DAC J-STAKE Set (12pcs)

Lightweight and wind resistance
Challenging the reconciliation of conflicting demands in a new dimension

"Designed for wind resistance suitable for use in mountainous regions throughout all four seasons"
"To provide a space where two people can live comfortably while keeping it as lightweight as possible."

We challenged ourselves to balance these conflicting demands in a new dimension distinct from existing tents.

Early in development, we calculated material weights and immediately realized that adopting lightweight tent poles—prioritizing lightness over strength—was essential. Ensuring the strength required for a mountaineering tent while using lighter poles felt like a question with no easy answer.

Drawing on my engineering experience, I racked my brains and arrived at a solution: a unique sleeve hub structure combined with a truss structure utilizing guy lines. The sleeve hub is a groundbreaking design that combines the strength advantages of both the sleeve-type and suspension-type systems—traditional tents have historically chosen one or the other. Furthermore, by integrating this with a truss structure using guy lines, we enabled the tent's strength to be enhanced according to weather conditions.

We've also prioritized livability as much as strength, making it appealing through our unique ideas. While most Japanese-brand two-person mountain tents measure less than 120 cm to 127 cm in depth, ours is generously sized at 128 cm. Combined with a width of 210 cm and height of 102 cm, this creates a spacious interior.

In addition to the main living space, a unique rear compartment serves as gear storage, providing ample space that feels no less comfortable than a two-person mountaineering tent.

Despite its exceptional performance and comfort, it achieves a minimum weight of just 1075g.
We have achieved the largest floor area possible for a two-person mountaineering tent.

The product includes the tent body, flysheet, poles, and groundsheet, offering a complete package with everything you need in one set (※2).
We also offer optional accessories to make the AX series even more robust and comfortable.

The AX-130 is a new-generation Japanese mountaineering tent designed for two people to enjoy hiking with tent camping.

※1: Equipment weight is 1265g. However, the weight of the included groundsheet (113g) is not included in the equipment weight.
※2: Pegs are sold separately.

This update includes the following improvements and changes.
・One side of the pole sleeve features a closed structure, making it easier to set up the tent.
・Compared to the initial model, we reduced the force required to set up the tent during the harsh winter season when nylon shrinks.
・We relocated the guy ropes to the flysheet to enable quicker access to the guy ropes.
・The flysheet and inner tent can now be secured with Velcro, making it easier to set up the tent with the inner tent and flysheet attached.
・We've changed the coating on the inner tent's 10D fabric to enhance its strength.
・We modified the shape of the tent pole receptacle bracket to reduce the weight of the part while also lowering the risk of the tent pole slipping out during setup.
・We enlarged the tent storage bag to make it easier to pack even frozen tents.
・The depth of the tent has been reduced from 133 cm to 128 cm.
・We have partially modified the sleeve structure.

■Close-up detail
• Features a spacious vestibule ideal for cooking and storing gear

○Starting with AX-130 Version 3.0, you can now choose from two types of inner tents.
In addition to the nylon type suitable for all seasons, a new mesh type ideal for summer has arrived.
Recommended for UL hikers seeking breathability and greater lightness. The mesh type can also be purchased individually.
※Please note that we do not sell the nylon inner tent separately.

○Large C-shaped door designed for easy access (with mesh option)
Unlike reverse U-shaped doors, you can enter and exit without fully opening the door.
On the opposite side of the entrance is a small window providing access to the rear room.

○ You can easily access the rear compartment from inside the tent.
You can store items like hiking boots and crampons that are difficult to store inside the tent.
Using the separately sold rear compartment ground sheet prevents your belongings from touching the ground directly, allowing for more comfortable use.

○Chimney-style mesh window ventilation
Nylon does not provide a complete seal, thereby reducing the risk of suffocation during heavy snowfall in severe winter conditions.
The design draws in cool air through the mesh window below the entrance and expels warm air from above.

○ The inner tent and flysheet entrance feature a convenient double-slider design.
You can open only the top to check the conditions outside.

○ The upper section is equipped with ventilation rods to enhance airflow.
It is designed to prevent rain from entering even when open.
We redesigned it to avoid getting in the way when not in use.

○ Two mesh pockets are provided on the lower left and right sides of the inner tent's short ends.
We've redesigned the pocket placement for even greater usability.
A resin ring has been added below the inner guy line attachment point to make it easier to adjust the guy line tension.

■Technical Note
○Features the high-performance DAC Featherlite NFL 8.7 tent poles
To achieve this weight without extreme functional compromise, the AX-130 poles required the use of " DAC Featherlite NFL 8.7" tubing, prioritizing lightness over strength.
However, DAC does not recommend this pole for alpine use in high winds.
Therefore, a breakthrough was essential to establish this pole as an alpine tent while using it.

The AX series incorporates the following three innovative mechanisms into the tent structure to enhance pole strength.

1. Full-Sleeve Inner Tent x Proprietary Sleeve Hub
The AX series employs sleeves for connecting the inner tent to the poles.
Compared to the hook-style (suspension-style) commonly found in recent tents, the sleeve-style structure distributes the load on the poles and suppresses pole deformation.

