FAQs

Is this jacket suitable for winter mountaineering?

While highly protective, this is a lightweight jacket. It is better suited for hill walking and trekking than harsh alpine winter environments requiring heavy-duty shell protection.

Can I wear a helmet under the hood?

The hood is designed for general use. While it is adjustable, it may not fit over all climbing helmets; check the fit before heading out.

How do I know if it is waterproof?

The Proflex technology is a 3-layer construction rated for waterproof protection. Provided the garment is clean and the DWR is maintained, it will keep you dry in heavy rain.

Is the jacket machine washable?

Yes, but use a mild technical detergent and ensure the zippers are closed. Avoid bleach or fabric softeners.

What is the best way to pack the jacket?

The fabric is flexible enough to be folded neatly or stuffed into a compression sack without causing damage to the membrane.

Does it have pit zips for ventilation?

The Firewall Light model focuses on the breathability of the Proflex material itself; this specific model does not include traditional pit zips.

Troubleshooting

Water soaking through the outer fabric

The DWR finish has likely worn off. Wash the jacket and re-apply a technical waterproofing spray, then tumble dry on a low setting as directed by the care label to reactivate.

Condensation building up inside the jacket

While breathable, the jacket cannot move moisture instantly. Ensure you are layering appropriately for the level of activity and open the jacket periodically if sweating heavily.

Zipper sticking

Clean the zipper tracks with a soft brush to remove grit or debris and ensure the fabric baffle is not caught in the teeth.

Pros and Cons

Pros

  • Excellent balance of breathability and waterproofing
  • Highly packable for long-distance treks
  • Articulated sleeves allow for unrestricted movement
  • Stiffened hood peak improves visibility in storms

Cons

  • Lightweight construction is more prone to abrasion damage
  • Regular fit may be baggy for those preferring athletic cuts
  • Limited pocket options compared to heavier technical shells

Setup, Compatibility & Care

To ensure the longevity of the jacket, avoid using harsh detergents that can degrade the waterproof membrane. When cleaning, wash in a front-loading machine with a technical garment cleaner on a gentle cycle. Always zip up the main and pocket zippers before washing. Re-waterproofing sprays may be applied to the exterior after several seasons of heavy use to maintain the DWR (Durable Water Repellent) performance. Store the jacket in a cool, dry place and avoid hanging it in direct, prolonged sunlight to prevent fabric degradation.
