100% Waterproof - Fully Encapsulated Insulation System
Engineered for extreme cold weather protection, the Bunny Boot delivers unparalleled warmth, dryness, durability, and comfort. It is built using 100% waterproof vulcanized rubber and utilizes the same techniques deployed by the US military to combat frostbite while utilizing modern technology and materials to create superior fit, function, and performance.
Built for the harshest winter environments, the VBX Bunny Boot delivers dependable warmth and comfort in severe subzero conditions, outperforming traditional cold-weather footwear.
The VBX (Vapor Barrier X) system is a waterproof layer that surrounds multi-layer wool insulation, keeping it dry. By blocking outside water and inside perspiration, it preserves warmth and performance in extreme cold, ensuring comfort even in overflow or extended use.
Layered insulation traps body heat while blocking the transfer of cold, creating a powerful thermal barrier for extended wear in extreme climates.
Fully seals the insulation from both sides, preventing water from flooding in or sweat from soaking through—eliminating the #1 cause of winter boot failure.
An aggressive diamond-lug tread delivers superior grip on snow, ice, and mud, with reinforced high-wear zones for lasting durability in rugged terrain.
With a comfort rating of -34°F, a capability threshold of -57°F, and a maximum survival limit of -79°F, it delivers strong performance in very cold weather.
The Original Airboss Bunny Boot has a CLO value of 1.61 and is rated for use in temperatures ranging from -20°F down to -65°F. The AKGC VBX improves slightly on this with a CLO value of 1.79, giving it a comfort range of -25°F to -70°F. For maximum insulation, the AKGC VBX Max is the warmest model, with a CLO value of 2.14 and a rating of -34°F to -79°F. The AKGC VBX Composite follows closely, offering a CLO value of 2.01 and a comfort range of -30°F to -75°F. Finally, the AKGC VBX LITE is designed as a lighter, more mobile option, with a CLO value of 1.36 and a range of -5°F to -50°F.
Bunny Boots was never an official name, but instead a nickname for the boots officially known as Extreme Cold Vapor Barrier Boots (Type II). These were developed by the U.S. military during the Korean War to protect troops in arctic and subarctic conditions. The Bunny Boot nickname was derived after the snowshoe hare. As their fur turns from brown to white in the winter, more hares appear with their new "white boots".
Mickey Mouse Boots (Type I): Black, rated to -20°F. Ideal for cold but less extreme conditions. First iteration of Bunny Boots.
Bunny Boots (Type II): White, rated to -60°F. Designed for the harshest cold, including Arctic and high-altitude operations. Developed after original Bunny Boot and more commonly used current day.
VBX Bunny Boot (From Alaska Gear Company): White, tested compatible performance to Type II. Designed with innovative VBX technology, tested in Alaska, and equipped to support comfort in the harshest cold weather conditions.
The innovative Vapor Barrier X (VBX) technology prevents condensation from penetrating and freezing in the inner insulation layer, ensuring consistent warmth. The multilayer insulation system effectively blocks heat transfer, keeping the cold out while retaining warmth inside the boot. The boots feature vented hydrophobic insoles that keep feet dry and supported, as well as reinforcement of high-impact areas of the outsoles for enhanced comfort during prolonged wear.

Our VBX Bunny Boots feature a modern, valve-free design, eliminating the common failure point found in traditional military-issued versions. This engineering upgrade enhances durability, retains warmth more effectively, and ensures long-lasting dryness and comfort in extreme conditions.
VBX Bunny Boots are heavily insulated, extreme cold-weather boots built to withstand the harshest winter conditions. Perfect for snowmachining, ice fishing, mountaineering base camps, and countless other cold-weather adventures, these rugged rubber boots are designed for all-day warmth and reliability. Their wide opening and slip-on design make them easy to take on and off, combining convenience with serious performance.
For best results, clean your VBX Bunny Boots using a soft brush and warm water with mild soap. Avoid harsh chemicals or cleaners, as they can damage the rubber exterior. After use, remove the insoles and allow both the boots and insoles to dry completely before storing. Always store in a cool, dry place to maintain performance and extend the life of your boots.
We recommend synthetic or wool blend socks that wick moisture. Avoid cotton. For very cold conditions, a thin liner sock plus a thicker insulating sock works well. Always ensure there’s enough room to maintain circulation.
Yes. While VBX Bunny Boots come with a built-in liner system, they can accommodate aftermarket insoles or orthotics for added arch support or custom fit, just be sure not to compress insulation too much.
Yes, your feet may sweat, they’re designed as vapor barrier boots to trap warmth and block moisture from outside. It's important to:
No, VBX Boots do not use Thinsulate. VBX boots keep you warm with a proven multilayer insulation system - built to perform where other materials can’t. Unlike synthetic fibers such as Thinsulate, which lose their effectiveness when exposed to the heat of vulcanization, our insulation stays durable, reliable, and ready for the cold.
Yes. We offer domestic shipping throughout the U.S. and international shipping to most countries. Shipping options and costs will be displayed at checkout.

The boots feature vented hydrophobic insoles that keep feet dry and supported, as well as reinforcement of high-impact areas of the outsoles for enhanced comfort during prolonged wear. The boots come with True Fit insoles available in standard and downsized options, accommodating different foot sizes and shapes for optimal fit. The high traction outsole, equipped with deep diamond-shaped lugs, offers superior grip and stability in icy, snowy, or muddy conditions.
Notably, the Bunny Boot omits the air valve found in military-issued versions, eliminating a common failure point and preventing water infiltration into the insulation layer. This comprehensive design ensures that the Bunny Boot provides reliable protection and comfort in the harshest cold weather conditions.
Waterproof: Fully constructed with vulcanized rubber, these boots are 100% waterproof and have greater abrasion resistance and elasticity in cold temperatures.
VBX Technology: Vapor Barrier X technology ensures that the condensation formed by the warm air in the boots' interior does not penetrate and freeze in the inner insulation layer, compromising the system.
Multilayer Insulation System: The multilayer insulation system prevents heat transfer by shielding against frigid exterior temperatures while retaining heat inside the boot.
Ergonomic Performance: The boots feature vented hydrophobic ergonomic insoles designed to keep your feet dry and supported for superior comfort and performance.
True Fit Insoles: These insoles come in two sizes: standard and downsized. The standard insole is sized according to the Brannock scale, and the downsized insole allows you to decrease the boot size by half size and may be better suited to narrower feet.
High Traction Outsole: The outsole features deep-widespread diamond-shaped lugs for increased traction and stability on ice, snow, and mud while preventing mud and snow from accumulating underfoot. The outsole is reinforced in high-impact zones to improve longevity and foot support.

These boots are very robust and ruggedly built for winter work. I’m psyched to use these on my snowmobile this winter!
Bunny Boots
This is one high quality boot. Looking forward to winter this year!
Amazing product!!!
The boot is built incredibly sturdy, but it feels like walking on a cloud. The upper portion is flexible which makes it nice for walking and moving about.
