Jag Bag Silk Liners

I have two homemade sleeping liners at this point. One is a fleece liner with a half zip. It can actually be used for really cold weather to line my sleeping bag and add a couple of degrees to my overall sleep system, or it can be carried alone during the warmer months with cool nights. The other is made of some stretchy polyester material I got in a clearance bin at Wal-Mart with a half zip in it. I like both of these liners, and they were inexpensive, however, they were a little on the heavy side.

So, a few months ago I decided to purchase a silk liner for three reasons. The first is to keep the inside of my sleeping bag somewhat clean. The second, was that I secretly hoped that it would add a few degrees to my overall sleep system, and the third was to cut down the weight from my homemade liners.

While trying to decide which liner to get, someone turned me on to the Jag Bag silk liners. From word of mouth, they sounded good and from the web site they looked good. Plus they were priced great! So, I decided to get one.

When I purchased the liner I decided on the fine silk over the Endura silk mainly for the difference in weight. I got the blue multicolored fine silk liner (seen in picture above to the right ~ the blue one…) I have used it a few times in the outdoors as well as multiple times indoors and have been really happy with it so far. I then did a little write-up and posted it here on my site. Sometime after, the owner of the Jag Bag company contacted me and thanked me for the review and offered me the opposite “bag” for a comparison. So, a very few days later I received the Endura silk liner in the same cut as the fine silk liner I had previously purchased.

In the FAQ section on the Jag Bag site some of the customers have stated that with “the addition of an endura silk sleeping bag liner increases the warmth of their sleeping bag to the warmth of close to 10 degrees Fahrenheit (5-6 C).” The advantages of the Endura silk over the fine silk is that the Endura is stronger, warmer, and has better wicking abilities. This is what Jag Bag has to say about each:

“Endura silk” is stronger than the fine silk and is best for heavy use over long periods. It can be used as a stand-alone summer sleeping bag. It has better wick ability and also inside a sleeping bag it adds more warmth than the fine silk liner. It will last for many years. “The Lightweight Fine silk” is best used when every ounce or gram is important as during expeditions or mountaineering. The silk is very fragile and will not stand prolonged use without becoming bruised. It is fine for brief trips.

When I received the liner I immediately pulled the liner out of its stuff sack to feel the material. I was curious as to how much thicker it may feel than the fine silk liner. To my surprise, I did not feel as much of a difference as I thought I might, however there was a difference. Also, I did feel the slightly “grimy” feeling that I first noticed on my fine silk liner when it arrived. (I hate to describe it this way, but it’s the word that comes to mind. It is not a dirty feeling though. I believe that it is a result of the silk being dyed. After a few uses it no longer feels this way and is very soft against my skin.)

The next thing I did was lay inside the liner to see if it was as generously cut as the fine silk, and it was the same. I also checked the stitching and it appeared to be well sewn. I have noticed that where the liner opens up to crawl in, there is some reinforced stitching since this is probably the first place to become stressed when entering or exiting the liner, which is a good thing. Of course the fine silk is also reinforced in the same way.

Next I weighed the liners. The fine silk weighed exactly 1 oz less than the Endura silk. Both of these liners were weighed inside the stuff sacks which came with the liners. (After seeing this I kicked myself for not going with the Endura to begin with ~ however, light-weight is all about counting each ounce…) The exact weights can be seen in the picture above.

So, now I am just waiting to take the liner out in the field. My wife and I are planning a 9-day trip to thru-hike the Great Smoky Mountains in October so this will be a great time to put them both to a good test! (And one is pink which she loves!) I will be sure to report back here with my thoughts on both the liners once I return from this trip.

I would like to thank Jag Bag for both their fine products as well as their excellent services that they have provided me with thus far. (Also for the extra liner that they sent me. :))

Disclaimer: After purchasing the first Jag Bag (blue one) and then producing a review here on my blog, Jag Bags offered me another complementary Jag Bag(pink one) in exchange for a review.

About Stick

My blog is essentially a record of my hiking career. Through it, I, and others, can see how I have evolved from a heavy weight backpacker, to a smarter, more efficient, lightweight backpacker. Through the use of video, still photos, and of course writing, one can see my progression, as well as check out some of the places I hike, and not to mention some cool, lightweight gear options. For me, my blog is a journal, but for others, I hope that it is an interactive learning tool to aid them in their own progression towards lightweight backpacking.

    how did the endura jag bag work out? I’m thinking of using one for a summer tq in the hammock….and then using it inside a 50 degree tq from hammock gear, to hopefully get my down to 35/40 degrees

      The Endura Silk Liner is a little thicker than the Fine Silk Liner, but on their own I cannot really tell any difference. I have tried using them on their own under a tarp in temps around 60 F and I was a little cool in them. The only time I think they would work well on their own is in temps over at least 70 F.

      In a bag, I would say the most that the Endura liner added for me is maybe around 5 F, at the most. And to be honest, I wouldn’t rely on that since so many other factors come into play (such as shelter used as well as your personal, current physical conditions and the environmental conditions). Not to mention that what may work for me will probably not work for the next person.

      I will admit that I have stopped using them inside sleeping bags because they can be a bit of a tangle for those of us who may toss and turn inside the bag. I will say that I have enjoyed using them under a top quilt that is laid completely open in warmer temps. The liner will help stop drafts that sneak in, and by this I do feel a little warmer. However, inside a hammock, drafts should not be an issue.

      Anyway, hope this helps some.
