HyperDRY™ Water Resistant Down
ALLIED’s HyperDRY™ Water Resistant Down allows the Alpine 850 Lite Down Jacket to provide extreme performance in unpredictable conditions. Regular untreated down can wet-out and struggle to retain warmth when wet, HyperDRY™ down is incredibly hydrophobic, helping prevent the down structure from collapsing due to absorbing water. This allows the down to retain its loft and warmth for longer when damp, while also allowing it to dry much quicker.
The treatment of the down works in the same way as traditional DWR’s while being developed to be as sustainable as possible. HyperDRY™ is entirely fluorocarbon-free and has been designed to utilise less water and chemical processing compared to traditional treatments.
850+ fill power. Maximum warmth at minimal weight
The fill power measurement in down tells us how much loft and strength the down clusters have, and therefore how much air (and warmth) they can trap. With a 850+ fill power the down utilised in the Alpine 850 Lite provides exceptional warmth for the weight, utilising larger down clusters that are capable of trapping more air. This high fill power means the Alpine 850 Lite provides greater warmth compared to other jackets of the same weight, making it the perfect choice for when maximum insulation at minimal weight is essential.
PERTEX® QUANTUM ECO fabric. Windproof and water repellent weather protection
Windproof, soft to the touch, incredibly packable and 100% recycled. PERTEX® QUANTUM ECO is constructed in a tightly woven structure to provide lightweight windproof protection and trap still air inside the jacket. This allows the down insulation to fully loft and retain its warmth.
A PFC-free durable water repellent (DWR) finish allows the fabric to shed light rain and snow, allowing the jacket to provide weather protection in adverse conditions.
The fabric is constructed using highly abrasion resistant nylon ripstop, incorporating reinforcement yarns to provide durable resistance to tearing, helping the fabric to withstand harsh mountain environments.
