Rab Cirrus Flex 2.0 Women’s Vest – Synthetic Insulated, Windproof & Water-Resistant | Citadel, X-Small

Overview

The Rab Cirrus Flex 2.0 Women’s Vest is designed as a compact core-warming layer for cold days on the trail, walls, or slopes. It blends warmth with resilience, offering a windproof shell and a down-like feel from synthetic insulation. This vest focuses on real-world use, delivering warmth and comfort without promising guaranteed outcomes.

Warmth that behaves like down, with a twist

The vest uses Primaloft Silver Luxe insulation, a 100% recycled material that mimics the loft of down while staying warm when damp. The result is a light, lofty sensation in a compact package, ideal for shifting weather on alpine routes or misty ridges. Expect a comfortable core layer that remains reliable when conditions change.

• Down-like warmth with synthetic resilience in damp conditions
• 100% recycled materials align with environmental goals
• Warmth retained when wet, reducing chill during transitions

Weather protection done with care

The shell is crafted from Pertex Quantum, a windproof and lightweight fabric. A fluorocarbon-free DWR treatment helps water bead on the surface, keeping you drier as you move through spray or light showers. The fabric remains breathable to avoid overheating during exertion.

• Windproof, lightweight shell blocks cold gusts
• Fluorocarbon-free DWR for water resistance
• Breathable performance for ongoing activity

Freedom of movement for mountain days

Thermic fleece side panels follow your movements, offering a full range of motion whether you are climbing, skiing, or trekking. Micro baffles with stitch-through construction help maintain the vest’s shape, while semi-elastic armholes reduce rubbing and improve comfort.

• Stretchy side panels support dynamic movement
• Micro baffles provide stable warmth distribution
• Semi-elastic armholes minimize irritation

Practical design for real-world use

The Cirrus Flex 2.0 fits slim to layer under shells or over mid-layers. A cinch-cord at the hem keeps the vest in place when wearing a harness or backpack. It can be packed into its own pocket, and there is a loop to clip it to a harness or bag for quick access during climbs or backcountry days. The garment is part of Rab’s Cirrus range and emphasizes recycled components where possible.

• Cinch hem for secure fit with harnesses
• Self-storing packability for travel and climbing
• Conscious materials with recycled content in the Cirrus line

Versatility beyond the mountain

Beyond mountaineering use, the vest offers a sleek silhouette that pairs well with a shell on cold mornings or a base layer on cool afternoons. The combination of warmth, wind resistance, and a light, packable feel makes it a practical option for hikers, climbers, and ski enthusiasts who value a capable, easy-to-wear layer.
