Let us explore further why and how we can make the most out of our favorite sleeping bags with the help of these trendy sleeping bag liners.

Factors To Consider Before Buying

We can accomplish anything in the world with a good night’s sleep. Although it often eludes us, that should not be the case while we are out conquering the world one camp trip at a time. We need a refreshing and deep sleep every night on our trip to enjoy throughout the day, at least at our leisure camping time.

This is when the very useful sleeping bag liner comes into the picture. It protects us and our sleeping bag both from all kinds of elements that might be harmful. Also, it is extremely portable which makes things even easier for us.

1. Shape

The two main shapes in which the sleeping bag liners are majorly available to include the Mummy and Rectangular shape. Each one fits a specific bill and lacks in a few other sectors. Most of the people, however, are biased towards the rectangular shape liners. This is because they give more room to the user for free movement while using it.

The mummy liners, on the other hand, come in handy when we require a snug fit. This requirement can be because of the protection required from the bugs in the wilderness or from the chilly weather. But once we are inside the bag, the movement of our limbs is mostly restricted that might not be a comfortable situation for most of the people.

At present, these two sleeping bags are supposedly doing well in a number of terrains. And that helps us in narrowing down our choices more rationally so that we end up with the best option that the market has in store for us.

2. Size

While on a hike or any other similar outdoor activity, we require the basic gears but we don’t want to be weighed down by them. This is why it is better to invest in the lightest and most compact gears that will get the job done for us without weighing us down. The sleeping bag liners that we carry along with us need to be of a similar nature too.

Mostly, the silk and polyester sleeping bag liners are the ones that save enough space for us without having us make a huge sacrifice in terms of quality. That is why most of the smart campers go with either of them while going out on a hike with friends and family.

We want our food, water, sleeping gear, and other essential necessities to fit in just one bag. This indicates that the silk and polyester liners are our best bet when we are planning to make our carry bags as light and compact as possible.

3. Warmth

Just because the weather decides to play games with us does not mean that our hiking or trekking plans should suffer. If the winter is coming then we will conquer it with all our might! Polyester and microfibre sleeping bag liners are the ideal choices for colder temperatures.

They are strong, compact and add the much-needed warmth to our sleeping bags so that we always sleep like a baby even in the face of a blizzard! We don’t shiver to sleep. That just means that it is going to be yet another endless frigid night where we wait for the sun to come up and thaw us back to life.

But when we have the warmest of sleeping bag liners at our disposal then it makes no sense to let our body suffer like that. It is only after a warm and cozy night of sleep that we will be able to march on into the face of the freezing peaks and win over every challenge that nature might throw at us!

4. Material

Nowadays, the sleeping bag liners are available in a wide range of material. Cotton, silk, microfiber, and polyester are the four main materials in which the liners can be found largely. Microfiber liners are the bulkiest and they are mainly used when we require a warm lining to our sleeping bags.

The cheapest liners are made of polyester but it takes a toll on the skin hence not the most ideal for frequent use. Then comes the cotton ones that are considerably cheap and quite easy to wash also. But inside them, you will often start sweating soon.

It will make the insides of the sleeping bag smelly and unhygienic pretty soon. Silk bag liners are the best and fare outstanding with respect to various criteria. They are a bit high on the price but they also justify it well with the luxurious comfort which they deliver.

5. Beats the Bug Bites

It all comes down to our choices. We can either suffer the toxic insect bites while camping out and sleeping inside our sleeping bags. Or we can treat the back and front of it with insecticides to enjoy that elusive deep sleep all the time. Even when we choose to slumber under the stars, fireflies and everything else that the jungle might have planned to annoy us with.

Permethrin-treated liners are a good option when we know we are going to a mosquito or other insect-borne place for hiking pretty soon. Or we can treat the liners ourselves with the help of an aerosol spray or pump.

This spray will stay effective for a lot of use even after multiple washes. We just need to make sure that we are not highly allergic to them. Ideally, the insecticide treatment of the liner will help us to explore the unseen without much trouble.
