If you find yourself rummaging frantically in your climbing pack because it feels way too light for you to have not forgotten something, rest assured that your ultralight Mammut Women's Microlayer Half-Zip Jacket is still safely nearby. At an absurdly low weight of just 2.8 ounces, the Microlayer passes easily for air when stowed in a pack, but you'll thank Mammut later when you unclip it from your harness halfway up a multi-pitch climb to help get you through a drizzly spell.

  • Entire jacket stows easily in chest pocket and can strap to a climbing harness for easy access
  • Adjustable hood helps you balance coverage with visibility
  • UPF 50+ rating means you don't have to worry about harmful rays on sunny but breezy days