On the other hand, existing sleeve-style tents do not have the two sleeves connected, and their structure does not allow the two poles to effectively support each other.
In that regard, the hook-type design features a swivel connecting the centers of the two poles, creating a structure where the two poles support each other.

Arata created its own sleeve hub to combine the advantages of both sleeve-type and hook-type designs.
As shown in the photo above, two sleeves are connected via a hub, enabling the two poles to support each other despite the sleeve design.

While this structure may seem difficult to set up for entry-level users, it actually allows for quicker setup than hook-style tents since there's no need to attach each hook individually.
Furthermore, the flysheet, inner tent, and groundsheet are pre-attached, allowing for simultaneous setup—a structure offering a significant advantage during rainy weather.

2. Sleeve Hub Guy Point
The AX series features a guide line attachment point on the sleeve hub.
By crossing the poles and pegging them down as if binding them together, it is possible to rigidly connect the two poles as if they were joined by a hook-type swivel.

The sleeve hub guide line can be routed through the hole at the top of the flysheet.
The AX-130 has a large projected area on its long side, making it susceptible to wind effects from that direction.
The Sleeve Hub Guy Point (※3) is arata's unique mechanism that enhances the tent's wind resistance by pegging down the long side from the tent's top section, which experiences significant displacement.
(Using the optional emergency guideline kit is more convenient)

※3: Since no dedicated guide line is included with this unit, please purchase the optional Emergency Guide Line Kit or attach a guide rope cut to a suitable length yourself.

3. Inner Guideline
The inner guy ropes are installed on the inside of the short side of the AX series inner tent.
This serves the same function as the bracing commonly seen in prefabricated buildings for reinforcement, helping to suppress tent deformation caused by wind from the long sides.

Furthermore, the AX series allows for increased tent strength by installing an optional emergency guyline kit, though this comes at the cost of sacrificing interior space.
We recommend carrying it especially during long-distance traverses where weather forecasting is difficult, or when setting up camp at points where conditions are prone to change.

○ Rear compartment for expanding cargo space and improving wind resistance
The AX series features a rear compartment space in addition to the entrance vestibule. This space forms the cargo area while enhancing wind resistance from the rear.
X-shaped dome tents for 1-2 people are vulnerable to wind hitting the longer sides with larger projected areas.
Tents with a single-sided entrance typically feature a back panel shaped to fit snugly against the inner tent for weight reduction, but this structure makes it difficult to deflect wind, creating a direction that is vulnerable to wind.

The AX series prioritizes ruggedness and practicality over excessive lightness in its construction.

○ Distance between the ground and the flysheet
Raising the flysheet's bottom edge is a common weight-saving tactic, but the AX series prioritizes use in severe weather with heavy rain, wind, and snow, so it's set as low as possible.
It reduces the risk of wind whipping up the flysheet during strong winds with rain, drawing rain into the tent.
The AX series is also designed for use during snowfall while the rain fly remains in place. By filling the gap between the ground and the fly with snow, the AX series can prevent snow from entering the flysheet.

○ Tent color that minimizes transparency
At popular mountain campsites, it's often so crowded you could almost reach out and touch the tent next to yours. Modern tents are made of thin fabric, and if they're light-colored, you might even see the people inside faintly during the day.
The AX series features both the inner tent and flysheet in a deep gray, preventing visibility into the interior during daytime while also improving the clarity of silhouettes when lights are on at night.

The disadvantage of using a dark gray color is increased temperature inside the tent during the day, but regardless of color, spending time inside the tent during the day is difficult in hot seasons.
Therefore, the AX series prioritized privacy protection in its color settings.

○ The inner tent is available in two types: "nylon" and "mesh."
※The inner tent for this product is made of nylon.

Starting with AX Version 3.0, we have enabled the option to select an inner tent.
In addition to the all-season "nylon," a new addition is "mesh."

Nylon models, while easy to use in rain or snow, were too hot for summer use at low altitudes and were unsuitable.
Therefore, we have added a mesh version for climbers who do not use it in low temperatures.
Additionally, the mesh inner tent is now available as a standalone option. This is also available for those who already own the AX Version.3.0.

※Please note that we do not sell the nylon inner tent separately.
※The average dimensions stated in the text are based on arata's research.
※The photo shows Version 3.0. In Version 3.1, the shape of the pole sleeve is slightly different (to improve production efficiency).

■Option Parts

DAC J-STAKE Set (12pcs)
※Pegs are not included with this product. Please purchase them from the above link or provide your own.
The DAC J-STAKE is a peg that arata trusts and considers suitable for Japan's mountain environments.
The V-Shape excels in balancing penetration and holding power, firmly gripping the ground without damage from soft soil to hard surfaces packed with large stones. From an engineer's perspective, we believe no other peg offers a better balance of cost and performance.

〇Emergency Guyline Kit
※Please select Version 2.
Optional items to further enhance the strength of the AX series.
By installing the emergency guyline kit as shown in the image above, it is possible to enhance the tent's strength at the expense of internal space.
We recommend carrying it, especially when setting up a tent during long-distance traverses where weather forecasting is difficult or at points where conditions are prone to change.
