Introduction

The Tarptent Aeon Li is one of the lightest solo (1-person) ultralight backpacking tents available. Made with Dyneema Composite Fabrics (DCF), the Aeon is a single-wall design featuring a zippered side-entry with a vestibule. The Aeon requires 4-7 stakes and is pitched with a single trekking pole.

See my review of the Tarptent Notch Li, which discusses some of the features that the Notch Li has in common with the Tarptent Aeon Li, including PitchLoc corners, Dyneema Composite Fabrics, and magnetic door closure tabs.

The following video provides an in-depth analysis of the Tarptent Aeon Li:

Commentary

What’s Unique about the Tarptent Aeon Li?

The market for lightweight solo tents weighing less than two pounds is quite crowded, comprised of dozens of both single- and double-wall designs from both cottage and larger manufacturers.

While it’s tempting to use the metric of weight for delineating product categories, it’s probably more appropriate to look at functional metrics when comparing products to each other.

In that context, these features characterize the Tarptent Aeon Li:

• 1-person capacity.
• Trekking pole-supported structure.
• Fully-enclosed shelter (i.e., includes integrated walls and floor).
• External vestibule.

These features allow us to narrow the product category and  excludes shelters requiring shock-corded pole sets, 2+ person capacity shelters, and floorless shelters such as tarps and pyramids.

Other important criteria include:

• Single-wall design.
• Dyneema Composite Fabric (DCF) materials.

That leaves a limited number of shelters meeting these functional criteria, with the most obvious competitor being the ZPacks Plexamid.

So what makes the Tarptent Aeon Li unique among this field of competitors?

1. Carbon fiber support struts.

The two back corners of the tent are each supported by two carbon fiber struts in an inverted-V configuration (Tarptent calls this a “PitchLoc” corner). A third (vertical) strut along the midpoint of the back wall, combined with the PitchLoc corners, help create a vertical wall along the back of the tent.

The presence of the struts creates the effect of a raised canopy, thus minimizing the chance that your sleeping bag will contact the lower edges of the sidewalls. A conventional pyramid design achieves the same effect without the struts – it just requires a larger canopy and larger pitched footprint. Thus, the geometric benefit of the struts is their ability to allow the tent to pitch with a smaller footprint (i.e., stakes closer to the tent).

The most impactive benefit of the strut system (and specifically, the PitchLoc corners), is that the PitchLocs create triangular structural elements that make the tent more wind resistant and more resistant to deformation as a result of snow loading. The difference in wind resistance and snow loading capability between a conventional pyramid shelter and the Tarptent Aeon is noticeable. It makes me wonder why manufacturers of conventional tarps and floorless pyramids aren’t incorporating structural elements into their designs. Maybe we will someday see tarps and pyramids incorporating the PitchLoc elements brought to market by Tarptent.

2. Carbon fiber peak strut

A carbon fiber strut situated horizontally at the peak of the tent, when combined with the vertical support pole (e.g., a trekking pole), creates a “T”-shaped structural element. When tension forces from the front and rear corner guylines are exerted on the T, the T provides resistance to torsional motion that allows the tent to be supported without the need for a front guyline. This type of structure is in contrast to typical pyramid designs, which require the front corners to be situated well in front of the top of the support pole. You can thus pitch the Aeon with a wide, nearly-vertical front opening (when both sides of the vestibule are rolled away) for expansive views and no guyline tripwires.

3. Precision design, cut, and sew (treat each of these individually)

The Tarptent Aeon Li is designed by a talented engineer (Henry Shires) who has an acute understanding of material properties (including DCF) and structural design. As such, the cut-and-sew (and bonding) processes have already taken into consideration a careful analysis of force distribution and aesthetic quality, resulting in a finished product that not only looks beautiful (when pitched properly), but also remains surprisingly stable in response to high wind and snow loads (considering that this is a one pound shelter).

