    • Camouflage tent only does not have reflective cording or webbing.
  • Velcro tabs for ridge pole and trekking/tent poles.
  • Utilizes a pair of trekking/tent poles, 130 cm +, for setup (not included).
  • Requires 8 stakes, minimum.
  • The lateral ridge pole connecting the inverted trekking/tent poles allows the entire headroom height to be usable space and makes the tent very stable under wind loads. 
  • Requires seam sealing prior to use.
  • Stakes and awning pole sold separately.
  • Optional tent poles sold separately.
  • Optional orange zipper pulls sold separately.


  • Stake out the 4 corners of the tent keeping the floor slightly taut.  Make sure the sides are squared off and parallel.
  • Unzip the mesh door and sit inside on the floor of the tent with the ‘ceiling’ of the tent on top of your head.  
  • Extend both trekking poles to between 120 cm and 125 cm and slide them into the tent next of you.
  • Insert the tip of one trekking pole into the opening of the ridge pole.
  • Tuck the handle of the trekking pole into the side of the tent wall, on the floor.  Then raise the ridge pole to the ceiling, raising the tent as it goes.  There is Velcro to secure the ridge pole in place.
  • Slip the tip of the second trekking pole into the other end of the ridge pole, and slide the handle into its spot on the side wall, along the floor. At this point, the tent should be loosely erected.  Take care that the trekking poles do not slip out of the ridge pole as they can cause damage to the tent.  There is Velcro to secure the trekking poles in place along the sidewall at the top of the bathtub wall.
  • If you cannot extend the trekking poles enough to remove the slack in the side walls, step outside the tent, loosen the tension on the 4 corner Line Locks, then try to raise the trekking poles a little higher and get a tighter pitch to the tent. 
  • After the trekking poles and ridge pole are secured in place, step out the tent and adjust the Line Locks at the 4 corners so that the corners are standing upright and there is no slack in the walls of the tent. Stake out the mid point tie outs along the head and foot ends of the tent. 
  • Now stake out the fly using the tie out cords provided.  The fly will not come all the way down to the ground.  It should be a few inches off the ground to allow airflow under the fly.
  • Ridge vents have a short plastic ‘stick’ at the bottom.  Velcro this to the vent cover to open ridge vents.  Vents can be closed by lowering the stick.
  • Cooling temperatures and humidity changes will cause silnylon to sag.  This is normal, you can extend the hiking poles a little to tighten the tent and/or re-stake the tent. 
  • For the AWNING, place the tip of the awning pole in the grommet at the tip of the awning, and adjust the placement/angle of the pole so the awning is taut.  Stake out the awning with the tie out cord located at the tip bringing the cord nearly straight down to the ground.
  • To lower the awning for ‘storm mode’  loosen the tie out cord and remove the awning pole (do not remove the stake to the tie out cord for the awning).  Attach a small carabineer to the loop of the orange loop at the tip of the awning and the 2 loops that are about 18 inches away on both sides of the tip of the awning.  Now, tighten the tie out cord so that the fly is now folded and the awning looks the same as the regular fly side.  
  • There is a small elastic loop near the top of the awning, and an elastic cord with a toggle on the underside of the awning, you can roll the awning up for full views and ventilation by securing the toggle to the loop on the outside of the tent.

Good for Tall Hikers, BUT...

Have this tent after a couple of years and many trips. The best part about this tent are the floor measurements, which really are friendly to tall people like myself. I also really like the amount of width that allows for two 25-inch wide pads plus a few inches to spare, or room for all your gear if solo. I really like the innovative "porch-mode" on one side that can be cinched down for bad weather. I always mention LightHeart Gear to my taller friends. To me this is a TRUE 2-person tent. HOWEVER: It's not the lightest out there, you pay for the extra floor space in weight. Setup is odd & somewhat inefficient, but doable with practice. The narrow 12-inch ridgeline really does negate the advantages of a 55-width floor width. The tent is really tight on interior room when you sit up on the inside. Also the rear-vestibule is borderline unusable it's so small on interior space to put gear & storm coverage/airflow. While located in the correct place, the ridge vents are a bit sloppy in construction, they don't provide a consistent shape for reliable airflow (I've tried many, many different times to get this right with zero success). Also very disappointing is that the exterior ridgeline seam fabric started to pull away from each other, so I had to reseal/glue them together to prevent it from getting worse. OVERALL, a pretty good first-generation tent, but there is lots of room for improvement. I would recommend (for a 2nd-gen Duo) a much wider-ridgeline, both vestibules have the porch capability, additional guy-out lines for the head & foot end roof fabric (for greater interior space), and tighten-up the ridge vent execution. I would imagine there wouldn't be a lot of weight penalty, but it would be worth it. If LightHeart Gear made this “2nd-gen” tent out of DCF, it would be one of the top shelters on the market.

