FAQs

Is the Rab Cirrus Flex Insulated Hooded Jacket waterproof?

No, the jacket is water-resistant thanks to its Pertex Quantum shell fabric and Fluorocarbon-Free DWR finish. It will repel light rain and snow, but it is not designed to be fully waterproof for heavy downpours. For sustained heavy precipitation, we recommend pairing it with a waterproof outer shell.

Can I wear this jacket all year round?

Yes, its versatile design makes it suitable for year-round use. It can serve as a lightweight outer layer in cooler conditions during warmer months or as an effective insulating mid-layer when temperatures drop significantly.

What type of insulation does it use?

The jacket uses PrimaLoft Silver RISE synthetic insulation. This high-performance synthetic insulation is designed to offer excellent warmth-to-weight, high loft, and superior performance in damp conditions compared to traditional down.

How should I wash and care for my jacket?

Machine wash cold on a gentle cycle using a technical cleaner for insulated garments. Do not use bleach or fabric softeners. Tumble dry on low heat with tennis balls to restore loft, or air dry completely. Refer to the care label for detailed instructions.

What is the fit like?

The jacket has a 'slim fit.' This means it sits closer to the body to reduce bulk and allow for efficient layering under an outer shell. It is designed to maximize mobility and thermal efficiency during active pursuits.

Are there pockets on this jacket?

Info needed: Please refer to product specifications or images for details on pocket configurations.

What activities is this jacket best suited for?

The Rab Cirrus Flex Insulated Hooded Jacket is ideal for a range of mountain activities including climbing, general outdoor use, trekking, and mountaineering, where versatility, warmth, breathability, and freedom of movement are crucial.

Troubleshooting

Jacket feels too tight or restrictive during movement.

The Rab Cirrus Flex has a 'slim fit' designed for layering and active use. Ensure you selected the correct size. If it feels restrictive, consider sizing up if you prefer a looser fit or plan to wear bulkier layers underneath. The stretch fleece panels are designed for movement, so check if any underlying layers are snagging.

Jacket doesn't seem to be providing enough warmth.

While very warm for its weight, synthetic insulation works best when combined with appropriate layering. Ensure you have a good base layer and consider the overall temperature and wind conditions. The fleece side panels, while breathable, will allow some airflow; if static in cold, windy conditions, an outer shell is recommended.

Water beads less on the surface; jacket wets out quickly.

The jacket features a DWR (Durable Water Repellent) finish, which will diminish over time. This indicates the DWR needs to be reactivated or reapplied. Wash the jacket with a technical cleaner as described in the 'Care' section, and then apply a spray-on or wash-in DWR treatment specifically designed for technical outerwear.

Jacket has an unpleasant odor after use.

Synthetic insulation can sometimes retain odors. Regular washing using a technical outdoor garment cleaner, as outlined in the 'Care' section, will help. Ensure the jacket is completely dry before storing it, as dampness can exacerbate odors. Avoid using fabric softeners, which can trap odor-causing bacteria.

Pros and Cons

Pros

  • Excellent warmth-to-weight ratio for effective insulation without bulk.
  • Maintains insulating properties even when wet, unlike traditional down.
  • High breathability and freedom of movement due to fleece side panels and articulated design.
  • Highly versatile for use in various conditions and as an outer or mid-layer.
  • Made with recycled materials and fluorocarbon-free DWR, enhancing sustainability.
  • Very packable and lightweight, ideal for fast-paced mountain activities.

Cons

  • Slim fit might not be comfortable for all body types or those preferring a looser style.
  • Water-resistant, not fully waterproof, limiting protection in heavy rain.
  • Fleece side panels, while breathable, may offer less wind protection than the main body.
  • Under-helmet hood may feel snug if not worn with a helmet or if a larger head size.
  • Designed primarily for active outdoor pursuits, making it potentially less ideal for purely static, very cold environments.

Setup, Compatibility & Care

Setup

There is no complex setup required for the Rab Cirrus Flex Jacket. Simply don it over your base layers or mid-layers. Adjust the hood for a snug fit, especially if wearing an under-helmet hood, to maximize warmth and protection. The articulated sleeves are designed to move with you, so ensure the cuffs are comfortable.

Compatibility

This jacket's slim fit makes it highly compatible with various layering systems:

  • Base Layers: Wear it over a moisture-wicking base layer for optimal performance in active pursuits.
  • Outer Shells: It easily fits under a waterproof or windproof outer shell when facing harsher weather conditions, enhancing your overall insulation.
  • Helmets: The specialized under-helmet hood is designed to fit snugly beneath climbing or cycling helmets, providing warmth without compromising helmet fit or vision.

Care

Proper care will extend the life and performance of your jacket. Always refer to the care label inside the garment for specific instructions.

  1. Washing: Machine wash cold on a gentle cycle with a technical wash designed for insulated garments (e.g., Nikwax Tech Wash or Granger's Performance Wash). Avoid using standard detergents, bleach, or fabric softeners, as these can damage the insulation and DWR finish.
  2. Drying: Tumble dry on a low heat setting with a few clean tennis balls to help fluff the synthetic insulation. Ensure the jacket is completely dry before storing to prevent mildew and maintain loft. Air drying is also an option, but may take longer.
  3. DWR Re-application: Over time, the fluorocarbon-free DWR (Durable Water Repellent) finish may wear off. You can restore its water repellency by applying a spray-on or wash-in DWR treatment after washing, following the product's instructions.
  4. Storage: Store the jacket uncompressed in a dry, well-ventilated area to maintain the loft of the insulation.
