PRODUCT DESCRIPTION

The ALPINIST2 ULTRA was designed for, and used on some of the most difficult climbs in the world:

First winter solo of Cerro Torre (Patagonia) — Colin Haley
First ski descent of Nanga Parbat (Pakistan) — Tiphaine Duperier, Boris Langenstein, David Goettler (paragliding)
First ascent of Kimshung (Nepal) — François Cazanelli, Giuseppe Vidoni
Ascent of the Goretta Pillar, Fitz Roy (Patagonia) — Colin Haley
Attempt on the north face of East Jannu (Nepal) — Léo Billon, Benjamin Védrines, Nicolas Jean
Attempt on K7 Central (Pakistan) — Tom Livingstone and Tad McCrea

Pushing your limits at high altitude requires maximum effort and great efficiency. Your tent then becomes a refuge, a place to recover before the final push to the summit.

The double-layer internal Carbon_X™ pole design allows you to complete the tent setup from the inside and to take it down quickly as needed.

The walls of the ALPINIST series tents are steep to facilitate snow shedding. Its minimal floor area of 2.5 m² and the end door make setup on small ledges simple and efficient.

This freestanding tent withstands winds of up to 120 km/h in wind tunnel tests.

Dyneema® is 15 times stronger than steel while being so light that it floats on water. Compared to other fabrics for alpine tents, Dyneema® is 40% stronger than aramid (such as Kevlar) and 500% stronger than polyester at the same weight (tenacity in g/den). In the most extreme mountain conditions, where wind, snow, and other elements threaten to tear your tent, choosing a Dyneema® reinforced fabric provides the comfort and safety essential in these environments.

The Dyneema® Waterproof Breathable Composite™ single-wall material combines Dyneema® filaments with an ePTFE membrane. The microporous structure of the ePTFE releases moisture while blocking water, while Dyneema® provides high mechanical strength and low water absorption. This Dyneema® Waterproof Breathable Composite™ fabric is certified to 20,000 mm of water column and offers superior protection against rain and snow, while handling a maximum moisture of 40,000 g/m²/24h.

The groundsheet is made of a 34 g/m² Dyneema® Composite Fabric that makes it waterproof, compact, light and highly tear-resistant. It has the same waterproof rating of 20,000 mm as the tent walls.

Two Carbon_X™ poles with a diameter of 8.4 mm support the ALPINIST2 ULTRA tent, weighing only 199 g and folding down to 40 cm in length. The poles have visual indicators that allow you to check that the joints are properly engaged thanks to their red bodies and black internal joints.

The reflective guy lines with removable Dyneema® cores make it easier to locate your tent on the way back from the ascent.

8 DAC aluminum J.Stakes(F) weigh just 60 g and are suitable for conditions at lower altitudes.
The interior floor area of 2.5 m² is sufficient for two mountaineers to sleep in, while remaining compact and easy to set up on steeper terrain.

The interior space is optimized with a width of 120 cm and a length of 210 cm, as well as a maximum interior height of 105 cm.

The awnings above the door and rear window protect these openings when they are used for better ventilation and prevent rain from entering.

The single door has two zipper pulls allowing it to be opened like a window as needed.
Tent body / Poles + Pegs weight ratio: 69 % / 31 %

The tent body packs down easily to a volume of 2.8 L in a compression bag made of Dyneema® Composite Fabric, weighing just 675 g at minimum weight. If you leave the compression bag at home and take only the main fabric, it will weigh 590 g.

The poles and pegs have their own storage bags and weigh just 265 g together. Taking only the poles weighs 200 g.

The optional Alpinist2 nylon footprint adds 245 g and has a volume of 0.8 L when needed.

The two Carbon_X™ poles quickly snap into each corner inside the tent and are held in place by Velcro straps.

The removable reflective guy lines with a Dyneema® core are installed using a bowline or by untying a knot (see video tutorial). Essential for ensuring wind resistance, they can be removed to save about 30 grams. They do not stretch when wet and feature an easy-to-use adjustment mechanism.

WHAT THE EXPERTS SAY

Tom LIVINGSTONE

Mountaineer and climber

« I’m really impressed with the tent - great job Samaya. I think it’s an excellent product.
I believe the ALPINIST2 ULTRA is the ultimate alpine tent for cutting-edge mountain adventures. It’s incredibly lightweight and gives reliable shelter thanks to the materials and construction.

The design is simple and strong, with only the essential features. Details have been well-thought-out: it’s easy to put up in bad snowy weather and whilst wearing gloves.

Lightweight alpinism at high altitude means having faith in your equipment. It means every gram counts and is totally necessary. I’ve used these types of tents for 14 years, and tested prototype Samaya versions for three years. I can now say: I think this tent is the business! »

Francesco RATTI

Mountaineer

« Having put the ALPINIST2 ULTRA tent through its paces on recent expeditions to Nepal and Patagonia, I can say it's a real game-changer for serious adventures in the mountains. Its extreme lightness is a dream when every gram counts, and the breathability is outstanding. Its sturdiness is impressive – it stood strong against the most ferocious Patagonian winds! »

Fred DEGOULET

Mountaineer

“After testing and approving the ALPINIST2 ULTRA on several trips, notably on the ridge traverse around the Mer de Glace, I can say that this tent is part of my mountain gear, whether as an amateur or with my clients.

I would recommend this tent with my eyes closed.”

Bio-based Dyneema®

Bio-based Dyneema® is a more sustainable version of classic Dyneema®, made from renewable raw materials, primarily derived from forestry industry residues, rather than fossil resources.

This material relies on a production process where ethylene, the key ingredient of Dyneema®, is obtained from plant-based biomass instead of petroleum. This approach significantly reduces the carbon footprint while maintaining the exceptional performance of conventional Dyneema®: extreme tensile strength, lightness, water resistance, and durability.

Certified by ISCC (International Sustainability & Carbon Certification), bio-based Dyneema® is part of a commitment to a circular economy and the reduction of CO₂ emissions, offering a more responsible alternative with no compromise on performance.

TENT WALLS

Dyneema_X™

Samaya adapts its composites based on their intended use. Dyneema_X™ combines Dyneema® filaments with an ePTFE membrane, offering waterproofing (20,000 mm), breathability (40,000 g/m²/24h), and lightness. The microporous structure of the ePTFE wicks away vapor while blocking water, while the Dyneema® provides high mechanical resistance and low water absorption.

POLES

Carbon_X™

Samaya has developed Carbon_X™ poles to provide a solution specifically suited for ultra-light tents. Designed entirely from carbon, including both the sections and the junctions, they avoid the constraints associated with assembling different materials. Their draped carbon fiber construction reduces the risk of splinters in the event of breakage and facilitates field repairs. Finally, the contrast between the red color of the poles and the black of the junctions allows for visual verification that they are correctly fitted, thereby reducing the risk of breakage during use.

TENT FLOOR

Dyneema Composite Fabric (DCF)

Samaya has chosen Dyneema® Composite Fabric for the floors of its tents due to its exceptional properties. This laminated textile, composed of UHMWPE fiber filaments crossed at 90° and two layers of Mylar®, offers very high mechanical resistance and limits tearing in the event of a puncture. In addition to its performance, this material is easily repairable, thus extending the lifespan of Samaya products.
