#4: Sea to Summit Trek Down 15
Our top pick for spacious, adaptable comfort.
The Sea to Summit Trek Down is a semi-rectangular sleeping bag that blends the warmth of a mummy bag with the roominess of a traditional design. Its 650+ fill power RDS-certified down delivers reliable insulation, while the Free-Flow zipper system allows for customizable ventilation, making it perfect for campers who want to adjust their warmth on the fly. We love the thoughtful extras, like the dual storage sacks and the ability to zip two bags together for couples.
Summary
Best For: Car camping, overlanding and casual backpacking
Pros: Roomy yet warm, versatile zipper system, ethically sourced materials
Cons: Not the most compact, can feel clammy in humid conditions
Verdict: A top-tier choice for campers who prioritize comfort and flexibility over ultralight packing

#3: Kelty Cosmic Ultra 20F
Top pick for bang-for-your-buck quality.
The Kelty Cosmic Ultra 20F hits the sweet spot between warmth, weight, comfort and affordability. While it's a mummy-style bag, the roomier foot area gives you space to move, the zippers work smoothly and the inner pocket sits right where you need it.
Summary
Best For: Backcountry trips, cold-weather camping
Pros: Cozy, toasty, sheds moisture well, and easier on the wallet than most
Cons: Could use a better compression sack - it takes up more pack space than some competitors
Verdict: A reliable performer that won't break the bank
Featherlight champion.
Tipping the scales at just 1 pound 4 ounces, the Therm-a-Rest Hyperion is unbelievably light for such a well-made sleeping bag. Designed specifically to shed weight for multi-day treks, this does come with some trade-offs. You'll find it's not quite as warm as bulkier options, has a snug fit, features only a partial zipper and carries a premium price, but if compact packing is your top priority, nothing beats this.
Summary
Best For: Extended backpacking adventures
Pros: Remarkably lightweight, built to last
Cons: Snug interior, less insulation than others
Verdict: The ultimate sleeping bag for serious distance hikers
Where to get it:
Our top pick for lightweight comfort.
The North Face Blue Kazoo is a snug mummy-style sleeping bag that hits the sweet spot between warmth and weight. It shrugs off moisture well and uses soft, breathable materials that keep heat evenly spread. We're especially impressed with the smart details like the adjustable hood, handy storage pocket and extra neck insulation.
Summary
Best For: Backpacking trips in damp or humid weather
Pros: Cozy yet lightweight, built to last
Cons: Foot area feels a bit cramped
Verdict: An excellent sleeping bag for trail adventures

Sleeping Bag FAQs
What is the number one sleeping bag?
Picking the best sleeping bag comes down to what works for you and your specific requirements. After testing top-rated sleeping bags in the US, we found The North Face Blue Kazoo performs best in cold conditions. Other excellent options come from trusted brands like Sea to Summit, Therm-a-Rest and Kelty.
Is it OK to sleep in a sleeping bag every night?
Sleeping in a bag nightly is usually fine, but doing so regularly might cause discomfort or cleanliness concerns. Remember to air out your sleeping bag frequently and follow the care instructions for washing.
How often should you replace a sleeping bag?
How often you need a replacement depends on how much you use it, how you store it and general wear. Well-made sleeping bags can serve you well for years if cared for properly, but consider upgrading if you notice less warmth or performance over time.
Is it better to sleep with clothes on or off in a sleeping bag?
This comes down to personal comfort and the weather. Adding dry, clean layers can help you stay warmer, but bundling up too much might make you sweat and decrease the bag's effectiveness. While quality sleeping bags spread heat evenly, some models work better with extra clothing layers.
Why am I so cold in my sleeping bag?
Several factors can leave you shivering in your sleeping bag: your bag might not have enough insulation for the weather, it could be low quality, your sleeping pad might not provide enough warmth, you might need extra clothing layers, or your bag’s temperature rating might be too optimistic. Always check that your gear suits the conditions, but know that, sometimes, adding extra insulation helps. For example, the Therm-a-Rest Hyperion 20 is great for lightweight backpacking, but it won’t be the coziest option in freezing temperatures.
Do old sleeping bags lose their warmth?
Yes, sleeping bags can lose insulation as they age. The filling compresses, materials wear out and some poorly made bags leak feathers. Taking good care of your bag and storing it properly can help keep it warmer for longer.
Should you wash a sleeping bag?
Definitely, especially after heavy use or if it gets dirty. Always follow the manufacturer’s cleaning instructions to keep your bag performing well and lasting longer.
