If you are wondering how to restore loft to synthetic sleeping bags, then simply and carefully give a hand wash to this by shaking it too hard and then beating it with a racket.

Or if you have a front-loading washing machine or front-loading dryer then give yourself some time and use those washing and drying machines for restoring your sleeping bags loft. 

To know the step-by-step approach for restoration, keep reading the post because, in this piece, I will explain some practical methods for restoring the loft of a sleeping bag.

The loft should be restored if your sleeping bag is made of synthetic material. So that the next time you go camping, your sleeping bag will keep you warm.

3 Quick Process To Restore the Loft of a Synthetic Sleeping Bag

Here are the three quick processes to lessen your tension about restoring the loft of a Synthetic Sleeping Bag – 

  • Hand wash by shaking and beating
  • By using the Washing machine and
  • The dryer process of Restoration 

1. Hand wash by shaking and beating:

Shaking the bag from the foot end and putting it out on the floor for a day is the most straightforward method for regaining loft. Make sure you don’t shake the bag too forcefully. After you’ve hung the sleeping bag, take a badminton racket to it.

You can also use your sleeping bag as a pillow by laying your head on it. It consists of a clap and a punch. Grab the bag by the handle. Gently wiggle your sleeping bag to get it ready for bed. Look for any clumps of hair. Break the clumps apart using your hands.

It’s time to wash your sleeping bag if none of the other alternatives work out. As a result, the washing instructions for a Synthetic Sleeping Bag are provided below.

A high-capacity front-loading washing machine or doing the washing by hand in the bathtub are both viable options. Washing machines with top-loading tubs are particularly harsh on the bag, causing it to tear.

When a sleeping bag is described as “lofty,” it refers to how fluffy it is. Air is trapped between the threads, which is what gives the fabric its fluffiness. In order to keep you warm, the sleeping bag functions as insulation.

2. By using a Washing machine:

You can remove the drawcords from your sleeping bag and then zip it shut. Use a moderate cycle on the front-loading washer. Warm water may be used to wash most bags. Look for the manufacturer’s recommendations on the care label.

Use a synthetic detergent. Rinse it twice to remove all soap residue. Rinse and dry your sleeping bag once you’ve put it in the laundry. The weight of the wet down is enormous. Support the bag from the bottom to keep the baffles safe.

3. The dryer process of Restoration: 

In addition to the drying process, you may also use this method to restore. This is how it works:

  • Make sure your front-loading dryer is set to use just air. Take care not to overheat your sleeping bag.
  • The use of 3-4 clean tennis balls can help break up the down clumps.
  • Every 30 minutes, take the bag out of the dryer and carefully break up the clumps.
  • Check for chilly patches by hanging the sleeping bag in front of a bright window as soon as it’s dry. Your sleeping bag should not allow light to flow through.

Your sleeping bag should be revitalized to its former glory after undergoing this technique. It’s time to replace the bag if this process fails.

If you like, you can have your sleeping bag fluffed up by sending it to the firm. You can also get a new synthetic sleeping bag if you choose.

Washing Procedure of a Synthetic Sleeping Bag 

  • Consult the instructions provided by your bag manufacturer (on a label or online).
  • At a laundromat, use a front-loading commercial washer. To guarantee that your bag is thoroughly cleaned, it is best to have larger capacities. If you don’t have access to a laundromat, use a front-loading washer to do your clothes at home. Do not put your bag in a top-loading washer with an agitator column because it may become tangled or coiled around it and cause damage. Hand washing a bag is an option if no machines are available.
  • Make use of proper cleaning. We recommend a technical cleaning for synthetic bags, such as Nikwax’s Tech-Wash. Typical laundry detergent may create clumping or reduce loft, or it may leave a hydrophobic coating on the clothing.
  • To avoid snagging or breaking the slider, open the bag all the way.
  • Wash the bag on a gentle cycle in warm water. Consider following the instructions that came with your bag.
  • Rinse at least twice to remove the cleaning chemical completely. Repeat the rinse cycle if the nylon bag is pooling water or feels spongy. It should be humid and wet, but not soaked.
  • When pulling the bag from the washer, support it from all sides (not just one). This prevents straining and ripping of the seams.
  • Squeeze out any excess water and move on to the drying process.

The Function of the Loft in Sleeping Bags

The Loft in a Sleeping Bag serves a variety of purposes.

  • The fluffiness of a sleeping bag is measured by its loft.
  • Baffle boxes are used to package sleeping bags. Even if the baffles are filled with down or synthetics, the filling should be evenly distributed across the vertical portions of the baffles. As a result, your sleeping bag will perform as expected.
  • The fluffy appearance is achieved because of the trapped air between the threads. Therefore, the sleeping bag serves as insulation, keeping you warm at night.

Normal wear and tear over time might cause the fill in your sleeping bag to degrade, leading to chilly spots on the baffles or in the corners and reducing the insulation value of your bag. As a result, there is a lack of warmth in the home.

