HyperDRY™ Water Resistant Down
ALLIED’s HyperDRY™ Water Resistant Down allows the Alpine 850 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. 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 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 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.
