250 Insulation Technology (4” / 6mm of loft) which is crucial for staying warm in colder weather conditions even when wet. The insulation and material used in vests helps trap body heat, keeping the wearer warm and comfortable.
Increased Mobility: Excellent level of warmth while allowing for more freedom of movement than a bulky jacket. This makes them perfect for outdoor activities like hiking, hunting, or fishing, where you need to have your arms free to move around.
Versatility: Insulated vest can be worn alone as a top layer or layered underneath a jacket for added warmth. This makes them versatile enough to wear in different weather conditions, making them an ideal piece of clothing for any season.
Lightweight: Extremely lightweight, making it easy to carry around and pack in a bag. This is especially useful for people who are constantly on the go or need to travel light.
Fashionable: It can be paired with jeans or other clothing items to create a stylish outfit.
Affordable: Compared to our full-fledged jacket, insulated vests are often more affordable. This makes them an excellent option for those who want to stay warm while being budget-friendly.

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."

"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."

Yes

It's super light. Comfy, would recommend. It is pricy than most vests I would pay but I can tell the quality will last. Great customer service. Pretty easy to return if sizing is off.

This vest is Ultra light

Im happy with the vest; it's the most stylish Fortress piece i have. i work in a temp controlled room and this gives me the extra warmth i need under my jacket without having another set of sleeves restriction my movement. I used it outside a couple of times and it does provide alot of warmth for something sleeveless.

Almost great

Very warm. Runs on the small size for a medium. Collar is rather tight. With a few improvements it could be great. Did I mention it is very warm.

Love the product

I love how warm you are using a product it’s very light so it’s packable

Great all day vest

Probably the best vest I've owned comfortable on the body thin light and warm good for being in a vehicle all day and working outside

Only drawback would be that the collar is too tall because the vest fits tight it rubs under the chin when zipped up and makes hoods awkward to wear over without folding it down and the material isn't really made to do that properly. Hopefully if there's another version in the future this will be addressed

first impression is that it is great

Unfortunately , it is 90 degrees in my home town so impossible to say how warm it will be once winter gets here

The Best

Fortress was the best company I have worked with on line. Both Dale and Mike answered my questions immediately and pleasantly.
My new jacket is the best — just had a chance to enjoy its warmth and comfort at the Jersey shore.

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

Soft!

These Fortress base layers are amazingly soft and comfortable! They are far superior in comfort in our opinion to the military ecwcs layering system. Plus with Fortress you have less layers vs ecwcs. Also with Fortress you can get soaked wet and still get warm. However with ecwcs primaloft soaked wet...uh oh your in trouble. (same with goose down) We have not tested these yet in the cold, but we remember when we first tried on the ecwcs system before we tested it in the cold. (and the ecwcs works well in the cold) The fortress feels way better in temperature regulation thus far pre cold test vs the ecwcs pre cold test. I have every confidence Fortress will blow away ecwcs in the cold with less layers and more comfort. That’s why we bought the whole family not only one set each of these base pros, but 2 sets! Did I say they are comfortable oh my!
