Thinking about getting a lightweight summer sleeping bag? This article highlights the key points you should know. Lightweight sleeping bags pack down to a small size, helping you cut down on the volume your bag takes up. Since extra weight can make a hike or trek more physically demanding, they are good for people who haven't been backpacking or camping before and aren't used to carrying a big load. Easy to carry, they can be carried with you no matter the trail since they can effortlessly get packed into any size bag. However, they are typically not as well-insulated, so they aren't designed for sleeping out in very low temperatures.

Summer sleeping bags have a breathable design, preventing condensation from building up on the inside. They are more affordable, so if you don't plan on using your sleeping bag during colder months, you can save money and buy one that is good for warmer weather. These sleeping bags have a lighter design, with plenty of extra room to bring other gear. They are made with multiple ventilation options, so they have a pretty wide temperature comfort range.
