For many years, Nemo has dominated the market of sleeping bags made for sleepers on their sides, however Big Agnes stepped up to the game recently with the new Sidewinder. There’s a lot to be said about the bag. It’s big, comes with a unique zipper designed to be away from your face when you lie down and a large hood that provides an excellent cover regardless of the position you sleep in and a cushion (via synthesized insulation) on the hips and feet as they are key contacts with the ground for people sleeping on their backs. If you’re prone to tossing and turning during the night, the design is far more useful than a typical mummy’s bag, and is a worthy competitor for that Nemo Disco above.
What is the difference between the Sidewinder in comparison to what is the Nemo Disco? The most notable difference is the design that is the Big Agnes is slimmer in terms of size, with 61 inches across shoulder and 55 inches around the hip (the Nemo is 64 and 59 inches in both places). It’s difficult to argue with the additional space, however the Sidewinder is 7 ounces lighter (with the same 650-fill fill down and 30-D outer shell). Like the Nemo it comes with an individual pillow pocket that keeps your camping pillows (or down jacket stuffed with down) in place all night. With plenty of features that are geared towards comfort, some sleepers might want to test the two bags prior to purchasing however the Sidewinder is certainly a fantastic option for side sleepers and is priced at only $300.
