Cowboy camping is an art, and whether you're sleeping out by a cactus or in a grove of pine trees, you need something to keep you warm. Bring along the Therm-a-Rest 45-Degree Synthetic Space Cowboy Sleeping Bag to stay toasty through the summer months. Therm-a-Rest zoned the eraLoft insulation so that it maximizes warmth, with 65% of the insulation in the top of the bag, and used water-resistant fill that won't lose its insulating properties if you happen to get the bag damp. SynergyLink Connectors ensure your bag stays put on your pad, reducing the need for back-of-bag insulation, and shaving ounces off in case you decide to take it backpacking. For further weight-reduction, the Space Cowboy replaced some additional insulation with a ThermaCapture lining to reflect your body heat as you sleep. When you're enjoying your coffee from the comfort of your sleeping bag--and inevitably spill--the liquid will roll off thanks to the DWR treatment that makes it easy to clean it off and go on with your trip.
