The Tarptent Stratospire Li pitched within the Japanese Sierras above Lake Tahoe.

It units up shortly, stays taut in tough circumstances on account of DCF development and Tarptent’s proprietary constructed-in tensioners, and has sufficient chops for yr spherical use. I examined the Stratospire Li throughout an eight-day trek by means of Montana’s Absaroka-Beartooth Wilderness in the summertime/fall shoulder season. Climate circumstances have been everywhere in the map, which means I had the chance to watch this shelter’s efficiency throughout clear (however chilly) nights, mild rain, mist, mild snow, and driving wind.

The Stratospire Li options an octogonal eight-panel design and is about $80.00 costlier than the Duplex. It weighs 26 oz (737.1 g). The fly can arrange independently from the inside.

The offset trekking poles, big vestibules, and roomy inside are just some of the options that make the Stratospire Li such an expertly designed shelter.

This can be a roomy, robust, nicely-designed shelter. Tarptent rightly lauds the Stratospire Li’s efficiency in windy circumstances.. The eight-panel design minimized noise and flap on an extended, chilly, windy night time excessive within the Beartooths. The ridgeline remained tight (with assistance from the 2 optionally available stakes and tie-outs), and the built-in line tighteners have been taut after ten hours of excessive-velocity gusts. Briefly, Montana threw various wind at this shelter, and it didn’t budge. I used to be tenting with a gaggle of ten hikers, and I used to be one of many few who handed an uneventful and comfy night time.

Photograph: Tarptent The Stratospire Li’s stability is a perform of its octagonal design.

The ground of the Stratospire Li is rectangular, however the fly is octagonal, and the trekking poles are offset. This could require a little bit of considering throughout setup, notably in case you are in a decent state of affairs or your spot isn’t optimum. DCF material has little or no stretch, which means your stake angles and placement have to be a bit extra exact than with a silnylon shelter. Ensure to observe Tarptent’s setup video. After viewing that and pitching the shelter a number of occasions in a yard, I had no drawback getting the shelter pitched in beneath two minutes.

PitchLok corners are a singular Tarptent aspect: they supply stability and construction to the eight-panel design. The carbon fiber struts fold flat for stowing the shelter and are detachable if wanted.

Tarptent bonds then sews the seams on its DCF shelters. Whereas that is an extremely strong and waterproof method of becoming a member of Dyneema Composite Materials, it isn’t as aesthetically pleasing as a seen-then-bonded development.

The shelter units up with trekking poles in a deal with-down configuration (though Tarptent sells an adaptor to permit the handles to face up). I’ve used a silnylon Tarptent for years and by no means apprehensive about poking a gap in my shelter with the carbide tip of the trekking pole, however one thing concerning the almost seven-hundred greenback price ticket of the Stratospire Li gave me pause each time I set it up. The excellent news is, do you have to occur to (carelessly) puncture the Stratospire Li, the DCF development makes it a lot simpler to patch than silnylon.

A grommet cradles the tip of a trekking pole in the usual setup configuration. Tarptent sells an optionally available “handle down” attachment if the considered probably punching a gap in your $700.00 tent is an excessive amount of to bear.

The shelter is roomy, with a 45 in (114.three cm) vast and 86 in (218.four cm) lengthy bathtub flooring. The apex peak is 45 in (114.three cm) tall. This area accommodates two commonplace sized sleeping mats with ease (or one normal mat and one large mat with barely much less ease). There’s loads of room to take a seat up and alter garments, even for tall hikers. Two doorways and two vestibules make sharing the shelter as cozy because it will get, in addition to optimizing airflow and views for these dramatic campsite days.

Loads of room to stretch out within the Stratospire Li. The shelter simply accommodates two commonplace sized mats however is mild sufficient for a solo hiker with luxurious and area in thoughts.

The vestibules are gigantic, greater than giant sufficient to accommodate cooking, moist gear, packs, canine, or youngsters. Tarptent sells an attachment to show this huge area right into a separate compartment do you have to be touring with a toddler.

One aspect impact of those giant vestibules is that the sting of the fly is sort of removed from the bath flooring after zipping the doorways. The space eliminates the “up-splash” drawback (in heavy rain, water can splash up from the puddle created by the fly) sometimes skilled by smaller Tarptents.

These vestibules are so giant I couldn’t match one into an image, even with the usual large-angle lens of an iPhone. Loads of room to retailer gear and prepare dinner if wanted, and that also leaves you one entire vestibule on the opposite aspect.

Tarptent loaded the Stratospire Li with considerate options: flooring and apex adjustment straps, storm sealed zippers, zipper flaps for drip safety, and magnetic closure loops to roll the outer fly up and out of the best way.

Tensioners on the corners of the ground are half of a bigger constructed-in adjustment and tensioning system that permits for exact pitches even in much less-than-splendid campsites.

Storm sealed zippers. This tent will hold you dry in raging storms.

The zipper flap additionally snaps up out of the best way with a magnet. Keep in mind to do that earlier than unzipping, or you’ll have a caught zipper.

The Stratospire Li is loaded with properly-thought-about options similar to a magnetically fastening snap to scale back zipper drip.

I really like this magnet system, and I want it was additionally on the inside mesh door. As an alternative, that door rolls up with a clip and loop system, one thing I sometimes discovered difficult to control with chilly or gloved arms.

The clip and loop system on the inside bug internet is useful however much less simply manipulated within the chilly than the magnet snap system on the outside fly.

The Stratospire Li is a cumbersome tent when rolled and saved. The carbon fiber struts within the Ziplock corners are detachable should you really feel like stuffing, however Tarptent recommends rolling to enhance the lifespan of the DCF. I discovered the stuff sack to be giant sufficient that rolling was not a lot of a ache, notably in case you comply with the producer directions. That being stated, the tent did really feel chunky in my pack and required that I re-assume my common pack organizational system.

The inside pockets on the corners of the mesh doorways felt small. Cumbersome, mild gadgets reminiscent of a Buff or stuff sacks tended to fall out all through the night time. Storing smaller, heavier gadgets like a headlamp or a pocket knife are the perfect use for these pockets.

Tarptent sells an non-compulsory strong wall inside for very chilly or windy circumstances. Including a strong wall inside would beef up an already storm-resistant tent, and provides it some 4-season potential. Nevertheless, I’d be involved that the Stratospire Li’s shallow pitch angle might give it some issues with heavy snow masses, although the DCF won’t stretch underneath load and can shed snow higher than silnylon.

Additional testing is required, notably to see how the tent fares in winter circumstances, and compared to the Zpacks Duplex. Till then, this can be a nicely-designed, properly-constructed, thoughtfully realized shelter with sufficient toughness to face up to a variety of seasons and circumstances. Giant, cozy, and secure whereas remaining ultralight, it gained’t allow you to down—assuming you possibly can abdomen the worth tag.

The Stratospire Li is secure even with out the non-compulsory ridgeline guyline (proven right here in orange, and never included with buy). If you add that, this shelter can stand up to some spectacular circumstances for its weight class.
