WExcursionistas build their sleep systems, the basic concepts are the first: a sleeping bag and a pad. But sooner or later, the question of a sleeping sack lining arises. Some backpackers swore for them, others discard them as an extra weight. The truth is that the coatings have a specific purpose, and if one needs one depends on their priorities along the way.
What is a sleeping bag?
A sleeping bag is essentially a light blade, usually made of silk, polyester, cotton or specialized thermal fabrics, which slides inside its bag. In its simplest form, it is another layer between you and your isolation. For some hikers, that additional layer makes the difference.

Why you should use a bedroom sack for backpackers
One of the greatest benefits of a lining is heat. Thermal models can add several degrees of isolation, which can be the difference between shaking overnight and sleeping comfortably.
Under unpredictable conditions or shoulder seasons, a coating can extend the temperature range of its bag without requiring that you invest in a heavier and bulky model. In hot climates, the opposite is true: you can leave the bag unfocked or even omit it completely, sleeping only under the coating.

Cleaning is another advantage often overlooked. Sleeping bags, especially the bags below, are difficult to wash, and wash them too often can shorten their useful life.
A lining acts as a barrier against sweat, body oils and dirt, maintaining its freshest bag for longer. Unlike a bag, a lining is easy to throw at the end of the trip or halfway through a walk. For anyone who invests in a high -end sleeping bag, this protection can be worth it alone.
Comfort also plays a role. The material of a coating can drastically change how your sleep system feels. Silk and polyester linings feel soft and soft against the skin, while cotton can feel more familiar, such as house sheets. On long trips, when sleep quality directly affects daily performance, that little comfort can import more than you could expect.
Why you shouldn’t wear a sleeping bag for backpackers
Of course, the coatings are not inconvenient. They add weight and volume, which minimalist hikers will notice immediately. Even the lighter options generally enter a few additional ounces, which is a weight that could otherwise be stored.
Coatings can also be a discomfort. When sliding into a lining inside a mummy bag, it requires patience, and after a long day of hiking, some people find that the process is restrictive or frustrating.
And then there is the cost: a good thermal lining can work between $ 50 and $ 100, which is money that prefers to allocate to the update of its bag or pad first.

What have we learned?
So, do you need a sleeping bags for backpackers? The answer is situational.
If it is often in variable conditions, you want to protect a expensive bag or is going on a long trip where regular washing is not an option, a lining can be an intelligent addition to its kit. If most of your trips are short, predictable or already covered by a bag with rating for the lowest temperatures you expect, a lining may seem an unnecessary weight.
In the end, a coating is a tool that is useful for many hikers, but not essential for everyone. It offers versatility, cleaning and comfort, but if it wins a permanent place in its package it is reduced to its backpacking style and the conditions it faces.
