Product Information

Full details

The Mountain Equipment Paiyu Insulated Jacket is designed for adult mountaineers and alpinists who prioritize warmth-to-weight performance during remote expeditions. It features high-quality down insulation and a windproof DRILITE LOFT shell, offering exceptional heat retention and packability for cold, technical environments. While it excels as a standalone piece in fair weather or a mid-layer during extreme conditions, its technical materials require careful maintenance to preserve down loft and water resistance.

Extended Product Information

FAQs

Is this jacket waterproof?

It is highly water-resistant and windproof, but it is not classified as a fully waterproof hardshell. It is intended for dry cold or as a mid-layer.

Can I wash the Paiyu in a standard washing machine?

You can use a front-loading machine, but only with a mild, down-specific detergent on a gentle cycle. Avoid top-loading machines with agitators.

How do I store the jacket long-term?

Store it hanging in a closet or in a loose-fitting mesh storage bag to allow the down to stay lofted.

Does the hood fit over a climbing helmet?

Yes, the Mountain HC hood is designed to be helmet-compatible and fully adjustable.

What should I do if a feather pokes through the fabric?

Gently pull the feather back into the jacket from the inside. Do not pull it out, as this can enlarge the hole in the fabric.

Troubleshooting

Down insulation appearing flat or clumped

Tumble dry the jacket on a cool setting with clean tennis balls to fluff the down and redistribute the fill.

Water soaking through the shell fabric

The DWR finish has likely worn off. Wash the jacket with a technical cleaner and apply a spray-on DWR treatment.

Zipper sticking or catching on fabric

Clear any loose threads from the zipper path and ensure the storm flap is pulled away when zipping.

Pros and Cons

Pros

  • Excellent warmth-to-weight ratio for long expeditions
  • Highly packable for space-constrained gear lists
  • Strategically placed pockets work well with climbing gear
  • Completely windproof shell material
  • Helmet-compatible hood provides superior coverage

Cons

  • Requires specific down-care washing techniques
  • Shell material needs regular reproofing to maintain water resistance
  • Higher price point compared to synthetic alternatives
  • Down insulation loses loft if compressed while wet

Setup, Compatibility & Care

To ensure the jacket performs as intended, adjust the hem drawcords and sleeve cuffs before starting your ascent to prevent cold air ingress. For layering, the Paiyu works best over a base layer but is designed to sit comfortably underneath a hard shell for survival situations.

Care instructions:

  • Always store the jacket uncompressed in a cool, dry place to maintain down loft.
  • Use a dedicated down-specific soap to clean the garment; avoid standard detergents which can strip natural oils.
  • Tumble dry on a low heat setting with tennis balls or dryer balls to redistribute the down clusters evenly.
  • Regularly refresh the DWR (Durable Water Repellent) coating on the outer shell when water beads less effectively.
