A simple tip for sleeping comfortably when camping is to invest in a good sleeping bag. But if you're a side sleeper who's ever tossed and tangled inside of one, you're not alone. However, the Big Agnes Sidewinder SL 20 is a traditional mummy-style bag designed specifically to better fit side sleepers. At the time of writing, it's on sale from Agnes at just over $212, but campers can also check their local Costco to score it at a deal.

Seasoned campers say the Sidewinder is a game-changer for side sleepers. On Reddit's r/CampingandHiking, u/clegshartley said, "I began using a BA Sidewinder SL 20 this year, and it's the best sleep I've ever gotten on the trail." Adding that they picked it up mainly because it was a good deal, they've now realized "having the face opening and the zipper on the same side of the bag makes for a much more comfortable night of sleep." Meanwhile, u/satans_fist seconded, saying, "Big Agnes Sidewinder is a great bag."

Big Agnes built the bag with side sleepers in mind, using strategically placed down and synthetic fill around pressure points like hips and shoulders. Plus, the zipper is placed across the chest, meaning sleepers won't end up rolling over on top of it. It also comes in regular size and long size to accommodate campers taller than 6-feet. Between the technical fit and real-world praise, side sleepers say the Agnes Sidewinder SL 20 is a solid, affordable choice for camping with more comfort.

Beyond the fit, the Sidewinder offers a great value — especially factoring in Costco's discount prices and generous return policy. At just over 2 pounds, it's not an ultra-light bag ideal for long backpacking journeys. But it's not overly bulky or heavy, helping you pack lighter on your next camping trip. Probably one of its most notable features is that it's "patterned to move with you as you roll from one side to the other" (Big Agnes).

Small design details are also meant to make nighttime less fussy, including a footbox shaped to mimic your foot's position when lying on your side, an anti-snag center zipper, and a pocket for your phone. To upgrade your camping gear for a sounder sleep in nature, consider pairing the Agnes Sidewinder with an insulated sleeping pad, like this one on Amazon from Gear Doctors, especially in colder environments. The Sidewinder also repels water and has a built-in pillow pocket to hold your pillow in place as you move around.

Still, no gear is perfect. Reviewers at Better Trail note that those with larger feet may find the footbox snug, and despite having an anti-snag zipper, it can get caught occasionally. But even with those caveats, the consensus is that the Sidewinder is thoughtfully designed and a good bag for the money. So if side-sleeping solitude is part of your camping style, seasoned campers say the Sidewinder SL 20 is a solid option, whether you're into "cowboy camping" under the stars or snuggling up in a solo or shared tent.
