Regulus™ Blanket 40F | 4C | Synthetic

The Regulus Blanket partners with your mattress to create a sleep system offering excellent freedom of movement and temperature regulation in temperatures as low as 40F (4C). Synthetic eraLoft insulation offers warmth and loft that performs in all-weather conditions. A shaped footbox and insulated baffles create a secure connection with your mattress and prevent drafts. The included loop kit allows your blanket and mattress to function as one throughout the night.

  • Comfortable: Blanket Construction offers free movement and temperature regulation.
  • Warm: Insulated Baffles and an elasticized foot box create a seal around your mattress that keeps drafts at bay.
  • Versatile: Included Loop Kit allows a wide range of attachment options.
  • Synthetic: Light, compressible eraLoft™ synthetic insulation stays warm and dry in wet conditions.

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.
