In the backpack it weighs less than a one-liter water bottle. Then it opens, takes out a carbon structure and becomes one 2.2 square meter double wall self-supporting tent. It is the new X-Dome Pro 1+ from Durston, a company that designs ultralight equipment in the Canadian Rockies, and on the declared scale it stops at 780 grams. The manufacturer presents it as the lightest double-walled self-supporting tent in the world.
The configuration that Durston calls “typical,” with bags and four stakes, comes to 825 grams. Always very little, simply a few grams closer to the tent that you actually carry on the trail.
The trick to the weight is mostly in the Dyneema
A large part of the diet comes from materials. The outer canvas and the floor are made of Dyneema Composite Fabricin the 0.55 and 0.67 versions respectively, while the structure uses Easton carbon fiber tubes and joints. Dyneema is a fibre ultra high molecular weight polyethylene, UHMWPEa material known above all for its very high strength-to-weight ratio. Durston claims its fabrics weigh about half as much as traditional ultralight materials used in tents, absorb very little water and don’t sag when wet.
Here the adjective “ultralight” describes the scale well, but the rest of the environmental story a little less. Dyneema remains a high-performance polymer material. The manufacturer of the material declares that from 2020 bio-circular raw material will be incorporated into the Dyneema Composite Fabric according to a system of mass balance. It is an interesting element, without magically transforming a technical tent into a natural or biodegradable product. In the mountains, after all, durability and the possibility of using the equipment for a long time count for much more than a well-attached green label.
780 grams without sleeping inside a stamp
The X-Dome Pro 1+ delivers 2.2 square meters of internal surfacereaches 1.08 meters in height and measures up to 2.30 meters on the diagonal. To the side there is a 0.85 square meter vestibule where you can leave your backpack, wet gear and boots which, after a few days of walking, should have a room of their own.
The double wall separates the internal chamber from the external sheet and therefore from the bulk of the condensation. Pitching can also start directly from the tarp, leaving the interior protected while pitching the tent in the rain. The structure is completely self-supporting and, according to Durston, can remain standing even without mandatory pegs; Trekking poles and guy ropes can be added when the weather stops cooperating.
Durston claims to have successfully tested the X-Dome Pro 1+ in winds above 100 km/h using guy ropes and additional supports with trekking poles. However, it is the manufacturer himself who puts the brakes on: the tent was created mainly for one use three seasons and recommends caution well before approaching the structural limits.
The record remains a very well-defined claim
Even the definition of “lightest in the world” deserves its own stake. Durston specifically talks about self-supporting and double-walled tents. There are lighter models supported by trekking poles and single-wall tents, where some of the structure and protection from condensation is sacrificed on the altar of grams. The company itself acknowledges this in the product FAQs. The record, therefore, concerns that precise combination of characteristics and for now remains a declaration by the manufacturer, not a ranking certified by an independent body.
The price quickly brings everything back to earth. On the official website the The X-Dome Pro 1+ costs $849 and is currently out of stock. It’s not exactly the tent to buy because you forgot the Decathlon opened before camping. Here you pay above all for the extremes of a compromise: having a true self-supporting structure, double wall and a decent internal space whilst continuing to count the weight in hundreds of grams.
For those who travel through mountains for days, every half kilo removed from the backpack can have a very concrete meaning. For camping twenty meters from the car, probably less. However, the X-Dome Pro 1+ manages one interesting thing: brings a category of tents under one kilogram that until recently required much more visible compromises.
