Thermarest Space Cowboy 45 Small Sleeping Bag

Perfect for smaller campers, Thermarest’s Space Cowboy 45 Small Sleeping Bag is shorter than the regular version, making it lighter and warmer as there is less airspace for the user to have to heat up. 220 grams of eraLoft provides the insulation, with its synthetic, hollow fibre construction trapping warm air without soaking up moisture. The insulation is laid out in a zoned format which puts more material where it is needed most so that the bag’s performance is maximised without adding unnecessary weight.

SynergyLink Connectors allow the bag and Thermarest sleeping pad to be joined together to ensure that they both stay in place during the night whilst quilt and blanket loops provide the means to add extra layers of insulation to the bag if required. The included compression sack makes it easy to pack the bag away small for carrying and there is also a storage sack that allows the bag to loft when not in use.


  • eraLoft™ insulation: Efficient and compressible, water-resistant synthetic fill uses hollow fibres to reduce weight without sacrificing warmth
  • SynergyLink Connectors: Integrate the bag with a mattress for optimal comfort and efficiency; removable for versatility
  • Zoned insulation: Maximises warmth and saves weight by intentionally placing fill where needed most. Placing 65% of the fill on top and 35% on the bottom keeps the Space Cowboy lightweight without sacrificing warmth
