Outdoor camping is one of the best ways to travel if you want unforgettable experiences right in the heart of nature. From stargazing to tasty barbecues and frightening stories in front of a bonfire, camping comes with plenty of perks for nature lovers.  However, one of the most important things to take into consideration is to always be prepared for the worse and come with proper equipment, including a good season sleeping bag. Searching for the perfect item could prove a difficult task, especially since there are plenty of options available on the market.  After having read plenty of online reviews from happy customers all over the world, we have concluded that one of the best 3-season sleeping bags on the market is the Sportneer +20F Ultralight Mummy because it comes with stuffed 100% silk cotton, it provides a cosy and tight fit throughout the night and comes for an affordable price. If the Sportneer +20F Ultralight Mummy is not available for purchase, our second best suggestion in terms of quality and comfort is the OutdoorsmanLab Sleeping Bag.


If you are looking for a new 3-season sleeping bag but you’re not sure which one is the perfect option for you, our comprehensive buying guide will give you all necessary information and tips to make sure you purchased the right item. Here is what we think you should take into consideration.


The size of the sleeping bag

Finding the right size and fit for your sleeping bag is crucial if you want to have a good night sleep and stay warm even during the cold seasons. Depending on your own body dimensions, we suggest measuring the sleeping bag carefully before purchasing it.

Although most of the sleeping bags come in standard one or double sizes, some of them are larger or longer than others and, so, are suitable for shorter or taller people. Most sleeping bags will comfortably accommodate a person up to 6.2 feet tall and 200 pounds but, again, you should first look for the instructions.


The fit of the sleeping bag

As for the fit, you can choose between different styles, again depending on your personal wishes and sleeping style. The most popular sleeping bag styles are the mummy ones and the regular ones.

Just like the name suggests it, the mummy style will smoothly wrap your body up in a few thick layers of comfy and breathable fabrics so you won’t require an extra blanket. The main advantage of these is that they occupy less space and will keep your body warm and fitted all night long. On the other hand, if you are feeling a little bit claustrophobic or you have the tendency of moving around a lot while sleeping, you will certainly have to pass the mummy fit.

The regular sleeping bag is suitable for one or two persons and features enough room to move your legs and feet during the night. However, if you are usually cold, you might want to add up an extra blanket or a pillow to keep you warm, especially if the sleeping bag is a bit large for your own body fit.


Single or double?

If you plan on traveling with your significant other and want to feel the warmth of your partner’s body even during your camping nights, there are plenty of double sleeping bags that you can acquire online.

Just make sure to purchase one that will fit both of you and will still leave plenty of room to sleep well without feeling too crowded.
