  • Insulated with high-loft, water-resistant 725-fill-power duck down on top of the sleeping bag for warmth, light weight and compressibility
  • PrimaLoft® Synergy synthetic insulation on the bottom works a lot like down, but performs better than down when exposed to wet weather
  • With a lower-limit European Norm (EN) rating of 27°F, the Matrix III is a versatile bag for lightweight adventures into the mountains
  • Downproof and wind-resistant, the densely woven synthetic shell is light, compressible and tough; silky soft lining is also downproof and highly breathable
  • Durable Water Repellent finish on shell causes water to bead up and roll off
  • 4-baffle trapezoid footbox is wide in toe area and narrow at the heels for comfort that does not compromise warmth
  • Protecting the head and neck, the hood features 5 baffles and an anatomic fit to provide warmth and low weight
  • Alpine Fit features a semi-tapered mummy profile with a tapered lower leg section to maximize warmth and minimize weight without restrictiveness
  • Single antisnag draft tube (along the 3/4 length zipper) and semi-floating neck collar drape comfortably, blocking the escape of heat and sealing out drafts
  • Mountain Equipment Matrix III sleeping bag comes with a lightweight stuff sack and mesh storage bag
  • European Norm (EN) is an independent third-party temperature rating, allowing accurate comparisons across brands with other EN-rated bags
