The 3 Best Wearable Sleeping Bags of 2025

Top pick

My friends and I have clocked hundreds of hours of toasty front-porch and backyard socialization since 2020, wearing the tester models in temperatures ranging from a high of 65 degrees Fahrenheit to a low of 42 degrees. After all this, I am in love with the Poler Reversible Napsack.

This mummy-shaped bag, which has been around since 2014, comes complete with a hood, zippers in the arm areas, and an open bottom with a drawstring. The current model of the Napsack is made of rip-stop nylon and has included recycled synthetic material since 2021.

The Napsack is cut fairly narrow. It comes in four sizes, S to XL. The sizing is based on height, though width is also a consideration. If you plan to use it as a sleeping bag, the manufacturer recommends sizing up to ensure you have enough room at the bottom, which cinches shut via drawstring. I’m 5 feet 5 inches and am wearing a M in the photo.

To get the best fit, you’ll want to double the width measurement on the bag to get the girth, and compare that to your own measurements to ensure the bag won’t be too snug in any one spot. My 6-foot-4-inch friend can fit into the M width-wise, and the bottom stops at his ankles. The company recommends sizing up if you’re in doubt.

• S: 23 inches (W) by 63 inches (L); fits people up to 5 feet
• M: 26 inches (W) by 67 inches (L); fits people up to 5 feet 8 inches
• L: 31 inches (W) by 85 inches (L); fits people up to 6 feet 3 inches
• XL: 37 inches (W) by 91 inches (L); fits people up to 6 feet 8 inches

The Reversible Napsacks are rated to 50 °F, based on real-world, non-lab testing. I found this to be true in my testing, and I was able to add or remove layers to maintain warmth in a wide range of temperatures.

All of this means you can wear it indoors without feeling too hot (like, ahem, when your partner refuses to turn on the heat in October out of principle). The Reversible Napsack (stuffed with Poler’s proprietary, synthetic Thermastuff, which is made from 180-gram polyfill) did a great job of keeping my core warm. Jeans, a long-sleeve base layer, and a sweatshirt under the Reversible Napsack were usually enough to keep me toasty during 50ish-degree weather. As temps have dropped further, the Napsack is slim-cut enough to layer under a jacket for even more protection.

One NYC-based Wirecutter staff member spends her workdays outside with her laptop next to her fire pit, using the Reversible Napsack in temps as low as 30 °F for warmth and to protect her clothes underneath from smelling like smoke. “If I’m sitting for a while, I like to put down a sheepskin to cushion and warm my tush,” she says (which is, quite literally, a hot tip). Note that if you plan to use any of these wearable sleeping bags near a fire pit, it’s important to maintain a safe distance and not tend to the fire yourself. These bags are not fire retardant.

The armholes are curved, making the Napsack comfortable to wear, and the stitching is reinforced. The main zipper has a flap to reduce the chance of the material snagging in the zipper’s teeth. Two front snap pockets at the waist and a snap breast pocket easily holds my phone and small items, like hair ties and tissues. The hood sits relatively close to my head, keeping it warm. And the drawstring makes it a cinch (oh, yes I did) to tighten the hood around my face on breezy days, when I need a little extra protection.

In late 2021, Poler introduced the Shaggy Napsack, which is currently out of stock, but a company rep told us it may be reintroduced in 2026. This is a polyester-fleece-lined version of the Napsack that the company real-world rates to 40 °F. Since the interior is lined, this bag is not reversible, but that probably doesn’t matter to most people. The reversibility of the original Poler Reversible Napsack feels more like a party trick than an exciting feature.

The Shaggy Napsack was much warmer and cozier than its original counterpart, but it’s also approximately a pound heavier and doesn’t stuff down quite as tightly. This isn’t a big deal when hanging out in your backyard, but if you’re camping and need to carry gear, every additional pound matters. In the three years I’ve had it, it’s been my go-to bag during chilly workdays in my attic office. If it returns, this is a good option for people who want that extra warmth and can swing the upcharge and extra weight.
