Regulus is the brightest star in the constellation Leo, and is visible almost year-round.

  • Therm-a-Rest blankets are lighter and more packable than most conventional sleeping bags, and offer better freedom of movement and temperature regulation in summer weather.
  • Baffles run down the sides of the blanket, creating a seal around your mattress. The elasticized foot box wraps around the end of your mat, trapping warmth and providing room to move.
  • Therm-a-Rest blankets attach directly to almost any mattress with the included Loop Kit.
  • EraLoft™ is a proprietary blend of three synthetic fibers that provides superior warmth, loft and durability. Short, soft fibers trap warmth, long fibers create loft and medium-length fibers provide structure and water resistance.
