Make Your Tent a Haven,
Not an Oven.

Addressing Summer's Heat: The Missing Piece in Overlanding Gear

Overlanding takes you to the most remote corners of the earth, from the sun-drenched trails of Moab to the rugged expanses of the Australian Outback. While winter journeys have the cozy warmth of heaters and fuel stoves, summer brings a relentless heat that can turn your adventure vehicle or tent into an oven.

At ZERO BREEZE, we enhance outdoor comfort with groundbreaking gear designed to overcome these challenges. Our latest innovation, the world’s first air conditioner built for the outdoors, operates off-grid.
It efficiently uses limited energy resources to cool your RTT, tent, or vehicle interior quickly, ensuring you rest well and wake up invigorated for another day of adventure.

Summer Sleep: Your Real Overlanding Challenge

Nightfall in the wilderness brings its own set of challenges, especially when temperatures that felt comfortable by day transform your tent into a stifling trap by night. Overcoming the heat during sleep is crucial for your next day's adventures.

Why It Matters:
Even slight overheating can disrupt your sleep, degrade its quality, and reduce your recovery rate, impacting both your physical and mental performance the following day.
Proper sleep setup can prevent the fatigue and cognitive deficits that come with sleep disturbances, ensuring you are ready for whatever the trail throws at you.

Mark 2 AC:
The Best Off-Grid Air Conditioner for Overlanding

Overlanding is more than just a way to travel; it's a pursuit of freedom and adventure. This group of passionate explorers often drives their four-wheel vehicles deep into forests, climbs to the tops of mountains, and ventures into challenging, less-traveled places.
In these remote areas, being self-sufficient is not just a choice but a necessity.

However, in such environments, conventional comforts are often hard to achieve, especially during the hot summer months. How can one ensure effective cooling while maintaining portability and saving space? This is where the Mark 2 AC proves its worth:

Precision Energy Efficiency

Designed for low power consumption, the Mark 2 AC operates on just 240W and delivers 2300 BTU of cooling power, optimized specifically for Overlanding needs. Its efficient energy use ensures continuous cooling even in environments with limited power supply.

Learn why 2300 BTU is the smartest choice for Overlanders

Power Up Anywhere, Anytime

Recharge your Mark 2's battery effortlessly via your car's cigarette lighter, solar panels, or existing power systems. No complex setups needed—just plug and play to keep the cool going.

Designed for the Outdoors

Effortless Portability

Mark 2 AC revolutionizes outdoor air conditioning with its manageable 16.5 lbs design, making it as easy to carry as your camping essentials. Compact yet effective.

Ready, Set, Cool!

Just place the Mark 2 AC next to your RTT or tent, route the ducts inside, and turn it on. Enjoy immediate cooling without any installations, electrical modifications, or power setups.

Experience Real Comfort:
Mark 2 in Action

Watch how the Mark 2 AC transforms a heated insulated tent into a cool haven during the peak of summer.

Baum's test of the ZERO BREEZE Mark 2 portable air conditioner in an insulated tent dramatically lowered temperatures from a high starting point during the day to a much more comfortable level, demonstrating its cooling efficacy in hot conditions.

  • 4:42 PM: Starting temperature was 93.2°F.
  • 6:03 PM: Temperature quickly dropped to 66°F.
  • 7:10 PM: Temperature continued to decrease to 54°F. 
  • 9:44 AM the next day: Temperature stabilized at 60°F.

Usage Recommendations:
While this test was conducted in an insulated tent, the Mark 2 AC is also suitable for various non-insulated tents and rooftop tents, especially effective during nighttime use to provide the necessary cooling.
Although the air conditioner was placed inside the tent for this test, it is recommended to externalize the unit when using RTTs or other outdoor tents to save space and simplify the drainage process.
