Kelty Catena 30 Sleeping Bag

Great value for any weather

Source: rei.com

Best for: 

  • Newbie campers
  • Warm days with cooler nights

What people like: 

  • Affordable
  • High quality
  • Rectangular and can be used as a blanket
  • Breathable but warm for cooler nights
  • Comfortable material

What people don’t like: 

  • Loud fabric
  • Not compact

The Kelty Catena synthetic sleeping bag is rated at 30 degrees and is perfect for casual camping and car camping. Since it’s rated at 30 degrees, it’ll keep you warm on cooler summer nights. 

Then on warm nights, you can unzip the sleeping bag all the way and just use it as a blanket instead. The sleeping bag also has the ability to connect to another Kelty Catena to make a mega-sleeping bag!! YES!

It’s super affordable for such a high-quality bag, and as long as you’re not concerned about weight or size, this might be the perfect summer sleeping bag.

Big Agnes Sidewinder SL 35 Sleeping Bag

Best for:

  • Side sleepers

What people like: 

  • Anti-snag zippers
  • Very comfortable for side sleepers
  • Works for warm to cooler weather
  • Very snug inside

What people don’t like: 

  • Can be too warm for hot nights
  • Heavier than most–not made for backpacking


If you’re a side sleeper, you might know that most sleeping bags just aren’t made for you. You might have found yourself waking up in the middle of the night with the zipper digging into your face or side. But luckily Big Agnes made the Sidewinder SL 35 bag for all of us side sleepers out there. 

The Sidewinder bag is a partial mummy bag with a hood for your head, so it’s appropriate for cooler nights. However, since it is rated at 35 degrees, it may not be great for warmer temps. 

As far as space goes, it keeps you snug but still has plenty of space inside for side sleepers who like to sprawl out a bit.

The best part about this bag is the weight. It’s just under a pound and packs down incredibly small. So for summer backpacking, I highly recommend this bag.

Sea to Summit COOLMAX Mummy Liner

Moisture-wicking for hot and humid summer nights

Source: rei.com

Best for: 

  • Very warm nights (on its own)

      Or

  • As a sweat-wicking liner in your sleeping bag

What people like: 

  • Keeps you cool at night
  • Lightweight
  • Very compact
  • Very comfortable material
  • Works well alone or inside another sleeping bag

What people don’t like:

  • Doesn’t have a zipper

Using a liner on its own, like this one from Sea to Summit is probably your best option if you’re a really warm sleeper and/or you’re going to be sleeping in very hot and humid weather. Otherwise, you can also use a liner inside another lightweight sleeping bag to wick sweat and keep you cooler.

The COOLMAX is lightweight, super compact, and very comfortable. It’s designed to wick sweat away from your body so you can sleep well even in really hot weather. Keep in mind though, this liner doesn’t have a zipper at all, so it’s not like a regular sleeping bag.

Kelty Rambler 50 Degree Sleeping Bag

Great quality for warm nights

Best for: 

  • Summer hammock camping

What people like: 

  • Foot vent for warmer nights
  • Great quality
  • Packs small
  • No snag zippers

What people don’t like:

  • Not warm enough for cooler nights

The Kelty Rambler 50 is an excellent summer sleeping bag. Many people use it for summer hammock camping, since it’s not as restricting as a mummy bag. However it’ll still keep your feet warm when you don’t have that extra warmth from a sleeping pad under you.

Keep in mind, it’s rated at 50 degrees, so on cooler nights you might need some extra warmth from a liner or some warm clothes.

How to Choose a Sleeping Bag for Warm Weather

Here’s everything you need to look out for when shopping for summer sleeping bags…

Temperature Rating

Every sleeping bag manufacturer will give their sleeping bags a rating. The rating represents the coldest temperature the sleeping bag can be used in and still keep you comfortable. For summer sleeping bags, look for those with a rating between 30 and 60 degrees.

A sleeping bag with a rating of 30 degrees might be more appropriate when the weather is variable, or in places with warmer days but cool nights. A sleeping bag with a rating of 50 to 60 will be best if you’re staying in hot, humid weather.

Type of Insulation

There are two main types of insulation in sleeping bags: down and synthetic. Down means the bag is insulated with goose down feathers. Down insulation is warmer and more lightweight, but way more expensive. Synthetic sleeping bags are not as insulating and a little heavier, but they’re less expensive. 

Down is very insulating, but can also help keep you cool on warm nights. Overall, if you really need a lightweight bag and you’re willing to splurge, then a down-insulated bag is a good choice. If you’re a casual camper and don’t need anything fancy, synthetic insulation will work just fine for you.

