Arc’teryx Women’s Beta High-Performance Insulated Waterproof Jacket

The Beta Insulated Jacket is your ultimate defense against harsh alpine conditions, engineered to excel in cold, wet environments while adapting seamlessly to your every move on the mountain. Designed for all-mountain versatility, this shell combines cutting-edge technology with practicality to meet the demands of technical hikes, ski tours, or unpredictable weather shifts.

At its core lies Coreloft Continuous insulation—a synthetic layer that traps warmth efficiently even when damp—ensuring you stay cozy during prolonged exposure to snow or rain. Paired with a PFAS-free GORE-TEX ePE fabric, it delivers uncompromising waterproofing and breathability without compromising on eco-conscious materials. This innovative fabric shields you from storms while allowing moisture to escape, keeping you dry whether you’re ascending icy ridges or descending through slushy trails.

For dynamic adventures, the Beta’s features prioritize comfort and control. The helmet-compatible StormHood adjusts effortlessly to fit under or over headgear while maintaining peripheral visibility, so you can focus on navigating rugged terrain without distraction. Strategic pit zippers provide instant ventilation during intense activity like skinning or climbing, preventing overheating on exertion-heavy days. A two-way front zipper adds flexibility for harness compatibility during belaying or backpacking trips, eliminating layering frustrations.

Practicality meets safety: multiple organized pockets keep essentials secure and within reach—perfect for multi-day treks—while an embedded RECCO reflector acts as an invisible safeguard in case of emergencies. The updated design introduces a softer interior liner for all-day wear comfort and enhanced breathability compared to traditional shells.

Whether you’re chasing first tracks in freezing temperatures or enduring relentless mountain downpours, the Beta Insulated Jacket stands out with its blend of performance-driven innovation and user-focused details. Unlike heavier insulated options that sacrifice mobility or eco-friendly alternatives that compromise on waterproofing, this jacket balances technical excellence with sustainability—making it ideal for those who demand reliability without environmental trade-offs.
