Description

The Advanced Mountain Kit is made with unparalleled precision for the world’s best mountain athletes. Our Summit AMK Superlight Sleep System is the next step in the evolution of alpine bags. It offers a wide fit so you can wear multiple layers while you sleep, meaning the bag itself requires less insulation for a lighter overall kit.

  • Wide cut allows user’s apparel insulation to loft, which reduces the amount of insulation needed in the bag
  • Combination of 1000 fill ProDown™ and a wide cut creates a multi-temperature system: 30°F/-1°C as a standalone bag; 0°F/-18°C when used as part of the AMK apparel-layering system
  • Shell fabric made with Spectra® ripstop for ultra-lightweight durability
  • Water-resistant exterior helps keep insulation dry
  • Center half zip keeps the bag light and compressible while maintaining access to the tie-in point
  • Thin, down-insulated hood and footbox provide warmth
  • Cinchable hood and collar help seal out the cold
  • Dyneema® compression stuffsack included
  • Down fill: Lofty down insulation maintains warmth in cold conditions.
  • DWR - Water repellent: A durable finish to allow for water beads on the surface of water repellent materials, preventing the fabric from saturating
  • Sizes : REG, LONG
  • Temp Rating : 30°F/-1°C (0°F/-18°C when sleeper is wearing AMK apparel)
  • Total Weight : reg - 2 lbs 5 oz (1045 g) / long - 2 lbs 8 oz (1135 g)
  • Stuffed Size : reg - 8.27'' x 15.75'' (21 cm x 40 cm) / long - 12.2'' x 18.9'' (31 cm x 48 cm)
  • Internal Length : reg - 78'' (198 cm) / long - 84'' (213 cm)
  • Max User Height : reg - 6' (183 cm) / long - 6'6'' (198 cm)
