Comfort and Design
Synthetic sleeping bags are designed by a variety of companies that each make their own fill. There are also different types of sleeping bags that each reap their own benefits, style, and comfort. Most commonly, though, are two kinds of fill:
- Short staple fibers: similar to 3D plume structures and are easy to compress. However, its longevity is not as good. This fill tends to wear down after many uses and re-stuffings.
- Continuous filaments: weave at a longer length with many different diameters so that it is durable and better insulated, though it does make it less compressible. The shorter compressibility just means it does not pack as well, but this is not an issue that is too hard to get around.
Synthetic sleeping bags vary from down sleeping bags’ lofting and updates. Synthetic fill has not yet matched their longevity and compressibility. This is simply because synthetic fibers cannot loft as well as high-quality down.
However, this should not stray you from synthetic sleeping bags. With the proper information, you can start to understand why so many are now buying them instead of down bags:
Buyers are attracted to synthetic fabric because of its ability to maintain warmth even when it is wet. Yes, it makes more sense to keep sleeping bags dry but life happens, so synthetic insulation is ideal for keeping the owner comfortable even when they are wet, or the fabric is wet. Camping trips in humid weather can happen more often now that synthetic fabric is better for it. Also, unexpected inclement weather will not put such a damper on your trip because you know that your sleeping bag is safe.
Synthetic insulation dries faster, insulates even when wet, is non-allergenic, and less expensive. This fabric is kinder to those with different allergies that down contains. It is also better for younger campers as it is easier to care for and has better warmth insulation.
Synthetic fabric does not compress as well as down fabric. It has a lower weight-to-warmth ratio, meaning it will be heavier than down. Sleeping bags are typically heavier if they keep you warmer because of how much fill is needed to retain warmth. Synthetic fabric and fill retains warmth better because it weighs a little more than down.
Sleeping Bag Selection
With all this information, you may now be wondering what the best choice is. Imagine: it is the end of a long camping day, out in the sun or even the cold. One is probably wishing they could crawl into their soft, warm bed; but they’re outside! Synthetic sleeping bags are the closest thing to that.
When buying any sleeping bag, you should look at a few things:
Price: The sleeping bag is always the most expensive out of all camping materials, but synthetic sleeping bags are more cost-efficient. This is why most people weigh the costs the most when choosing a sleeping bag.
Weight: The sleeping bag is also the heaviest, and will account for most of the weight in your bag.
Warmth: You may not know this, but it is your body that creates the warmth and not the sleeping bag—the bag just insulates it and traps it around you. The more insulation, the better. Synthetic sleeping bags pack more insulation with less weight.
Temperature: All sleeping bags come with a temperature rating that will help you choose the best bag for what you plan to do. The best bag is between 15 degrees F and 35 degrees F. The best thing is to consider that, and the temperature that you plan to be active in.
Bag length and width: The manufacturer will disclose the correct length and you should match it to your height. The longer is usually the better. If a bag is too slim, you should choose a different model with a greater width. More width can be beneficial especially when there are drafts at night and heavy winds. If it is very cold and you have to sleep in thicker clothes, it is more comfortable as well.
If you are sharing a tent with many people, it is best if the bags do not take up too much space. This is why compressibility is important as well as the width and length.
Storing Your Bag
It is not advised to keep any sleeping bag compressed. You should always remove its stuff sack and keep it in a dry location. It is also good to keep it where you have room to spread it out and hang it up. If you do store a bag while compressed, even synthetic, it damages the insulation.
Sleeping bags cost more than any other outdoor equipment and that is because it is expected to last longer. Help your bag last as long as it can by following simple care rules. If your sleeping bag is machine washable, make sure the setting does not have an agitator, as that may tear the fabric.
Before packing your bag up, it needs to air dry for at least 24 hours. You should also avoid storing your bag for long periods of time. The tight compression on the insulation can cause it to lose its loft and warmth trapping capabilities.
After you wash your sleeping bag, which should not be done very often, you can dry them in the dryer on a low setting. Synthetic fabric is also easier to care for in this way as it does not have as many restrictions as down. To help restore the insulation’s loft, put a clean tennis ball or two into the dryer halfway through the cycle. It is a little noisy, but it is effective so it is worth it.
Now that you have all the information on synthetic sleeping bags, where to find them, how to find them, and how to choose the right one, you can plan your next camping or outdoor trip without worrying about more expensive sleeping arrangements.
