The Shirt

ActiCool is a proprietary fabric designed to battle heat conditions for any occasion: work, leisure, or sports. Super comfortable and soft to the touch, ActiCool keeps you cool as you heat up.

Using a blend of proprietary hydrophilic fibers in our multilayered yarn, moisture is wicked away from the skin and dispersed throughout the yarn before evaporating. This creates a cooling effect, reducing humidity next to the body, keeping you dry.

See how well ActiCool performs!

Tested in tough conditions
ActiCool was originally designed to keep law enforcement and military personnel cool under their body armour. More recently, our shirts have been used in industrial settings as a means to keep working personnel cool and comfortable. Over and over again ActiCool has proven to be effective in tough conditions. We’re excited to see which tough terrains you’ll take our shirts to next!
Stands the test of high heat & humidity
We’ve put our shirts through the ringer by getting athletes to stress test ActiCool fabric in hot and humid conditions (90F and 50% humidity). All testers happily reported that ActiCool allowed them to push harder and kept them from overheating. Additionally, ActiCool has been successfully tested in everyday activities such as: landscaping, mowing the lawn, and general work outdoors.
Tested with Flir® Thermal Imaging
We've used Flir thermal imaging systems to compare the same athletes wearing cotton & ActiCool technology apparel under identical conditions.

What people are saying

At 102 degrees I took the shirt for an 8 mile off-road cycling test. Even before starting, sweat was running down my arms being outside, however the body under the shirt felt pretty cool. 4 Miles in and I still felt relatively cool compared to a regular dry fit type of shirt in which I felt I would overheat. A breeze created an extra very nice cool feeling to the body.

After about 8 mile bike ride, it feels like I’m not wearing anything at all, really light, breathing really well, big fan!

Brandon Bravo, Former Division III Wrestler, Dallas, Texas

Both my wife and I lead very active lifestyles. Living with the heat of Miami, Florida makes it extra challenging to be active outdoors. We tested the ActiCool shirt for several full days both on the beach and in the water in Miami and Caribbean islands. Playing beach volleyball in the midday sun, I felt a pleasant cooling sensation in the shirt in the heat. In the water, diving and swimming, I was surprised with comfort and a pleasant lightness of the shirt, especially compared to a regular cotton tshirt. Having worn the shirt all day, and leaving it to dry for the next day, my wife was surprised that the ActiCool shirt felt washed and could be worn again!

It seems cool. It’s not as warm as it would be. Doesn’t have that wet feel that wicking does.

Jay Helmer, Construction Super, Ottawa, Canada

The ActiCool shirts are really great because it cools down your temperature as you work out. I was amazed at how quickly I noticed the difference. I would highly recommend the ActiCool shirts for anyone wanting to work out!

Holly Jana, Athlete & McGill University Physical Education and Health Student, Montréal, Canada

That point where you start getting hot and tired you don’t really hit it wearing this shirt, and because of that the exercise seems easier. Before beginning training, I made a point of first doing some cardio exercise. Namely, I jumped some rope. I was really impressed with ActiCool here. The point where I usually start to get hot and begin to sweat never came. My arms began to tire before I could even begin to feel general fatigue! It was very impressive!

Andrei Matveev, Brazilian Jiu Jitsu Practitioner, Montréal, Canada

I LOVE the shirt! Not just the fabric but the colour!! I've been wearing it a lot in my workouts!

Mat Chambers, Personal Trainer, Montréal, Canada

On a recent hiking trip in the Swiss Alps, I tested the performance of the ActiCool shirt in the 86°F temperatures to see if it works. I was pretty amazed to see results fast. It kept me dry on the hike, wicking the sweat quickly. Also left me feeling refreshed. I was able to keep hiking for longer, and stay aware of my surroundings on sharp cliffs and sudden turns. What made it comfortable is its softness and lightness. Sporting the high vis style, I felt safer to be spotted by other hikers as well.

Val Petrov, Competitive Cyclist, New York, New York

I was able to last longer at a steady pace. It felt easier, the shirt didn’t stick to me as much as a regular cotton t-shirt (during the workout).

Ben Mumme, McGill University PHE Student, Head Coordinator of KIN Games 2016, Athlete, Coach, Educator & Lifelong Learner, Montréal, Canada

I felt a lot less hot, generally cooler throughout the workout. It made it easier to get through my reps.

Our story

ActiCool was born out of a desire to bring freedom beyond what limits us. One day, I got a call from a client looking to solve the problem of overheating under body armor. ActiCool was the answer, designed to keep soldiers and law enforcement from overheating, letting them stay dry and comfortable.

As we started our internal testing, we realized ActiCool was so much more!

What many don’t know, is that growing up, I suffered from Raynaud’s disease, a circulation disorder that leads to the body cooling down and then being forced to thermal charge to heat the body back up. This makes you the sweaty kid and makes life uncomfortable.

With ActiCool, for the first time in a long time I realized I had never felt so comfortable. Growing up in the textile industry I’ve tried a lot of materials that wick, dry, cool, and compress. Some had chemicals, treatments and even batteries, but in the end, none really did the job. There was always a side effect; sometimes itchiness, electric currents, and all too often smell. We wanted to make sure ActiCool had none of these.

Now that ActiCool has improved my life, I know there are others out there who would benefit from having access to it! Sharing this product with friends and clients, we gained lifetime supporters among: runners, cyclist, carpenters, mechanics, painters and first responders, to name a few. All are looking for something comfortable and reliable, something that would really works to cool you down as you heat up.
