Our Verdict
The Rab Cirrus Flex Insulated Jacket is an impressively lightweight and versatile piece perfect for year-round use. Weighing just 387 grams in a medium size, this jacket combines warmth, breathability, and packability in one streamlined design. The updated larger baffles and high-loft PrimaLoft Silver RISE insulation provide excellent warmth while maintaining a low profile, making it ideal for layering in colder conditions or as an outer layer in milder weather.
The jacket's performance on the trail is outstanding. The Thermic stretch fleece side panels enhance mobility and breathability, allowing for comfort during more intense activities. The recycled Pertex Quantum outer fabric is lightweight and durable, offering protection without compromising environmental responsibility. The jacket’s fit is slim but accommodating, making it comfortable for all-day wear, whether climbing, hiking or just enjoying the outdoors.
Practical features like the YKK zips, articulated sleeves, and integrated storage pocket with a clip-in loop make the Cirrus Flex a well-rounded choice for hikers who need reliable, adaptable insulation.
