Tarptent Mesospire 2 Review: A $300 Trekking Pole Tent Built for Two

Introduction

Tarptent’s Mesospire 2 is a new single-wall trekking pole tent for 2025, and it takes a familiar hexagonal silhouette and turns it into a genuinely roomy two-person shelter. It is priced at $300 USD, which lands in a comfortable middle ground for backpackers who want a lightweight tent without paying premium money for it.

The pitch is refreshingly straightforward. Six stakes are enough to hold the tent, and adding two more for the apex guy lines brings the total to eight for a tight, taut setup. That is worth noting, because trekking pole tents are not always easy to dial in, and this one comes together quickly.

What stands out most is the balance between interior space and packed weight. The Mesospire 2 weighs just under 40 ounces as configured with the extra apex stakes, and that figure can come down further by leaving two stakes at home and swapping the carbon fiber end struts for trekking poles.

Who the Mesospire 2 Is For

This is a shelter for two backpackers who want to sleep side by side rather than head to toe. The floor measures 86 inches long and 52 inches wide and stays fully rectangular, with no taper toward the foot end, so two 25-inch wide pads fit comfortably without pressing hard against the bathtub walls.

It also works as a very generous one-person tent. Solo hikers who value space to spread out gear and move around will find plenty of it here, though that room comes with a larger footprint and more fabric than a dedicated solo shelter.

Design and Pitch

The structure follows the hexagonal shape used on the Stratospire, adapted here into a single-wall design. Two opposing corners carry 18-inch carbon fiber struts that lift the ends of the tent and open up the interior. Those struts are optional: the Mesospire 2 accepts two sets of trekking poles, one pair for the main body and another pair at the ends in place of the struts.

Both doors can be rolled back, which widens the opening and makes the tent feel considerably more open. Rolling the doors back does relax the ridge line, so staking out the apex guy line is the better choice when you want the tent at its most rigid.

Living Space and Ventilation

Peak height is 47 inches, and the corner struts add another 18 inches of rise at the ends. The result is a tent where two people can sit up comfortably at the same time, and where the distance from your face to the fly fabric is generous enough to matter when condensation is a factor. Being 86 inches long, there is room at both the head and foot ends, and gear is less likely to end up pressed against a damp sidewall.

Ventilation is one of the best thought-out parts of the design. Each corner has an overlapping fabric panel that releases from a plastic clip and rolls up to expose no-see-um mesh, then holds in place with a mitten hook clipped around the guy line. In fair weather that opens the sight lines and moves a lot of air through the tent. In wind and rain, the panel drops back down and clips shut for full storm coverage. Two peak vents add another path for air, with an extra zipper pull on the YKK number three Aquaguard zipper so you can crack them open.

Inside, there are hooks along the ridge line for a drying line and two pockets set high off the floor for small items like a headlamp or lip balm. Two doors and two vestibules mean nobody has to climb over anyone else to get in or out.

Fabric and Weather Worthiness

The fly and main body are a single layer of 20-denier nanoripstop polyester, a fabric that resists sagging when it gets wet while staying light and strong. The floor uses 30-denier Nylon 66, which is durable for its weight and packs down small.

The hexagonal geometry should help in rough weather. Each panel is relatively small, so there is less surface area to catch wind and act like a sail, and the stake-out points create strong, well-distributed tension. The Stratospire platform this design draws from has a long track record in exposed conditions, which is a reasonable signal for how the Mesospire 2 is likely to behave in strong wind and heavy rain.

Main Strengths

Three things stand out. First, the pitch: six stakes minimum, eight for a taut setup, and it goes up fast without the fiddling that often comes with trekking pole shelters. Second, the space: a 52-inch wide rectangular floor and a 47-inch peak, with corner struts that raise the ends so two people can sit up and change clothes without elbowing each other. Third, the ventilation: the roll-up corner panels are a small detail that makes a real difference to how the tent feels inside, both in clear weather and in the middle of a storm.

At $300 USD, the tent also reflects careful construction. The details, from the high-set pockets to the extra zipper pull on the vents, suggest a shelter built by people who spend time in them.

Things to Consider Before Buying

The main trade-off is size. For a solo hiker, this is a large shelter with a large footprint, and anyone counting grams for a minimal setup may prefer something smaller. A roomier solo tent is a wonderful thing until you are trying to find a flat spot for it on a crowded alpine platform.

It is also a single-wall tent. That keeps the weight down and simplifies the pitch, but it means the fly is your sleeping space, and ventilation management matters more than it does with a double-wall design.

Finally, the tent needs a full set of stakes to reach its tightest pitch. Six will hold it, eight plus the two apex guy lines will make it rigid, and leaving stakes at home to save weight means accepting a slightly softer structure.

Buying Advice

If you are shopping for a two-person trekking pole shelter that pitches easily, sleeps two 25-inch pads comfortably, and stays under 40 ounces, the Mesospire 2 is worth a serious look at $300 USD. It suits backpackers who prioritize living space and quick setup over the absolute minimum packed weight, and the flexible ventilation makes it usable across a wide range of conditions rather than just mild summer nights.

Solo hikers who want a large, comfortable shelter and are not worried about the extra footprint will also get a lot out of it. If your priority is the smallest and lightest possible solo setup, a smaller shelter will serve you better.

Conclusion

The Mesospire 2 brings a proven hexagonal shape into a single-wall, two-person package at an approachable price, with a pitch that is easy to get right and ventilation that adapts from fair weather to full storm cover. The trade-offs are straightforward: it is big for one person, it relies on a full stake set for its stiffest pitch, and it is a single-wall design. For two-person trips, that combination is easy to like.
