The numbers
The Kalyx Cover is designed to reduce and disrupt a thermal signature; it cannot guarantee you will not be detected. How thermal cameras work · Read the disclaimers
Not your average cover
Thermal imaging systems detect the heat your body emits rather than visible light. That means even in complete darkness, warm objects stand out clearly against cooler surroundings.
Drones, search systems, and surveillance equipment increasingly rely on infrared sensors to detect heat signatures in outdoor environments. Unless something disrupts that signal, your body heat is easy to identify.
Three layers, one system
VAYDR combines three specialized layers into one lightweight system designed to reduce and disrupt your thermal signature.
Dimensional Air-Gap Layer
Copper-Nickel Barrier
Protective Anti-Snag Netting
Together, the three layers work as a system to manage heat transfer, reduce thermal contrast, and provide visual concealment without the bulk of traditional insulated materials. The metallic center also reduces RF signal to electronics underneath it.

Why Vaydr
Thermal Signature
Problem: Thermal cameras detect the heat your body emits, identifying warm objects even in total darkness.
Solution: Disrupt how body heat appears under infrared imaging, reducing the visibility of your thermal signature.
Visual Disruption
Problem: Movement and shape can still be spotted easily in open environments, especially when your outline contrasts.
Solution: Break up your visual silhouette, blend in with surrounding environments, reduce how easily you stand out.
Lightweight
Problem: Most concealment or emergency gear is bulky and difficult to carry in real outdoor situations.
Solution: Designed to fold compactly and deploy quickly, making it practical to carry in backpacks, vehicles, or emergency kits.
Common questions
Sizing and Coverage
The Vaydr Kalyx Cover provides full-body coverage for concealment, ground cover, or gear protection in the field. The rectangular design allows the cover to be easily deployed over a person, equipment, or a small area of terrain while still remaining compact enough to pack away quickly. Reinforced edge webbing and integrated metal eyelets allow the blanket to be secured to the ground, tied to nearby structures, or configured as a temporary shelter or visual barrier when needed.

Features and Materials
The cover uses a three-layer construction designed for durability and thermal disruption. A top layer of cut air-gap webbing helps break up smooth surfaces and diffuse heat, while a conductive metal fabric core helps scatter and redistribute infrared energy.
The cover is reinforced with an anti-snag structural mesh backing that adds strength and prevents tearing during movement through brush or rough terrain. The exterior fabric is made from PU-coated polyester that is waterproof, UV treated, rot and mold resistant, and designed to minimize shine and glare.
Finished with Vaydr’s proprietary Prairiebrush camouflage pattern, the cover blends naturally into dry grass and mixed terrain while remaining lightweight and packable for field use.
Effectiveness & Limitations
Vaydr Kalyx Covers are designed to interfere with thermal tracking systems but cannot guarantee complete protection. Effectiveness varies depending on environment, lighting, camera sophistication, and viewing angle. Best used alongside other disruption practices.
