Best Rectangle Sleeping Bags – My Top Picks!


Rectangle sleeping bags are perfect for summer camp, backyard adventures and car camping along the Oregon coast.  Rectangle sleeping bags are roomier than other bag shapes, allowing you to get comfortable and sleep on your side, back or stomach without feeling claustrophobic. For this blog, I’m going to be taking a closer look at the best rectangle sleeping bags on the market today. I hope you find this information helpful and that it aids in your preparation for your next camping trip.

The best rectangle sleeping bags will vary depending on where you are camping, the weather conditions and whether or not you want the added option of zipping two sleeping bags together. Unlike mummy or semi-rectangle shaped sleeping bags, rectangle shaped bags allow you the option to add another bag together for extra warmth on a cold night. Rectangle bags are best for summer and fall camping. However, if you’re heading into the backcountry, you will want a mummy shaped bag to keep warm air close to your body.

Rectangle Sleeping Bags 101

Rectangle sleeping bags are an excellent choice if you don’t like to feel restricted in your sleeping bag. Rectangle bags are excellent for backyard campouts, car camping and short hikes into a lake or river. As I mentioned earlier, rectangle shaped bags most often rated to keep you warm when the temperature ranges from 15 degrees to 40 degrees and above. With this temperature range, you can safely and comfortably camp during the summer months, fall and even late spring- depending on where you live.

Rectangle sleeping bags tend to be the most budget-friendly sleeping bag-however, there are a few brands in the higher price range.  In general, rectangle sleeping bags are basic and don’t have a whole lot of extra features, which means you get a break on the price.  In fact, you can easily find a down rectangle sleeping bag for under $100.  If you’re on a budget and don’t want to sacrifice warmth, comfort or quality, a rectangle sleeping bag is a great choice for you.

If you add a sleeping bag liner to the bag, you might get away with making it work when the temperature dips below freezing.  However, don’t attempt to bring a rectangle bag with you if you’re planning an expedition to Mt. Rainier or other extreme alpine adventure. You will freeze.  Stick to summer camping and you’ll be just fine.  Let’s take a closer look at the best rectangle sleeping bags on the market today. Ready? Let’s go!
