Your Sleeping Bag Keeps You Warm. The GameChanger Does More.
Most sleeping bags are designed to trap heat. Unfortunately, they can also trap moisture from sweat, breath, and condensation. When that moisture builds up, comfort suffers, and insulation can lose its effectiveness.
The GameChanger changes that.
Powered by K3Core's proprietary Keloflex technology, the GameChanger is a lightweight, self-drying sleep system engineered to manage moisture and maintain a stable sleeping temperature, even as conditions change.
Use it on its own, or slip it inside your existing sleeping bag to dramatically upgrade your sleep system without replacing the gear you already own.
What Makes It a GameChanger?
Self-Drying Technology: Keloflex moves moisture away from your body and out of your sleep system, helping you and your gear dry while you sleep.
Temperature-Stable Comfort: Designed to keep you comfortable from 75°F to 30°F by itself, and adding it to your current system can push that down to 0°F and below.
Upgrade Any Sleeping Bag: Add Keloflex moisture management and temperature stability to the sleeping bag you already own, extending its versatility across different conditions.
Stay Warm, Even When Conditions Turn Wet: Unlike conventional insulation that can lose effectiveness when saturated, Keloflex is designed to manage moisture using only your body heat.
Lightweight & Packable: Weighs under 4 lbs and compresses to approximately 10 liters with a compression sack.
Head-to-Toe Comfort: Tuck your head inside for added warmth while Keloflex helps move moisture from your breath out of the system.
Built to Last: No zippers, no waterproof coatings, and no fragile insulation. Machine washable and designed to withstand repeated compression.
One System. Endless Possibilities.
From backpacking and camping to emergency preparedness, travel, or simply getting a better night's sleep at home, the GameChanger is designed to go wherever you do.
And when conditions take an unexpected turn, moisture management becomes more than a comfort feature. It becomes an important part of keeping your insulation performing when you need it most.
Successfully funded at over 4× its Kickstarter goal, the GameChanger is now available beyond Kickstarter.
