The Ultimate All-Mountain Winter Shell The Arc'teryx Men’s Beta Insulated Jacket is designed for those who need a single, high-performance layer that can handle the unpredictability of winter in the mountains. By integrating insulation directly into a technical hardshell, Arc'teryx has created a piece that simplifies your layering system without sacrificing protection. The exterior is constructed from a durable, highly breathable 2-layer GORE-TEX fabric, ensuring you stay dry during heavy snow, rain, and high-output activities.

Inside, the jacket utilizes Coreloft™ Continuous synthetic insulation. This mapped insulation is strategically placed to provide maximum warmth in the core while maintaining a slim, non-restrictive profile in the arms and shoulders. Unlike down, Coreloft™ retains its loft and insulating properties even if it becomes damp, making it the ideal choice for humid or mixed-weather environments. With a helmet-compatible StormHood™ and a refined, articulated fit, the Beta Insulated Jacket is equally at home on a technical ascent as it is on a cold morning at the local trailhead.

• 2L GORE-TEX Construction: Provides 100% waterproof and windproof protection while maintaining excellent breathability for active moisture management.
