The Rab Infinity 300 Sleeping Bag is big on warmth, not on weight. This flyweight wonder weighs in at only a pound and a half, yet insulates amazingly effectively thanks to high-grade, high-loft goose down insulation and the featherweight Pertex Quantum GL fabric.

  • Super high-loft 850-fill down insulation delivers the best warmth-to-weight ratio on the planet
  • Lightweight Pertex Quantum GL fabric optimizes the down's position in place around the body for more efficient warmth
  • Dry bag compression stuff sack keeps your bag compact and protected from nasty weather
  • Anti-snag zipper tape won't leave you stuck in your bag when nature calls late at night
  • Trapezoidal baffle-chamber design with angled foot box ensures even, full loft with no cold spots
  • Internal collar with hooded drawcord lets you seal in warmth
  • Mummy design for maximum thermal efficiency
