Factors to Consider Before Purchasing

Weight

A lightweight sleeping bag is the best for intending or established hikers. The sleeping bag you want to purchase must not be heavy. A heavy bag slows you down on your travels. The weight is crucial because the bag will easy to carry on your adventures if it is lightweight but difficult if the sleeping bag is heavy. The loads you will carry are heavy enough so the bag must be very light in weight.

Temperature Ratings

Temperature ratings give you some general ideas about gear performance and are essential for comparing different sleeping bags. However, there are so many things that influence how warm you feel when sleeping: how much you have eaten, hydration, humidity, fatigue, dampness, and wind.

Think about your camping location; will it be exposed or sheltered? Will altitude be a factor to consider (approximately, for a thousand meters elevation, you will experience a 10-degree drop in temperatures)? Additionally, think about the season you will be spending your night outside.

Sleeping Bag Temperature Rating

The temperature ratings provided by product manufacturers are often based on standard lab tests, and many situations are realistic for most people. If you are an individual, who tends to sleep cold, choosing a warmer bag would be an ideal choice. You can also use a sleeping pad that has a higher thermal rating.

Insulation

Insulation is a factor that affects the warmth of a bag, but other aspects such as the shape, how it’s sewn, and the features included creating an enormous impact on how warm a bag feels.

Synthetics

The plastic thread, either short pieces or continuous long filaments, fills these bags. Many sleeping bags have a mix of thick and thin pieces, as smaller threads, plug empty spaces and efficiently capture warm air, while the strands that are thicker offer loft and durability.

Down

Downs are made up of various plumes –tiny pods of feathery filaments which line the underside of the waterfowl feathers. Down is harvested from geese and ducks prepared for sale. The down fill also contains feather fibers and some feathers. The quality of a down does not rely on the type of bird but rather its environment. Birds usually respond to cold situations by developing warmer and fluffier down.

Gray or white down offer the same performance, but the white one is more expensive since it can be utilized with colored of translucent materials without showing. Fill power is an excellent indicator of quality.

It is expressed as the total number of cubic inches displaced by an ounce of down. A higher fill power offers more warmth for the same weight compared to a lower one.

  • 750-850 is excellent
  • 600-700 is good
  • 500-550 is ok

Liners

The liner of a bag provides a great way for you to sleep more comfortably. The liners may add some degree of warmth, but most of them are designed to wick liquid and keep your bag clean. Therefore, liners require washing less often.

The vapor barrier liners are used in temperatures that are below freezing. They move condensation point outward to avoid the accumulation of moisture inside the bag and were especially helpful for long journeys and extended trips where drying them out might be difficult.

Loft and Volume

Loft and volume are industry-standard measurements which make it possible for you to compare various sleeping bags. Loft measures how puffy a sleeping bag is. If two bags come with the same kind of fill, shape, and features, the one with a greater loft would be warmer.

Volume measures how small a bag is after it has been stuffed into a cylinder using a given amount of pressure. You may be in a position to pack the bag smaller than the stated standard, but if this happens, make sure you shake it out thoroughly and give it some time to recover its loft before going to sleep.

    When I am on my long backpacking adventures, I am very mindful of the weight of the gear I choose to take with me. I want comfort but without unnecessary weight. That is why the Hyke & Byke Ultralight Mummy Down Sleeping Bag is such a perfect fit for me. It is very lightweight, compact and quite easy to carry with me. Its compression sack makes it really easy to fit in my backpack.

    • John C. Porter

      That’s correct, who would want to carry a very comfortable sleeping bag but weighs a ton? Not with the Hike & Byke. It is the lightest and most compressible gear in the market. It’s really perfect for camping and very easy on the pocket.

  • William Anderson

    Sleeping in comfort while camping does not mean breaking your back with heavy gear. I am so happy that I bought the Ledge Sports Ultra Compact Sleeping Bag. It is a permanent member of my backpacking gear. For such a comfortable bag, it is so light.

  • John C. Porter

    That’s correct, William – that sleeping back is so light and easy to carry on your pack. After hours of trekking before you reach camp, it’s gentler on the back and won’t make ache all over. It’s so comfortable that you can sleep soundly after all that walking. 🙂
