Big Agnes

Sidewinder Camp 20 | Men's

Colour: Indigo/Grey

Synthetic bag custom-made for side sleepers

People who sleep on their sides tend to have a rough time of it when they go camping. Unlike back or front-sleepers (yeah, apparently the latter do exist), the shape of the slumbering human body doesn’t conform easily to hard, flat ground. Aching shoulders and hips are a common result. And that’s before we get on to the problem with standard sleeping bags, which tend to end up twisted around you like a boa constrictor, with the zip digging in uncomfortably somewhere underneath you. If that sounds familiar, the Sidewinder Camp 20 is going to be a genuine game-changer. Constructed with a plush relaxed cocoon style pattern, it drapes around the body to mimic your quilt at home with two-layer, blanket style quilting. It’s also ergonomically contoured for side sleepers, even if you tend to roll over in the night, thanks to a specially designed hood and footbox

  • Big Agnes is a small, independent US outdoor brand out of Steamboat Springs, Colorado – a small ski-town that we’ve never visited but which we like to imagine is full of mountain-loving, trail-hiking outdoorsy types. That would make sense, since the company makes some of the best ultralight backpacking gear around, including the award-winning Copper Spur, Tiger Wall and Fly Creek tents. It is kit that has clearly been designed by a gang of folks who love sleeping in the dirt just as much as we do here at WildBounds.

    Oh, and if you’re still wondering where the heck that name Big Agnes comes from, we did try to find out. Depending on who you talk to, it’s either an affectionate tribute to a legendary truck drivin’ mountain mama, or a 12,000 foot peak in the Mount Zirkel Wilderness. We kinda like the first one better.

The best sleeping bag I've ever used! It kept me warm in Denali..