Insulation is way more important for cold weather sleeping bags, so for warmer weather, choosing synthetic will not have many drawbacks as long as you don’t need an ultra-lightweight bag.

The Shape – Rectangular, Semi-Rectangular, or Mummy?

There are three general shapes of sleeping bags you’ll find when shopping: rectangular, semi-rectangular, and mummy. Here’s an example of each (in that order):

different shapes of camping sleeping bag

Rectangular sleeping bags, like the Kelty Catena 30 are overall a rectangular shape and are not shaped to fit your feet or head snugly. Most rectangular bags unzip all the way and can be used as a blanket. But because they aren’t as snug, they won’t be as warm compared to other bags.

Semi-rectangular bags, like the Kelty Rambler 50 are rectangular in the head area but have a smaller compartment to keep your feet warm. These are great bags if you tend to get cold feet at night, or if you don’t like the ultra-compressing feel of a full mummy bag.

Mummy sleeping bags are usually the warmest and are designed to fit snugly to your whole body. Like the Therm-a-Rest Space Cowboy, they have a “hood” for your head and a very compact foot compartment.

Some people can feel claustrophobic in a mummy sleeping bag and for some, that snugness helps them sleep. This choice really comes down to personal preference and how you sleep most comfortably. Overall though, if you want a warmer bag, go for a mummy. And if you want a bag that you won’t get sweaty in and that can be used as a blanket, go for a rectangular bag.

Zippers

Believe it or not, zippers are one of the most crucial parts of a sleeping bag. Picking a sleeping bag that has anti-snag zippers can help get out of some frustrating packing and unpacking situations.

Many bags also come with vent zippers, zippers on both sides, and full wrap-around zippers so you can open the bag up into a blanket. All of this is up to personal preference, but for summer sleeping bags…vents and wrap-around zippers are great things to look for because both will help keep you cool if it gets warm at night.

Liners

Sleeping bag liners can either be added to the inside of your summer sleeping bag, or you can use them on their own in very hot weather. If you don’t like the feel of the inside of your sleeping bag or you don’t want to have to wash your sleeping bag often, you can comfortably add a liner that can help wick away sweat and won’t add a ton of extra warmth.

Using a sleeping bag liner alone, like the Sea to Summit COOLMAX, is also a great option if you’re going somewhere where it’ll be really warm and humid at night. (Or if you’re just a very warm sleeper.)

The Price

Summer sleeping bags can range in price from about $20 to around $300. So whatever your budget is, there’s one out there for you. Unlike with winter bags, you don’t have to spend a lot of money to make sure you stay comfortable at night. 

Spending more money on summer sleeping bags will mostly contribute towards a lower weight and smaller packing size. If that’s not a priority for you, a budget bag may be just as comfortable as a pricy one.

Packed Size

Packing size will be a priority for you if you’re backpacking, or if you don’t have a lot of room in your car or camper. Luckily, summer sleeping bags are super lightweight and don’t have a ton of insulation so they can get pretty small.

The smallest of summer sleeping bags can fit in the palm of your hand when fully compressed! But keep in mind that the smallest of sleeping bags likely won’t have enough insulation to keep you warm on cooler summer nights.

Warm Weather Sleeping Bags FAQs

Do you need a sleeping bag in warmer weather?

Technically, no you don’t need a sleeping bag in warmer weather. But it’s all about your personal comfort. If you’re someone who needs to be covered in a blanket to sleep, then a lightweight sleeping bag will help you feel more comfortable, even in very warm weather.

What is the best type of sleeping bag for warm weather?

The best warm weather sleeping bag is any bag rated at or above 30 degrees. If you sleep warm, then the best sleeping bag for you might be a large rectangular sleeping bag that unzips all the way around so you can use it as a blanket or pull it down if you get too warm.

What is the coolest sleeping bag?

The coolest sleeping bag is likely a sleeping bag liner, like the Sea to Summit COOLMAX. It’s very lightweight and designed to wick sweat away from your body for the hottest of nights.

Can you use a zero-degree sleeping bag in summer?

You can use a zero-degree sleeping bag in the summertime, but it might not be very comfortable. Zero degree sleeping bags are designed to really insulate your body, so you might end up sweaty and uncomfortable when using one in the summertime. Instead, try to get a warm weather sleeping bag that’s rated at 30 degrees and up.

Conclusion

Are you gonna splurge for the super high quality, lightweight Sea to Summit Flame? Or maybe you’re the opposite, and you just need a simple bag to keep you cool on a budget, like Ohuhu’s 3 season bag. 

Whichever you choose, remember that picking a summer sleeping bag is all about your personal comfort. And whatever your needs are for a comfy summer bag, there’s something on this list for you.
