How to Choose the Best Sleeping Bag Liner

Sometimes when you’re camping, you just need a little bit more warmth. Whether your cold weather mummy bag needs a little more heat or you like to sleep with a light covering at night, the best sleeping bag liner is just what you need. We researched the best brands and top-rated products and put together this buying guide to help. Before we get started, let’s take a look at some of the key things you need to know.

Best Sleeping Bag Liners

Material: Some of these liners are made of warm fleece and plush microfiber while others are either satiny polyester or cotton. They’re all durable and machine washable but remember that different fabrics are better for different seasons.

Best Sleeping Bag Liners

Season: Warmer materials are great for winter. Using them inside a cold weather sleeping bag can add up to 15 extra degrees of warmth. Thinner liners that are silky or made of thin cotton are perfect for warmer nights.

How to Choose the Best Sleeping Bag Liner

Zippered: Zippered bags easy to get in and out of but there are some downsides. They can get stuck or snag the fabric and, if you unzip them to get out of your bag, you lose a lot of the heat.

Best Sleeping Bag Liners

Carrying Pouch: All but one of our picks comes with a convenient carrying pouch. This is really the easiest way to travel with these liners. They’re small and can easily be tucked into or attached to your pack.

Best Sleeping Bag Liners

Size: This is how big the liner is when it’s folded for use inside a sleeping bag. Some of these fold up impressively small to be tucked into the carrying bag so we included some of those measurements in the reviews, too.

Product Intro Icon

Warranty: These warranties vary a lot from product to product. While there was no warranty information provided for a lot of these liners, others have warranties that last 90 days, 5 years, or even up to a lifetime.