Strengths

• Generous interior volume for sitting up, moving around, stowing gear, and avoiding sleeping bag contact with sidewalls of shelter.
• Well-ventilated: includes perimeter mesh around bathtub floor, two large (adjustable) interior vents, full front mesh door, rollaway vestibules, and peak vent.
• Resistant to wind and snow loading, owing to structural elements formed by carbon fiber struts (total of 6 throughout shelter), and adjustable height.
• Resistant to heavy rain and moderate spindrift, due to adjustable pitch height, bathtub floor, and overlapping vestibule doors.
• Magnetic loops that secure zippered door and overlapping vestibule doors are much easier to use than toggles or hook-and-loop straps.
• Peak strut allows the tent to be pitched without a front guyline, so when the vestibule doors are rolled back there are unrestricted views and no guyline to trip over.
• Vestibule peak provides several inches of overlap over vertical front mesh tent door, so rain doesn’t enter tent if vestibule is open/rolled away (unless there’s wind driving rain towards the inside of the tent).
• The generous vestibule is large enough for an expedition pack and gear.
• Downward sloping mesh from top of bathtub floor to bottom of shelter canopy keeps condensation droplets from gathering on the shelter floor.
• PitchLoc structures at back corners reduce footprint size, so the tent can be pitched in more compact spaces that pyramids of similar interior usable volume.
• Dyneema composite fabrics (DCF) fabrics are easy to repair, maintain tension in cold and wet conditions, and provide a high tear-strength-to-weight ratio.
• DCF fabrics may be more condensation-resistant than nylon and polyester fabrics because of lower material emissivity.
• Seam strength and strong, non-stretch fabrics combined with longer, stronger tent stakes, allow for staking the tent at extremely high levels of tension (20+ pounds per stake), which dramatically improves its wind resistance.

Limitations

• Magnetic loops that secure doors could be extended with a pull-tab for easier one-handed operation, especially with cold-weather gloves or mittens.
• Hook-and-loop patches on overlapping vestibule doors are not as easy to use as a zipper, but generous overlap and bottom clip (that clips both doors together) provide good wind and rain protection.
• Setup and configuration are quite easy but requires some geometric adjustments if pitched on uneven ground (as do most pyramid-style designs) to maintain proper tension between the stake-out points and shelter peak.
• Struts prevent the tent from being packed horizontally inside a backpack. Removing the struts is possible, but requires extra time when pitching and striking the tent.
• Dyneema composite fabrics (DCF) fabric used in the canopy is a lighter weight fabric (0.51 osy) that is prone to puncture if the shelter is pitched near sharp twigs or poky desert plants.

Compared To

Tarptent Aeon vs. Floorless Pyramid

• For similar interior volume, the Aeon requires a smaller footprint.
• The Tarptent Aeon with the integrated single-wall inner tent is a lighter combination than a pyramid tarp with a separate inner tent.
• A pyramid tarp with a separate mesh inner tent is better at managing condensation under most circumstances. A pyramid tarp with a separate fabric inner tent is better at managing cold winds and spindrift.
• A pyramid tent is typically easier to pitch but requires more stakes than the Aeon to provide similar wind stability.
• The Tarptent Aeon is better at managing heavy snow loads.
• The Tarptent Aeon pitches with no support pole in the sleeping area.

Tarptent Aeon vs. Double-Wall Tent

• Tarptent Aeon is lighter.
• Tarptent Aeon is simpler to set up and take down.
• Double-wall tents generally provide better condensation management.

For a double-wall tent that has a single side entrance, and single vestibule, check out the REI Quarter Dome SL 1, which I discuss in this video, or my review of the Tarptent Notch Li.

Tarptent Aeon vs. A Dual-Trekking Pole Supported Shelter

• Tarptent Aeon may be simpler to pitch, and lighter since it’s built around just one support pole.
• Tarptent Aeon may be the better option for users who do not use trekking poles, or who may only use one. If you’re not a trekking pole user, you can purchase a 4.2 oz pole (fixed length) from Tarptent, or an adjustable carbon fiber pole from Ruta Locura (I recommend a 3-section 0.450 pole with max length of 48-49 in). The max height you can pitch the Aeon is about 47 in (199.4 cm), but a slightly longer pole is useful if the ground is uneven.
• A dual-trekking pole shelter may be more wind-stable than the Aeon, but this is highly dependent upon the shelter.
• A dual-trekking pole shelter may offer better livability in terms of wider floor area, dual side entrances, and dual vestibules.

For a dual-trekking pole shelter, see my review of the Tarptent Notch Li.

Tarptent Aeon Li (DCF) vs. Shelters Made with Other Fabrics

• DCF may be more resistant to the formation of condensation over a wider temperature range due to DCF having a lower emissivity than nylon or polyester.
• DCF doesn’t stretch as much as nylon or polyester and tends to be more wind-stable.
• DCF’s lack of stretch allows it to maintain tension across a wide range of temperatures and moisture content than nylon or polyester, so once the tent is tensioned properly, it’s not likely to sag over the course of a cold, wet night.
• DCF manufacturing requires high levels of precision in terms of engineering design, fabric cut and sew, and seam bonding, so mistakes in manufacturing are magnified in the form of uneven stress distribution across fabric panels and seams that can lead to flapping in the wind and structural failure.
