Best Sleeping Bags
Preset Algorithm Ranking

This list is sleeping bags only, the hooded, fully enclosed shelters, with quilts and bivies filtered out. If you want the draft-sealing warmth of a real bag rather than the ultralight openness of a quilt, this is the ranking, scored on standardized warmth, warmth-to-weight, packed size, and value.

The full picture

A sleeping bag wraps you completely: a hood, a draft collar on warmer models, insulation all the way around, and a full or partial zip. That enclosure is what a quilt gives up for weight, and it is why cold sleepers, exposed sites, and anyone who moves around at night tend to prefer a bag. The trade is a little more weight for the same warmth, since a bag insulates underneath you where a quilt lets the pad do the work.

Because every bag here is fully enclosed, the ranking comes down to how efficiently each turns insulation into warmth you can carry. Warmth-to-weight leads, backed by packed size and, through the temperature model, the honesty of the rating: a lab EN/ISO comfort figure counts for more than an optimistic maker number, and the Rating column shows which is which. Down bags dominate warmth-to-weight, while synthetic bags earn their place on value and wet-weather reliability.

Fit and shape matter more in a bag than the spec sheet shows. A tight mummy is warmer and lighter but less roomy, while a semi-rectangular or rectangular bag trades some warmth for space to move. We rank on the published numbers (warmth, weight, packed size, price) and show the shape on each product page, so you can weigh how snug you want to sleep against how warm and light the bag is.

Common questions

Should I buy a sleeping bag or a quilt?

A bag fully encloses you with a hood and back insulation, which seals drafts and suits cold sleepers, exposed cowboy camping, and restless sleepers. A quilt is lighter and packs smaller but relies on your pad and some technique to stay warm. If you sleep cold or want fuss-free warmth, a bag is the safer pick; if you chase the lowest weight, look at the quilts list.

What shape of sleeping bag is best?

It is a trade-off. A mummy is the warmest and lightest for its rating because it minimizes dead air, but it is snug. Semi-rectangular bags add room to move for a small warmth and weight penalty, and rectangular bags are roomiest but heaviest, which suits car camping more than backpacking. Match the shape to whether you value warmth-to-weight or interior room.

Down or synthetic for a sleeping bag?

Down gives the best warmth-to-weight and packs smallest, so it leads this ranking, but it costs more and needs to stay dry. Synthetic keeps more of its warmth when damp and costs less, at the price of more weight and bulk. The Fill column and the algorithm panel let you re-rank around whichever matters more for your trips.

How are sleeping bags ranked here?

GearScore filters to fully enclosed bags, then blends published specs: a warmth threshold you set, warmth-to-weight, packed size, and value, with lab-tested ratings weighted over optimistic maker numbers. Nothing is opinion or sponsorship, unpublished specs show "n/s" and never score as zero, and you can re-weight any factor.

Bang for Your Buck

Dollars per point of GearScore. The lower the number, the more quality you get for your money. Each bar carries both metrics at once: a solid bar for the highlighted one over a faded ghost of the other. Sorted to the best value first, and always scored by the algorithm you've set above.
