Rab Women's Firewall Alpine Jacket | Ultralight Waterproof Hooded Shell – Tempest Blue (Med)

Lightweight protection for unpredictable alpine days

When weekend plans turn to rain-swept ridgelines or exposed scrambles, you need a layer that travels light but performs when the weather shifts. The Rab Women’s Firewall Alpine Jacket delivers ultralight protection with a compact footprint, making it easy to pack in a daypack or harness pocket for quick access on the trail.

Its Pertex Shield 3-Layer fabric is bonded to a windproof, 100% recycled nylon shell. The result is a thin, durable layer that balances weather resistance with breathability, so you stay more comfortable as you move through changing conditions.

Why this jacket stands out

• Waterproof rating: 20,000 mm with a breathable rating of 20,000 g/m², helping you stay dry while you stay active.
• Materials: Fluorocarbon-free DWR on a 20D recycled nylon shell, aligning with eco-conscious design choices.
• Packaging and weight: ultra-light at about 10.1 oz, designed to fold into a corner of your pack without bulk.

Design for movement and practicality

• Regular fit with fully articulated sleeves ensures comfortable layering and unrestricted movement on climbs or scrambles.
• Helmet-compatible hood with a flexible peak offers solid coverage under a climbing helmet or cap.
• Watertight YKK AquaGuard zippers cover the front, chest pocket, and ventilation zippers under each sleeve for reliable seals.
• Underarm vents and adjustable cuffs with hook-and-loop closures assist with temperature control and fit.
• Dual-sided rear hem adjustment helps seal out drafts when you’re crouched or braced.

Real-world use cases

Ideal for “summertime on the ridgeline” where weather can flip quickly—rain showers, light hail, or gusty winds—while remaining light enough for long approaches. It pairs well with base layers for cool mornings and mid-day warmth if the sun returns. The packable design means it can ride along in a lightweight pack until the moment you need it.

Consider it a dependable outer layer for alpine hikers and climbers who value warmth balance, mobility, and simple weather protection without extra bulk. The jacket’s fabric, zippers, and hood are designed to deliver consistent performance across varied alpine scenarios.

Durability and care: The jacket is designed for repeated wear in wet and windy environments. Clean with mild soap and air-dry; reapply DWR as needed to maintain water repellency.

Size and fit: Regular fit with articulated sleeves allows layering a fleece or soft shell beneath for cold mornings or high-elevation treks.
