A light insulated jacket built for warmth, breathability and easy movement - makes a great mid or outer layer for cool weather activity.

Rab's Cirrus Flex Jacket is the ideal layer for getting active outdoors, with a 'slim' cut that will fit nicely underneath a waterproof shell.

Made using very breathable Hyperlite ripstop fabric outer and lining fabric, it's filled with Cirrus featherless insulation and has Thermic stretch fleece
panelling at the sides that gives you extra mobility while keeping you covered. 

It has large, useful pockets inside and out, and the left hand pocket doubles as an integrated stuff sack making it very easy to take with you wherever you go.

  • Hyperlite ripstop outer and lining fabric
  • Cirrus (powered by 3M) featherless insulation
  • Thermic stretch fleece panelling
  • YKK Vislon front zip with internal storm flap
  • 2x YKK zipped hand pockets (Left doubles as stuff sack)
  • 2x interior drop-in pockets
  • Lycra elasticated cuffs, hem drawcord

Cirrus™ (powered by 3M Featherless technology) uses technical, water resistant fibres in a “down-like” structure to deliver the same warmth for its weight as 600 Fill Power duck down.
It lofts freely, compresses well when packed
and is robust and durable. Its moisture resistance, warmth when wet and speed
of drying are very high: superior even to Rab's Hydrophobic Down.

Breathable, Insulated, Packable, Pockets, Storm Flaps
Excellent breathablity

Men's Rab Clothing Size Guide

Measuring tips

Take your actual body measurements as they are more accurate than measuring over your clothes or shoes.

CHEST: Measure around the fullest part of your chest, making sure to keep the tape under the arms and around your shoulder blades.

WAIST: Measure around the smallest part of your waist (natural waistline).

HIPS: Stand with your heels together and measure around the fullest part.

INSIDE LEG: Measure from the top of your inner leg, along the inside seam to the bottom of your leg.

Disappointed - Faulty Zip

After so many good buys from Rab this jacket fell short. The pocket zip to my jacket regularly entangled with the inner surplus material and just after 12 months broke the teeth on the zip.

Lightweight, looks the part and does the job! ideal for walking in autumn & spring as its thin while still keeping the wind at bay. Rab coats are definitely worth the money!
