What Are Bunny Boots?
Bunny boots, officially known as Extreme Cold Vapor Barrier Boots (Type II), represent one of the most effective cold weather footwear solutions ever created. These distinctive white rubber boots were designed by the U.S. military to protect soldiers' feet in the harshest arctic conditions, with a temperature rating down to -60°F (-51°C).
The unique design features multiple layers of insulation sandwiched between vacuum-sealed rubber barriers, creating an incredibly effective thermal protection system. Unlike modern synthetic insulations, bunny boots use up to one inch of wool felt insulation, which maintains its insulating properties even when compressed or damp.
What sets bunny boots apart from conventional winter boots is their vapor barrier construction. This system prevents moisture from your feet from penetrating the insulation layer, while simultaneously blocking external moisture. The result is consistently warm, dry feet even in the most extreme conditions.

The term "bunny boots" comes from their resemblance to the white winter coats of snowshoe hares found near Fort Greely, Alaska. Just as these hares change from brown to white for winter camouflage, the white boots help military personnel blend with snowy environments while providing unmatched warmth protection.
Key Features That Make Bunny Boots Special:
- Vapor barrier construction prevents moisture infiltration
- Up to 1 inch of wool felt insulation for maximum warmth
- Waterproof rubber exterior withstands harsh conditions
- Temperature rating down to -60°F (-51°C)
- Military-tested durability and reliability
History and Military Origins
The story of bunny boots begins during the Korean War, when U.S. forces faced devastating frostbite casualties during the brutal winter of 1950-51. The Battle of Chosin Reservoir became a turning point, not just strategically, but in military equipment development. Soldiers equipped with standard leather boots suffered extensive cold injuries, highlighting the urgent need for superior cold weather footwear.
The U.S. Army's Natick Research and Development Center in Massachusetts took on the challenge of creating footwear that could protect soldiers in the world's coldest operational environments. Their research led to the development of the vapor barrier boot concept, which represented a revolutionary approach to cold weather protection.
Evolution Timeline:
- 1951: Initial development begins following Korean War casualties
- 1962: Type I (Mickey Mouse) boots introduced - black, rated to -20°F
- 1967: Type II (Bunny) boots developed - white, rated to -60°F
- 2024: Alaska Gear Company launches modernized VBX Bunny Boots
The first iteration, known as Mickey Mouse boots due to their oversized appearance, provided protection to -20°F. However, military planners needed equipment capable of operating in even more extreme conditions, including Arctic operations and high-altitude missions where temperatures could plummet to -60°F or lower.
This led to the development of the Type II boots - the true bunny boots. These improved designs featured enhanced insulation, better materials, and the distinctive white color that provided both camouflage and reflected heat back to the wearer. The boots became standard issue for Arctic operations and remain in military service today, over 70 years after their initial development.
What makes this military heritage particularly relevant is the rigorous testing these boots underwent. Unlike commercial winter boots, bunny boots were subjected to extreme testing protocols, including extended exposure to temperatures well below their rated limits, immersion testing, and long-term durability assessments under combat conditions.
The success of bunny boots extended beyond military applications. They became essential equipment for researchers in Antarctica, oil workers in Alaska, and anyone working in extreme cold environments. Their proven track record in the world's harshest conditions has made them legendary among cold weather professionals.
My Experience with Bunny Boots
"In my 15 years of testing outdoor gear across North America's most challenging environments, bunny boots have saved me from frostbite more times than I can count."
My first encounter with bunny boots came during a winter photography expedition in Yellowstone National Park. The temperature had dropped to -35°F, and my expensive modern winter boots were failing miserably. A veteran park ranger noticed my struggle and offered to lend me his personal pair of surplus bunny boots.
The difference was immediate and dramatic. Within minutes of putting on the bunny boots, my feet began warming up. What impressed me most wasn't just the warmth, but how my feet stayed completely dry despite the challenging conditions. I spent the next eight hours photographing in temperatures that had defeated my previous footwear.
Since that experience, I've tested bunny boots in various extreme conditions across Alaska, Montana, and northern Canada. During a particularly challenging assignment documenting winter wildlife behavior in Denali National Park, temperatures dropped to -47°F with sustained winds of 40+ mph. My bunny boots performed flawlessly during 12-hour days in these brutal conditions.
One lesson I learned from an experienced Alaskan guide was the importance of proper sock selection. He recommended merino wool blend socks with a thin liner, explaining that cotton socks would defeat the vapor barrier system. This advice proved invaluable during extended cold weather expeditions.
The most challenging test came during a winter camping trip in Alaska's Brooks Range. For three days, temperatures never rose above -40°F, and we were camping directly on snow. Each morning, I watched other expedition members struggle with cold feet while my bunny boots kept me comfortable enough to enjoy morning coffee without rushing to warm up.
Personal Pro Tips I've Learned:
- Size down 2-3 sizes from your normal shoe size
- Use thin merino wool liners under thick wool socks
- Allow boots to dry completely between uses
- Keep the air valve closed during ground operations
- Consider snowmobile boots for different conditions
What really convinced me of their superiority was a side-by-side comparison with premium modern winter boots costing three times as much. During identical conditions over a week-long expedition, the bunny boots outperformed every modern alternative in terms of warmth retention, moisture management, and overall comfort during extended wear.
The weight is definitely noticeable - at over 3 pounds per boot, they're not for casual winter walks. However, when the temperature drops below -20°F, that weight becomes insignificant compared to the protection they provide. I now consider them essential equipment for any serious cold weather expedition.
