Arc'teryx - Alpha IS Jacket - Men's

The Alpha IS Jacket - Men's from Arcteryx is an insulated GORE-TEX® hardshell for the harshest alpine conditions. This is a single-layer solution for severe alpine environments. The GORE-TEX® outer delivers durable waterproof, windproof, breathable protection. Thermatek™, a DWR treated continuous filament synthetic, insulates without absorbing moisture. The combination results in a jacket providing comprehensive weather and thermal protection at a weight 18% lighter than the equivalent midlayer and hardshell system.

ThermaTek™ Insulation
Exclusive to Arc'teryx, ThermaTek™ is a continuous filament, synthetic insulation that is treated with DWR (Durable Water Repellent) to make it highly hydrophobic, which means that it repels moisture very efficiently. The lofty insulation is then laminated to a backing fabric to ensure an even distribution and insulation.

• Machine wash in warm water (30°C).
