Mummy bags vs. Rectangular Sleeping Bags. Which one is better?
Above, we have mentioned and described the best lightweight sleeping bag for backpacking, and most of them are mummy bags. Mummy bags are excellent at trapping heat, while on the other hand, rectangular bags are great for tossing and rolling and moving freely while sleeping. So, which one is better? Let’s consider some points below.
- Comfort- When you consider comfort as the most important aspect of your sleeping bag, you must know that mummy bags offer a little more space than rectangular sleeping bags. Mummy bags constrict your movement. Rectangular sleeping bags are excellent for large people and even for people who love to roll and toss while sleeping. Hence, if you are a large person and want quite a room while sleeping, there’s nothing better than a rectangular sleeping bag. So, a rectangular sleeping bag offers more room for movement than a mummy sleeping bag.
- Warmth- If you backpack to cold places, this point is of utmost importance. A mummy sleeping bag is more efficient in colder temperatures. The body of the sleeper is entirely closed, and only the face and mouth are out. The form-fitting and constricted shape of the mummy bag enable efficient insulation. It restricts the amount of air inside the body and does not let cold air in. Hence, your body generates less heat to maintain the bag’s temperature.
On the other hand, rectangular sleeping bags are ideal for above freezing temperatures. Rectangular bags have a lot of space where cold air can enter and give you chills. But, rectangular sleeping bags are much better in summers. You can open the zipper for extra ventilation. Also, by opening the zipper, you can use the sleeping bag as a quilt as well.
- Backpacking- When you are backpacking, mummy sleeping bags are your best choice. They are light-weighted and easy to carry. You can easily compress them, and they are compact as well. When you are trekking and hiking, mummy bags are relatively easy to carry. At the same time, rectangular sleeping bags can be a bit bulky. There are lightweight rectangular sleeping bags that you can use for medium to short backpacking trips. But, if you are out of the country or to the hills for backpacking, you must go for mummy sleeping bags.
- Price- Sleeping bag’s worth is significant when you are on a budget. A sleeping bag is an essential gear in your backpacking, and you cannot leave without it. But, it can be the costliest as well. So, when you are on a budget, you must make your choices wisely. High-quality mummy bags can be pricier than a lot of high-quality rectangular sleeping bags. Simultaneously, low-priced mummy sleeping bags are the same price as the rectangular bags in the same price frame. If you are on a budget, you can go for a rectangular sleeping bag or a lower-end mummy sleeping bag. But, if you bucks to spend and quality is of top priority, then go for a mummy sleeping bag.
We can never conclude whether mummy sleeping bags are better or rectangular sleeping bags. So, it is on you, the decision of choosing the right sleeping bag. You must select a sleeping bag that fits your list of considerations.
So, we have featured the best lightweight sleeping bag for backpacking in this article. These sleeping bags are the lightest and also offer great value for money. So, if you are a regular backpacker or hiker, then choose the best lightweight sleeping bag and head to your next trip.
