Tarptent Dipole 1 DW vs Dipole 1 Lithium: Which Ultralight One-Person Tent Should You Buy?

Introduction

The Tarptent Dipole 1 has built a strong reputation among backpackers who want a light, storm-worthy one-person shelter that pitches with a minimum of fuss. It is offered in two versions: the Dipole 1 DW, a double-wall tent with a 20-denier polyester fly, and the Dipole 1 Lithium, a single-wall tent built from Dyneema composite fabric.

Side by side, the two tents look almost identical, and in most respects they are. The floor dimensions, the door count, the vestibule layout and the pitching method carry over from one model to the other. What changes is the material story, the weight, the amount of interior room and the price. That makes the decision unusually clean: you are choosing how much you value a lighter pack, and how much you are willing to pay for it.

What Both Tents Share

Both versions use an 84-inch floor with 36 inches of width at the head and foot ends. The floor tapers toward the middle in an hourglass shape, and that taper is the heart of the design. It allows the canopy to hold proper tension from the peak down to the corner stake points, which is why the tent can stand with as few as four stakes. Pitching with six to eight stakes is worth the extra minute if you expect wind.

Neither version is freestanding, so both rely on trekking poles or dedicated carbon poles to stand. Each has two doors and two vestibules, which gives you a place for gear on either side and a second exit if the weather turns. The footprint is small enough to slot into tight campsites that would defeat a larger shelter.

Because neither version has large, broad walls, there is little surface area for wind to catch. In gusty conditions the canopy sheds wind rather than fighting it, and that composure is one of the main reasons the platform performs well above the treeline.

Tarptent Dipole 1 DW: The Double-Wall Option

The DW is the value play. It pairs a 20-denier polyester fly with a separate inner tent and a nylon floor, and it sells for roughly $300 depending on the inner style and end strut option you choose. That price puts a genuinely storm-worthy, well-designed shelter within reach of most backpacking budgets.

The double-wall build brings two practical advantages. First, it separates you from the fly, so condensation that forms on the outer fabric is far less likely to end up on your sleeping bag or gear. Second, it is modular. You can choose a mesh inner for warm, well-ventilated trips, or a solid inner that helps hold body heat in cold conditions and keeps windblown sand and dust out of the sleeping area.

Two details are worth planning for. The tent does not arrive seam sealed, so you will need to seal it yourself or pay for a sealing service, and doing it yourself is a straightforward job. The advertised weight is 32.5 ounces, and that figure does not account for the trekking poles or dedicated carbon poles needed to pitch it. The head and foot ends use 18-inch struts to lift the canopy off the ground, peak height is 43 inches, and a zippered vent with a shock cord can be opened or closed from inside the tent without stepping out into the rain.

Tarptent Dipole 1 Lithium: The Single-Wall Option

The Lithium takes the same design and rebuilds it around Dyneema composite fabric, used for both the body of the tent and the floor. At $649 it costs more than twice as much as the double-wall version, and in exchange you get an advertised weight of 24.8 ounces.

Because the Lithium is single wall, there is no inner netting pressing in on you, so the usable interior feels a little more open than the DW even though the floor dimensions are essentially the same. The head and foot ends use taller 21-inch struts, which lift the canopy further off the ground and help keep the walls away from your sleeping bag. Peak height is 44 inches, and the layout still includes two doors and two vestibules.

Ventilation is handled differently as well. Large mesh panels at the head and foot ends move a lot of air through the tent, and they can be closed completely when a storm rolls in so that rain does not blow inside.

If the weight difference does not matter much for the trips you take, the double-wall version delivers the same shape and the same pitching experience for far less money. The Lithium is for backpackers who feel every ounce and are prepared to pay for the reduction.

Living Space and Ventilation

For a one-person tent, both versions are roomy. You can sit up, move around, and keep gear at the head and foot ends without feeling boxed in. The vestibules are large enough to hold everything you want to keep out of the weather, and having two of them means you are not choosing between your pack and your boots.

Condensation is the real dividing line. On the DW, moisture that collects on the fly stays on the fly, and the inner tent acts as a barrier between that moisture and your gear. On the Lithium, the canopy is the wall you sleep against, so the tent leans on air movement and on the taller struts to keep damp fabric away from your bag. The DW carries a slightly larger vent than the Lithium, though both give you plenty of ventilation options. Either way, you can manage airflow from inside the tent without getting out.

Weight, Packed Size, and Setup

The advertised weights are 32.5 ounces for the DW and 24.8 ounces for the Lithium, and neither number includes the poles needed to pitch either tent. Whether that gap is significant depends entirely on how you travel. For shorter trips and weekend use, the DW’s weight is easy to justify. On a long thru-hike, the lighter single-wall shelter is the version many backpackers will gravitate toward.

Setup is the same on both. Four stakes will get the tent standing, and adding two to four more sharpens the pitch in wind. The hourglass floor taper does most of the work here, and the result is a shelter that stays quiet and stable when gusts hit.

If you are new to trekking pole shelters, budget a little practice time. The Dipole rewards a careful pitch, and once the tension is right it holds up well in poor weather.

Price and Long-Term Value

At roughly $300, the Dipole 1 DW is the easier recommendation for most backpackers. It keeps a high-quality, storm-worthy design within a normal gear budget, and the modular inner options let you tune it for cold weather or dusty conditions. Add a seam sealing job to your plans and you have a complete shelter for a fraction of the cost of the Dyneema version.

The Lithium sits at $649. That is more than double the price of the DW, and the premium buys lighter materials and a little more living space rather than a different shape or a different pitching method. It is a fair trade for the right buyer, but it is worth being honest with yourself about whether the weight saving will change your experience on the trail.

Which Dipole 1 Should You Buy?

Choose the Dipole 1 DW if you want the best value in the lineup, if you like the idea of a solid inner for cold or dusty trips, and if you are comfortable sealing the seams yourself or paying to have it done. It is the version that fits the widest range of backpackers, and it delivers the same footprint, the same two-door layout and the same wind-shedding profile as its more expensive sibling.

Choose the Dipole 1 Lithium if saving weight is a priority, if you want the extra interior openness that comes with a single-wall build, and if the higher price fits your budget. You are paying for Dyneema and for ounces, not for a different tent.

Conclusion

The Dipole 1 is a design that works, and both versions share its best qualities: a small footprint, an efficient four-stake pitch, two doors, two vestibules, and real stability in wind. The decision comes down to materials and money. The double-wall Dipole 1 DW delivers the same experience for around $300, while the single-wall Dipole 1 Lithium trims the advertised weight to 24.8 ounces and asks $649 for the privilege.

If you are unsure, start with the DW. It is the lower-risk purchase, it handles condensation well, and it leaves room in the budget for the rest of your kit. Move to the Lithium when every ounce counts and the budget allows.
