great summer sleeping bag

I've put it through the wringer

Dries quickly if you leave your window open, keeps its fluff nicely, roomy and recommended for car camping. It's NOT warm to 30 degrees, at least for this princess, but add a liner and it's fine. Has held up really well and somehow doesn't seem to stain!

Awesome! Thanks Laura for the good insight and a heads up with the comfort rating on this bag.

Light Weight, and Warm

I've used it several times

I really enjoy this bag. It packs up nice, and is very light weight for how warm it is. I would recommend to anyone that is looking for a great sleeping bag that will keep you warm and last a very long time!

Sleeping Bag Success

I've used it several times

This sleeping bag is roomy and comfortable. It is perfect for fall, spring, and summer nights-on the chillier nights it keeps heat and on warmer nights is breathable.

For car camping rectangle is king!

I've put it through the wringer

The rectangle gives me more room to sleep in a normal position. When I move around this sleeping bag stays in more natural position. I love it! Rectangle for life!


Kelty Callisto 30 Overview


Does this bag come with a decent stuff sack?


can this sleeping bag be zipped with another sleeping bag to make it a double?

Hey Erin, Great Question! This sleeping bag can be zipped with another to make it a double sleeping bag, but you'll need to make sure your other sleeping bag is compatible with this one. Do you already have another sleeping bag that you are looking to attach to this one? Sleeping bags don’t have to be exact matches to get together, but they do have to be compatible in the following areas: the zippers must have the same sized teeth, the zippers must be the same length, and one bag must have a right-facing zipper while the other has a left-facing zipper. This sleeping bag only comes in a right zipper, so you will need to have a left zipper bag in order to connect them successfully. It is 72 in long, and the zipper is full length. You will want to make sure your other sleeping bag meets all these components. Reach out to me at for more advice on sleeping bags and other camping gear! Happy to help with anything you may need!