It’s possible to fix this issue by rearranging the fibers on the fabric. As a result, more air is trapped between the fibers, which increases the amount of heat that is provided.

Considerations Before Restoring Loft to a Synthetic Sleeping Bag

Oil build and human sweat cause synthetic sleeping bags to lose loft. They lose their loft more quickly and have fewer chances of recovering it back.

Because of this, you should take precautionary measures to avoid future issues. That’s why it’s important to master the basics before attempting to restore loft to a synthetic bag. –

  • When drying a synthetic sleeping bag, you don’t need to use tennis balls.
  • Laundry detergent should be avoided at all costs. Soap formulated for synthetic fill should be used.
  • They don’t respond to cleaning the same way as down sleeping bags do. Since the loft has been cleaned, don’t expect it to be the same.

A professional cleaner can wash your sleeping bag if you don’t want to do it yourself. Rainy Pass Wash offers sleeping bag cleaning services.

Tips for Increasing Loft

The loft in your sleeping bag might be lost due to improper storage and overcompression. More resilient, compressible, and long-lasting down fill is found in high-quality products.

In the opinion of Feathered Friends, a high-quality down-fill sleeping bag can be compacted indefinitely. A filthy sleeping bag should not be crushed in a compression bag for an extended period of time.

Synthetic fibers are less compressible than down. Compression tests on down and synthetic materials were performed by PHD ( a few years ago.

They found that synthetic material loses 30-40 percent of its loft after thousands of compression cycles. There were 5 percent more drops than usual.

That down is more compressible than synthetic is supported by this finding. A dirty, wet-down sleeping bag should not be left in a stuff sack for a long amount of time.

Damage to the fibers that might otherwise contribute to the loft is caused by excessive compressive force. It takes longer for synthetic sleeping bags to lose their loft than natural ones. As a starting step, it’s best to eliminate loft issues altogether.

  • Hang your sleeping bag in the closet or in a large, ventilated cotton bag.
  • When packing a camping sleeping bag, always stuff it in the stuff sack. Your sleeping bag should never be rolled up.

Your sleeping bag will last longer and you’ll save time packing it this way. No more problems with your loft in the future.

Drying Process of Synthetic Sleeping Bag

Synthetic sleeping bags dry more quickly than down sleeping bags. In comparison to a down bag, a synthetic bag will dry in less than an hour. In order to keep warm, you must insulate your loft. The down and synthetic fillers in the insulation must fluff up in order to create small air holes (loft). These areas assist keep you warm while you sleep.

To help you dry your synthetic sleeping bag, we’ve compiled the following guidelines:

  • If at all possible, make use of a large-capacity dryer. Commercial dryers are more powerful and can be used to dry sleeping bags that have been completely lofted. If you don’t have access to a laundromat, consider using your own home dryer.
  • Reduce the temperature of the dryer to a low setting. Fragile nylon fabrics can melt if exposed to high heat. To hasten the drying process, it’s better to dry on low heat for an extended length of time rather than blast it with high heat.
  • Do it as many times as necessary until the bag is totally dry. Take a break and let it run for at least an hour or more.
  • In addition to these methods, you may also air dry your bag, but this will take more time, by laying it flat on a clean surface away from direct sunlight and high humidity. Make sure to equally distribute the weight of the nylon fabric while hanging it up to dry.
  • Make sure your bag is totally dry before putting it in its storage bag by laying it out or hanging it up overnight.

Cleaning Your Bag Spot

Spot cleaning the head and foot sections of your bag before washing the rest of the bag is a good idea because they tend to accumulate more dirt. If your pocketbook is looking a bit worse for wear, you may not need to take it for a full-blown bath. This is how you do a quick and simple job of spot cleaning:

  • The same mild soap you use to clean the entire bag can be used on the spot you’re cleaning.
  • Use a soft-bristled toothbrush to gently scrub the shell.
  • When it’s time to clean, use a damp sponge.

The outer shell or liner fabric should be kept separate from the insulation so that you can wash and clean the outer shell without getting the insulation wet. If the bag’s fill gets wet, allow it to dry thoroughly before putting it away.

How to Keep Your Sleeping Bag From Delofting

Trick number one: Try to limit the danger of contamination on your next journey if hygiene was an issue and you removed a lot of oil and debris.

You can keep your backpack clean by making sure that you sleep in clean clothes. Air out your sleeping bags during the day and use a mat or ground liner at night.

Trick number two: Keep an eye on how you store the bag. Because of the compressed nature of the sleeping bags, there is a significant problem with regard to their storage.

If there is too much air in the bag, it will stale up and become a breeding ground for dirt and moisture. The bag shrinks even further with a vacuum-packed solution.

Keep the bag inside out if the outer shell is watertight. By doing so, you increase the chances of it lasting spotless. Additionally, make sure to check out the available storage options. It’s either clean and dry, or it’s moist and moldy.