Our favorite

We've had this tent for about 4 years now. I have to say it's the best tent I've ever had! My husband and I fit perfectly in it. And even sometimes with our grandson, he's six and loves to go backpacking and hiking with us. Our packs fit in it, because we don't leave them outside. I use mine at my feet and Hubby uses his as a pillow. I even bought the Firefly to use as a single tent when I go out with another group but I'm sleeping alone, and I usually just take the Duo so I can stretch out and have room for my gear. My favorite thing about this tent is how fast it is to set up. I haven't had to seam seal it since we got it, but I have put water proofing on it. This is an amazing tent. Thank you Lightheart Gear for making this awesome tent.

Blue Mountain

Camped on Blue mountain in 30 mph wind gusts at 28 degrees. The tent kept us warm and stoop up the the wind with out any effort. Plenty of room for me, my wife and our dogs.

Amazing Tent

I love this tent. Have used it several times this summer, with great satisfaction.

I searched far and wide for a tent that would fit my 6’6” frame, and found it in this tent. I live in Oregon.

Once you get the hang of setting it up and breaking it down, it’s super fast. It is incredibly lightweight. From the factory it is water TIGHT. It rained pretty heavy up in the Alpine Lakes region of Washington and inside of the tent was bone dry. I would recommend getting the titanium stakes, carbon fiber pole for the awning, and water seam sealing all from Lightheart.

I love knowing I bought a tent made in America, and for the quality I have seen so far, at a very fair price all things considered. I look forward to using this tent for years to come.

Extremely slippery floor: almost like an air hockey table. I need something to keep my sleeping pad from sliding all over
Wish there was two pockets instead of one inside the tent

Thruhiking in alpine terrain - well designed and made tent

I bought this tent after quite some research for a special trip.

2 Weeks on Europe's hardest thruhike, the GR20. I was looking for a very light 2-Person trekking pole tent that could accommodate 2 tall hikers (197cm). The usable length is was brought me to it.

It is very well thought out and makes some distinct choices and compromises to achieve the overall package. I have the 20D Silpoly version and it came seamsealed.

Some Pros:
- setup was fast (always quicker than my buddies with BA Tiger Wall UL2)
- quite windstable (50kmh+ gusts)
- dried off very quickly after rain
- awning pole is a killer feature (see the pictures)
- good ventilation for a single-wall design
- very light measured against most other tents on trail

Some Cons:
- not condensation free (but that was to be expected and it is manageable)
- bathtub floor could be higher at the vestibules
- large living space needs a large campsite too

I was initially worried about pitching it in a very rocky environment but with aluminium Y-stakes we always managed a good pitch. Only exception in the picture with 8 stone anchors - that also worked but took time.

We had everything from warm to cold weather (400 - 1800m above sea level), wind, storm, rain and hail. It all went well. The mesh doors are ideal for cross ventilation but provide less protection when water sprays up from underneath the vestibules. I will adress this with a simple modification of silpoly strips that can be velcroed on.

One recommendation is to carry seam sealer on the first trip or any trip. Ours had small leaks at the top vents that I addressed. Otherwise seamsealing was perfect.
I also recommend using a groundsheet, we used Tyvek, it is absolutely essential in rocky terrain.

Overall we were very happy with the tent and it performed as expected. Other tents may have more room in the head-area but are substantially shorter. The length is really what stood out the most right after the vestibule in porch mode that is very unique. We were able to put our packs at the foot end if we wanted them inside.
