Criteria Used in Choosing the Best Sleeping Bag Liners

Along with the benefits of using this type of gear will be some decisions to make as far as the materials and shape of the product. Upon investigating you will notice there is a multitude of selections to be made. Hence the reason for this buying guide, we have taken some of the time and effort out of the research for you. Here you will find a list of ten of the best options available on the market to consumers. We have compiled the facts for each product on the list, you will read what others have found useful with each selection. We have also included some of what others have found to be less beneficial for each as well.

Moving forward to the next section of the buying guide, you will notice that we have chosen to include the criteria we used to choose the products we did. This information explains your options for selecting what will suit your needs the best. At the end of the guide, we have dug up some of the more frequent questions that pop up when shopping for an item such as this. Including these will help save you time and frustration when making your selection.

As we briefly touched on above, this type of gear can provide you with several potential benefits. Before making the decision as to which one will suit your overall needs, it is best that you know all of the benefits.

Temperature Control

In some cases, the type of sleeping bag you have chosen can be either too warm or not warm enough. Adding gear such as this can give you another layer inside of the bag to keep you warm. On nights when it is just to warm for a heavy blanket, you can use this as a stand-alone sheet for a light cover.

Cleanliness

Have you ever put any thought into how dirty your camping gear actually is? I mean let’s take a moment to reflect on some instances where you have crawled into bed exhausted for the days’ adventure. We have all been there covered in sweat and dirt from the day but too tired to care. Having an added layer between you and the blanket can help keep it clean for longer periods of time. The dirt and grime come into contact with the lining instead, never touching the blanket.

Prolongs the Life of Your Blankets

Bigger, thicker blankets are not always the most washing machine friendly option. This leads to damaging your gear or less frequency of washing the blankets. Since these are more like a sheet, they fit into the machines much easier. The less you have to place your actual blanket through the wash cycle the longer it will last.

For Your Protection

Perfect for those who enjoy traveling or even for those away on business. You can stash these in your bag for use at those less than favorable sleeping arrangements we often find ourselves stranded in. You can place them on the bed as a barrier between you and those somewhat sketchy looking sheets you are supposed to be sleeping on.

The Bugs

When enjoying the great outdoors, you have to deal with pests as well. Small insects can get to be very annoying when you are trying to get a good night's rest. Using this as an added barrier can protect your skin from those pesky little bugs. There are also versions of this gear available with added repellent to keep the bugs at bay.

The Shape Selection

There are two main choices when it comes to the shape, those that are more rectangular. These can fit into the average bags and are often the selection of choice for those using this gear for their traveling necessities. Then there are the ones whose shape resembles that of a mummy. These will fit snuggly into the mummy-style bags, as they are also tapered toward the bottom as well. This style tends to be chosen by those who are looking to add a little warmth to their night’s rest. As both the bag and the liner provide a closer fit for added warmth.

Materials

Cotton: This material option is one of the more durable and is known for being absorbent. It does, however, take quite some time to dry upon getting wet. Cotton will be more comfortable on your skin and comes at a lower cost than most of the other material choices. You will notice that cotton is heavier and does not pack as well as some of the other options will. This material choice is not always the best when looking to add a little warmth to your night as it has little to no thermal properties.
Silk: Silk can be one of the more beneficial material options for all the seasons you spend outdoors. It feels soft against the skin while having moisture wicking properties as well. This allows the material to dry quickly adding to its ability to control the temperature levels. With all these potential benefits will come a higher cost to the consumer, for some this isn’t an issue. One more thing to remember, wet silk will lose some of its durability, be sure to use care while handling the wet material.
Fleece: Fleece is one of the least expensive options to choose from but still holds plenty of potential for those who wish to purchase it. This variety can boost the temperature within the blankets keeping you warmer on those cool nights. Fleece carries moisture-wicking properties and will dry fairly quickly in comparison to some of the other materials. On the downside of things, it is heavier and has more bulk to it. For those who have space, this option is suitable but for those packing for a hiking trip, you may need to seek a better-suited material option.
Synthetic Blends: Synthetic blends are man-made materials developed for specific purposes. Some are blended to give you a breathable yet moisture-wicking option. While others are blended specifically for keeping you warm. These are typically the most durable way to go as they are also easier to care for. One added benefit is to find an option that provides you with some stretching abilities. This will reduce the chances of getting tangled up at night in the event you tend to toss and turn quite a bit.
Wool: This type of material is known for its warming abilities. The Merino variety is said to be the more comfortable selection. Most often these are a relatively inexpensive option to go with. Some have stated that they are slightly heavier than some of the other materials available today.
Some Extras to Consider

When seeking out an option for warmth, choose one that has a higher heat rating. This rating stands for the warmth that the selection can add to your bag. Most of the time you will find this rating on the tag that holds the specifications of the product.
Weight can play a big factor in the decision that you make. When it comes to the thermal variety they often add the most amount of weight to your gear. In this instance, you will have to ask yourself if the added weight is a necessity.
You can find these to be treated with bug repellent to help keep those creepy crawlers away.
For those who tend to sweat more at night, you may want to consider an option that provides breathability. Blankets tend to get a little stuffy at night, breathable materials also come with moisture-wicking abilities. This will combat the amount of sweating a person can do.

Care Tips

Upon reading the label for many of these you will notice that is recommended to dry these by air rather than in the dryer. Using the dryer can cause shrinking to certain materials. For those options that have cords or strings attached, it is best to take care when placing them into your machine. String and cords will find a way to bind up in the machine, causing potential damage to both your machine and gear. One way to solve this issue would be to place the gear inside of a pillowcase to prevent tangling.

Many of these material options can be washed in your machine at home safely. It is best to use a mild detergent for items such as this. Stronger soaps and fabric softeners can interfere with some of the beneficial properties the materials have.

Materials

This will vary by the opinion of the user. It will also depend on the conditions that you plan to use it in. When the weather is warm or humid, you can certainly replace your blanket with one of these. It is not recommended that you use these in cold conditions, as there just isn’t enough warming potential for that type of use. Some will prefer to use this with their blanket and some ore open to using one without the blanket.

q: What is the best way to wash a liner?

a:

You can most definitely use your household machine for washing your liner. It is in your best interest to use a detergent that is of the mild variety. Doing so will not affect the ability of the product. In the event that your gear has strings, it is best to either tie the strings into a knot to prevent them from tangling or find a washing machine bag. A great at-home hack is to use a pillowcase as a bag to wash your gear.

q: What shape liner will I need to purchase?

a:

The deciding factor for the shape will be determined by the shape of the sleeping bag. It is best to pair a rectangle version with a rectangle blanket. The mummy shape is tapered so it will only fit into the mummy-shaped blanket as well. Many prefer the mummy shape as it reduces the amount of tangling the blanket can do. For those who are using this type of gear as a stand-alone option, the rectangle variety is the best-suited selection.
