Rab Cirrus Flex Mens Jacket 2025

Throw on for an alpine start or layer in the deep winter, the Cirrus Flex Jacket offers year-round versatility and low-bulk warmth.

Light and packable, the Cirrus Flex is the ultimate year-round synthetic insulation. It’s versatile enough to accompany you on any mountain adventure, either as an outer in the warmer months or as an insulating layer when the temperatures drop. With its hallmark fleece side panels that breathe on the climb and reduce bulk, it’s easy to layer and offers superb freedom of movement. Re-engineered with high-lofting PrimaLoft® Silver RISE insulation, it features larger baffles that allow the insulation to loft more and retain more heat. Delivering exceptional warmth for weight, the insulation recovers quickly when wet, making it the ideal choice for your hikes, climbs, and scrambles in damp weather.

• PrimaLoft® Silver RISE insulation resists clumping when wet, keeping you warm in damp weather.
• The Cirrus Flex’s signature Thermic™ stretch fleece panels offer mobility and breathability.
• Larger baffles allow insulation to loft more and trap warmth more effectively.
• We’ve shaved weight by using a lightweight, 20D Pertex® Quantum fabric.
• Multiple secure pockets, one of which doubles up as an integrated storage pocket.
