Show Description

A minimalist jacket that stands up to maximalist weather. The stripped-back Mammut Masao Light jacket is made of lightweight fabric and folds down small in a stuff sack to hide away in your backpack. But it still provides bomber protection from rain and wind, thanks to the internal DryTechnology Performance waterproof-breathable membrane.

  • YKK Aquaguard front zipper keeps rain out.
  • Helmet-compatible hood has a reinforced brim and adjustments for visibility.
  • Zippered hand pockets are compatible with your climbing harness or backpack hipbelt.
  • Underarm zippers for venting when you're working hard.
  • Pre-shaped sleeves promote range of motion for climbing.
  • Asymmetric cuffs add coverage with elastic on one side for a snug fit.

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.

Waterproof with fully taped seams
Fabric active breathability

The rate at which a waterproof breathable fabric expels moisture when the inner surface is moist from perspiration. Values under 8,000g/m2/24h provide low performance, 20,000g/m2/24h provide moderate performance and values over 30,000g/m2/24h provide high performance.

Venting Underarm zips
Pockets 2 front zippered

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 Hip-length
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.
