FAQs

Is this jacket suitable for winter sports?

While it is waterproof, it is a shell layer without insulation. You would need to wear a mid-layer underneath for warmth in cold climates.

What does 2.5L mean?

It refers to the construction: a durable outer fabric, a waterproof membrane, and a protective "half-layer" coating on the inside, which makes it lighter than 3-layer jackets.

Does it have a helmet-compatible hood?

The hood is designed for general hiking and outdoor use; it is adjustable, but may not fit over large climbing helmets.

Are the materials sustainable?

Yes, the jacket is constructed from 100% recycled ripstop fabric and uses a PFC-free water-repellent treatment.

Can I use this for everyday commuting?

Absolutely. Its technical performance makes it an excellent, lightweight option for urban commuting or wet-weather travel.

Troubleshooting

Water soaking into the outer fabric

The DWR (Durable Water Repellent) treatment is likely worn off. Wash the jacket and tumble dry it on low heat to reactivate, or apply a fresh DWR spray.

Feeling damp inside the jacket

Ensure underarm vents are open during high-intensity activity. If heavy rain continues, check that all zippers are fully closed and the hood is properly adjusted.

Pros and Cons

  • Eco-friendly construction using 100% recycled materials
  • Effective underarm ventilation system
  • Lightweight and packable 2.5-layer design

Setup, Compatibility & Care

To maintain the integrity of the DRYEDGE membrane, keep the jacket clean by washing it in a machine at a low temperature (usually 30°C) with a mild, non-detergent technical soap. Always close all zippers before washing. Because the jacket features a PFC-free DWR coating, the water-repellent performance will diminish over time; tumble drying on a low setting or using a technical spray-on re-proofer can help reactivate or restore the DWR finish. Avoid using fabric softeners or bleach, as these can permanently damage the technical properties of the waterproof membrane.
