What's in a Name?

Here in the Western States, Rattlesnakes are common and dangerous. Sidewinders got their name for being sidewards-moving rattlesnakes, that only make contact with the sand in two small places on their body. This helps them move quicker and stay cooler by lifing their bodies off the hot sand. Side-sleepers, much like Sidewinders, make contact with the ground primarily in two places, the hips and shoulders. We developed the Sidewinder bags specifically to provide more comfort for side-sleepers, with strategically placed insulation to provide more comfort and warmth regardless of what position you wind up in.
