There are a lot of materials that get used for sleeping bag liners, but a silk sleeping bag liner has to be some of the most comfortable liners around. They don't exactly fit with the whole lightweight backpacking philosophy, but they are a nice luxury item if you are okay with carrying a few extra ounces.
Silk Sleeping Bag LinerIf you're looking for a silk sleeping bag liner, you wont do better than these options.
- Cocoon Silk Mummy Liner - This liner from manufacturer Cocoon will add a good amount of warmth to any sleeping bag, and help keep it clean too. You can expect about a 5 degree F boost in temperature, and you get that for just 4.7 ounces in weight, which is 130 grams. It comes in just a mummy shape, and features a drawstring hood, which is a nice feature to have on a sleeping bag liner.
- Sea to Summit Premium Silk Sleeping Bag Liner - Another silk sleeping bag liner, this time from Sea to Summit. The claim is that it adds a full 10 degrees of warmth to a sleeping, which if true, is very impressive. And it delivers that 10 degrees of warmth for just 4.4 ounces, or 124 grams for the mummy version, which is even more impressive. Another nice touch is that you can get a pillow case built in, so if you do take a pillow with, or alternatively you want something to stuff clothes in to make a pillow, you have that option.
- Rab Silk Sleeping Bag Liner - Rab, a manufacturer well known for their well made sleeping bags, also has a silk sleeping bag liner on the market. This one comes in a variety of different shapes, but the mummy version weighs in at 11 ounces, or 340 grams. No word on how much added warmth you can expect, but for that much weight you would expect it to be quite a bit.
- Mont Bell Silk Sheet - One more sleeping bag liner, this time from Japanese manufacturer Mont Bell. It's a mummy shape, and while Mont Bell is sparse on the details, it weighs 6.2 ounces, or 175 grams, so you should be able to expect at least a few degrees of additional warmth.
Why Take a Silk Sleeping Bag LinerIf you've never used a sleeping bag liner before, or are hesitant to add extra weight to your backpack without needing to, here are a few reasons why you might want to at least consider a silk sleeping bag liner.
First, if you are going to take any sleeping bag liner, silk is probably your best option. It adds a respectable amount of warmth but weighs relatively little, compared to other materials like fleece or cotton.
Second, a silk sleeping bag liner is a nice bit of luxury. Personally I've never liked sleeping with my bare skin against nylon, and I find a sleeping bag liner to be the perfect solution.
Third, you can expect a few degrees of warmth to be added to your sleeping bag. If you are going backpacking or camping with a sleeping bag that is not quite warm enough for the weather you are expecting, a sleeping bag liner is one way to add a little warmth to your sleeping bag. Whatever happens, you want to be able to sleep all night long, rather than shiver all night long.
