There are many different materials that you can find sleeping bag liners made out of, but silk has to be one of the most comfortable. It feels great against the skin, is a lightweight option that wont add too much weight to your backpack, and will add an appreciable amount of warmth to your sleeping bag, extending your temperature rating by a few degrees or more. So silk sleeping bag liners are a great choice.
Silk Sleeping Bag LinersWhat to look for from a silk sleeping bag liner.
- Hood - This one is more of a personal preference, but if you want a good sleep, and especially if you are looking to add warmth to your sleeping bag, you should be getting a silk sleeping bag liner with a hood. You lose a lot of body heat out of your head, and supplementing your sleeping bag's hood can help prevent that. A hold can also help keep your sleeping bag liner properly aligned in your sleeping bag if you're the kind of person that likes to toss and turn at night.
- Shape - You should make sure to get a silk sleeping bag liner that matches the shape of your sleeping bag. If you have a rectangular sleeping bag then either a mummy shaped sleeping bag liner or a rectangular sleeping bag liner will do, but for a mummy shaped sleeping bag, rectangular sleeping bag liners will be a waste of fabric.
Best Silk Sleeping Bag LinersReviews of the better silk sleeping bag liners out there.
- Rab 100% Silk Sleeping Bag Liner - This silk sleeping bag liner from Rab comes in a wide variety of sizes and shapes, including both mummy and rectangular, for either shape of sleeping bag. The mummy version weighs 4.5 ounces, or 128 grams (the weights on backcountry.com are wrong). There is no word on how much warmth you can expect to add with it, and it also does not come with a hood, which may or may not be what you are looking for.
- Cocoon Silk Mummy Liner - Another silk sleeping bag liner, this time from Cocoon. This one does come with a hood, as well as a drawstring on the hood to keep all of that warm air in. REI lists it as adding 9.5 degrees in one place and 5 degrees in another. 5 degrees is believe, 9.5 less so. It weighs 4.7 ounces, or 130 grams.
- Sea to Summit Premium Silk Travel Liner - Another silk sleeping bag liner, this time from Australian manufacturer Sea to Summit. This one comes in a variety of shapes and sizes, including a mummy shape with a hood. You can supposedly expect 10 degrees of added warmth, though I certainly wouldn't count on that much. The mummy version weighs 4.8 ounces, or 136 grams.
