Arc'teryx Men's Beta Insulated Jacket

The Beta Insulated Jacket (Men’s) from Arc'teryx is a technical waterproof shell integrated with synthetic insulation, engineered for cold, wet mountain environments where a traditional shell may not offer enough warmth. It combines Arc’teryx’s trusted 2-layer GORE-TEX® construction with strategically mapped Coreloft™ synthetic insulation to provide a unique hybrid of weather protection and thermal performance suitable for ski touring, winter mountaineering, and prolonged outdoor excursions. The outer fabric uses 40-denier GORE-TEX® ePE for waterproof, windproof, and breathable protection, with a durable finish that resists abrasion. Fully sealed seams, a helmet-compatible StormHood™, and a two-way front zipper ensure robust weather defense and versatility across conditions where rain, snow, and cold converge. Inside, lightweight Coreloft™ insulation delivers balanced warmth while maintaining flexibility. Unlike down, the synthetic insulation retains loft and thermal performance even if exposed to moisture, making the jacket more dependable in unpredictable winter conditions. Pit vents provide additional airflow control during higher-output sections such as uphill approaches or ski skinning. The fit is articulated for movement and layered use, with room to accommodate baselayers or midlayers underneath without feeling restrictive. Thoughtful features like an embedded RECCO® reflector support backcountry safety and reflect the jacket’s focus on technical outdoor use. Overall, the Beta Insulated Jacket is designed for users who want an integrated insulation and shell solution that performs reliably in cold, wet, and demanding winter conditions.
