HYPER DRY™ Stay Warm. Stay Dry.

Our HyperDRY™ water-resistant down technology ensures the Anti-Freeze XT delivers exceptional performance in even the harshest conditions. Unlike traditional down,, HyperDRY™ down is highly hydrophobic, repelling moisture and maintaining its loft. This means you stay warmer for longer, even when wet, and dry out faster.

HyperDRY™ is not only effective but also sustainable. It's completely fluorocarbon-free and requires less water and chemicals during processing compared to traditional treatments.

Windproof PERTEX® QUANTUM

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.

The fabric is lightweight, packable and soft to the touch. A fluorocarbon-free DWR finish allows the fabric to shed light rain and snow, allowing the jacket to provide weather protection in adverse conditions.
