⭐⭐⭐⭐⭐ Excellent Shelter

"I used this tent on a 420 mile trek this summer. The set up and breakdown was fast and easy with a little practice. The vestibule doors options provided great rain protection and cross ventilation and can be closed up tight in a strong wind. The inside is spacious so I could spread my gear out with plenty of headroom to sit up in my chair. The dual doors and screening made entry and exit a bug free breeze and the bath tub floor was easy to keep clean of debris. I will be putting plenty of miles on with this tent!" - Michael

Two Person Backpacking Tent

Spacious. Secure. Ultralight. The Lunar Duo – Explorer redefines what a single wall, ultralight tent can be.

With an unsurpassed space-to-weight ratio, it’s no wonder the Lunar Duo - Explorer is affectionately referred to as The Backcountry Palace. The pitch design provides a lot of interior space, and that doesn’t even include the two vestibules. It’s the perfect tent for anyone looking for livability without greatly compromising weight.

*To completely repel water, shelters need to have sealer applied to the seams before use.
*Shelters including a seam sealing service may not ship immediately.


Three Words Describe the Lunar Duo:




This tent is at home in a campground as much as a top a windswept ridge and large enough for four adults to sit and play a game of cards. No matter how bad the weather, you can batten down the hatches for a comfortable nights sleep. Lunar Duo offers no compromises despite the fact that it’s less than half the weight of your traditional tent.


The Lunar Duo offers the most interior room of any tent in its class and weight range. Dual curved poles located on either side create a unique arched roof. Combined with a tent height of 45 inches and width of 54 inches leaves so much interior space you've got room to spare.

With dual oversize vestibules, each person has plenty of weatherproof storage for gear. The Lunar Duo's two vestibules can be deployed to multiple positions. When fully open, it provides maximum cross ventilation, keeping you cool and those pesky mosquitoes at bay. They can be raised or lowered, ensuring that you can achieve the optimum configuration for the weather you're likely to encounter. The Lunar Duo's vertical sidewalls prevent rain falling into the tent.

Like all our shelters it is designed to be pitched with adjustable trekking poles or with our fixed length aluminum or carbon fiber poles (sold separately).


Dual Vestibules provides excellent gear protection.

High Vents minimize condensation formation.

Dual Entry ensures you have an available door.

Easy Tension Adjustment makes re-tension your tent easy.

Floating Canopy allows the canopy to be set to different heights.

Dual Hiking Pole Support

Dual Cargo Pockets.

Extremely Easy Setup in less than five minutes under any conditions.

Always performs great

Its been with us from Patagonia, Iceland, Hoh Rain Forest, Sequoia etc. including a once in a decade deluge coming down from Mount Whitney.. with rain so hard it clogged the road drains at Whitney Portal and we never had a drop on us.. super light, nice size for my wife and I and never had any condensation including a trip to the Canadian Rockies. Only wish is it came in DCF

Light, big and cool.

Used this shelter on an overnight through arid badland backcountry at Grasslands National Park East Block in southern Saskatchewan. I set up this shelter to wait out the hottest part of the day in around 10 minutes with little practice. Ventilation is excellent and the shelter performs well as a sun shade in arid summer conditions when you need to conserve water. The shelter is easy to see from kms away for away-hikes in open terrain and performs well in moderately high winds with good anchors.

The Lunar Duo - Explorer tent is pretty awesome

I took this tent on a hiking trip with my son on the 4-Pass Loop trail in the Maroon Bells Wilderness Area in Colorado recently. The first night it rained pretty heavy together with some pretty good gusts of wind. This tent (although not setup entirely great by this first-timer) handled the conditions with ease, and we and our gear stayed dry all night. I was surprised by how much headroom and legroom (can stow extra gear and keep it dry) there was in the tent. My son & I are each about 5' 10". The tent is also pretty light and fits in the side ouch of the Gossamer Gear Mariposa 60 pack, which is pretty awesome.

It took us about 5 minutes to pitch once we got the hang of it. Although I'm sure it wasn't necessary, we used a an extra footprint just to keep the tent as pristine as possible.

I would recommend this tent to anyone that requires a lightweight 2-person tent, but still wants some of the extra features (dual doors, extra space / room, etc.)....Love it -- will use again.

Lunar duo review

I have the lunar tent and was looking for a lighter 2 person. Have been very happy with the lunar so I decided on the duo. Works just as well as the single person. The only complaint that I would make is that The Tyvek footprint is too short. Several inches on either end of the tent base lay on the ground. In my experience the footprint should at least be the size of the base. Going to have to find some house wrap and make my own. The $35 for the footprint isn’t worth it save your $. But that would not stop me from recommending this tent. Which I have already told a few friends.
