Developed in collaboration with Samaya athletes, the ALPINIST2 ULTRA has been designed to meet the demands of mountaineering. Its single-wall Dyneema_X™ design offers weather protection (20,000 mm) and ventilation (40,000 g/m²/24h) far superior to market standards. What's more, its Carbon_X™ internal poles structure keeps weight down while facilitating assembly and disassembly.

TECHNOLOGIES

Biosourced Dyneema

Biosourced Dyneema® is a more sustainable version of conventional Dyneema®, manufactured from renewable raw materials, mainly forest industry residues, rather than fossil resources.

This material is based on a production process in which ethylene, the key ingredient in Dyneema® , is obtained from plant biomass instead of petroleum. This approach significantly reduces the carbon footprint while maintaining the outstanding performance of conventional Dyneema®: extreme tensile strength, lightness, waterproofing and durability.

Certified ISCC (International Sustainability & Carbon Certification), biosourced Dyneema® is part of acircular economy approachand CO₂ emissions reduction, offering a more responsible alternative without compromising on performance.

TENT WALLS

Dyneema_X™

Samaya adapts its composites according to use. Dyneema_X TM combines Dyneema® filaments with an ePTFE membrane, offering waterproofness (20,000 mm), breathability (40,000 g/m²/24h) and lightness. The microporous structure of ePTFE evacuates vapor while blocking water, while Dyneema® ensures high mechanical strength and low water absorption.

POLES

Carbon_X™

Samaya has developedCarbon_X™ poles to offer a solution specifically suited to ultra-light tents. Designed entirely in carbon, both in sections and junctions, they avoid the stresses associated with assembling different materials. Their draped carbon-fiber construction reduces the risk of splinters in the event of breakage, and facilitates repairs in the field. Finally, the contrast between the red color of the poles and the black of the joints makes it easy to visually check that they fit together correctly, reducing the risk of breakage during use.

TENT FLOOR

Dyneema Composite Fabric (DCF)

Samaya chose Dyneema® Composite Fabric for its tent floors because of its exceptional properties. This laminated textile, composed of 90°-crossed UHMWPE fiber filaments and two layers of Mylar®, offers very high mechanical strength and limits tearing in the event of perforation. In addition to its performance, this material is easily repairable, prolonging the life of Samaya products.
