How to Select the Right Sleeping Bag Liner Material


 Getting a clean, comfortable night’s sleep is a high priority for any traveler – from rugged mountaineers to island-loving hostel surfers. Finding the right sleeping bag liner can make all the difference in the quality of your globetrotting rest. Still, how can you figure out the best material for sleeping bag liners?

 

COCOON is here with a comprehensive guide to choosing the right sleeping bag liner material for you. First, let’s talk about how a sleeping bag liner can enhance your adventures and what factors to have in mind when narrowing down the best sleeping bag liner material choice.

 

Sleeping Bag Liner Uses

 

For starters, you may wonder if a sleeping bag liner is worth having. Would you use it enough to justify the purchase? Experienced travelers are surprised by how often a sleeping bag liner comes in handy.

 

 

Here are just a few key uses for a sleeping bag liner:

 

 

  • Adding insulation to your sleeping bag on chilly nights.
  • Giving you a cooler sleeping option in warmer environments.
  • Boosting overall comfort in off-the-grid environments.
  • Promoting hygiene in high-traffic locations, like hostels.
  • Keeping your sleeping bag cleaner for longer.

 

Sleeping bag liners are super nice to have on hand, helping you pull off a cozy night of rest even in a harsh or less-than-hygienic environment.

 

Now that a sleeping bag liner is on your ‘must-have’ list, let’s highlight some key considerations before committing to any given material.

 

Factors to Consider When Choosing a Sleeping Bag Liner Material

 

As with any purchase, it’s wise to establish some criteria when connecting with the right sleeping bag liner. There are several great material choices, so take time to define how you will use your liner to see which material best fits your needs. Here are a handful of factors you may want to consider:

 

 

Temperature

Your ideal material choice for a sleeping bag liner largely depends on how warm or cool you want to be. For example, a medium-weight microfleece liner can add 14.3°F to your sleeping bag’s temperature rating. Meanwhile, an organic cotton sleeping bag liner will only add about 5.3°F. Many hikers are only interested in sleeping bag liners for warmth and therefore are searching only for cold-weather sleeping liners to add to existing sleeping bags. On the other hand, many people may be planning to sleep in warmer weather and may only need a liner without a sleeping bag, so choose the material that best suits the needs of your adventure.

 

Washing and Care

 

Find a sleeping bag liner material that will be most convenient for you to keep clean as you travel. Some liners, like cotton, polyester, and fleece, allow for machine washing and tumble drying. Other materials, like merino wool, require hand washing.

 

Did you know? The founder of COCOON was almost swept away by a river in Bali while trying to wash a bulk, sewn-together cotton sheet. That’s when our story started, and that’s why we understand the importance of ensuring our products are designed for easy care.

 

Adventure Type

 

At COCOON, we recommend different sleeping bag liner materials depending on what you plan to do. Our guide will help you pick your perfect liner, whether on a bike tour, camping, or hitting up youth hostels.

 

Dimensions and Weight

Some adventures demand that you keep a very low profile. Backpackers, for example, can’t justify packing anything too heavy or bulky. If you’re looking for an ultralight sleeping bag liner, opt for silk (4.7 oz.) or Thermolite Silkweight (5.6 oz.). Both of these options add over 9°F to your sleeping bag’s temperature rating without weighing down your pack.

On the other hand, if weight isn’t such an issue, spring for a microfleece medium-weight liner. It’s 2 lbs. (still very lightweight!) but will add 14.3°F to your sleeping bag’s temperature rating.

Sustainability

Making sustainable material choices is a huge priority for eco-conscious travelers. COCOON has been a member of the Business Social Compliance Initiative (amfori BSCI) since 2012. We have already made significant sustainable changes to our company and have more measures planned for 2023. Several of our liners are made from 100% recycled or organic materials.

For example, our organic cotton MummyLiners are made from 100% GOTS (Global Organic Textile Standard) certified organic cotton. Additionally, our COOLMAX and Thermolite products are made from 100% recycled materials, and our polyester fabrics are PFC-free. Beyond that, all of our packaging material is 100% recyclable.



Now that you have the above factors in mind, let’s dive into your sleeping bag liner material options.
