Show Description

When you pare down to capitalize on fleeting alpine conditions and ephemeral mixed lines, the Patagonia M10 is suitably spare. The 3-layer ultralight nylon compresses into the jacket's inner pocket and can be clipped on your harness. The simplified design has a single chest pocket and has eliminated underarm zips and handwarmer pockets. Minimalism is extended into the narrow tape used on welded seams and slimmed down hook-and-loop closures at the cuffs. The slim fit works as a technical shell over light-to-medium weight layers.

  • Supple 3-layer nylon ripstop fabric uses a Deluge® Durable Water Repellency (DWR) coating.
  • Watertight coated zipper has a DWR finish.
  • Helmet-compatible hood has a laminated visor to keep your vision clear. Adjusts with a single pull.
  • Soft microfleece lined neck and chin.
  • Jacket fits inside zippered chest pocket, with reinforced carabiner loop for clipping it to a pack or harness.
  • Cuffs close tight with hook-and-loop closures.
  • Drawcord hem seals out elements.

Fabric waterproof rating

The standard test for waterproof fabrics uses a standing column filled with water. The figures given are the water column height. A rating of 3,500mm or higher can be considered waterproof. The higher the rating, the more durable the waterproof fabric will be over time.


Waterproof garments use waterproof-breathable technologies and are fully seam-taped. Water-resistant garments use waterproof-breathable technologies but their seams are not taped. Water-resistant garments repel water and protect against wind but are not made of waterproof fabric.

A windproof garment does not allow any air to permeate the fabric. A garment with windproof panels has panels of fabric that are totally windproof, but the rest of the garment may not be windproof. A wind-resistant garment resists some wind, but not as much as a garment that is windproof.

Length Below hip
Durable water repellency

Usually referred to as DWR. A treatment made to fabrics that causes water to bead and run off instead of soaking through.
