    Makes Me Feel Sophisticated

    • Familiarity: I've used it several times

    I don't think I'll ever be fancy enough for silk sheets, but the sleeping bag liner is an excellent alternative. Super soft and comfy! The stretchy side panels are a great touch–you've got a little more room for getting in and out of the liner, and for rolling around if that's your thing. Besides actually using the sleeping bag liner as a sleeping bag liner, I'll definitely bring it along on non-camping vacations. Highly recommended.


    • Familiarity: I've put it through the wringer

    I love these bags. They are great for adding a little extra warmth to you sleeping bag. What I really like them for is traveling. Keep it in your carry-on so you have a light weight blanket on the plane. It worked really well in Indonesia to keep me off some of the questionable places I was sleeping. It also made a nice light sheet and helped wick sweat on hot humid nights in the jungle.

    Light and Feels Good

    • Familiarity: I've used it once or twice and have initial impressions

    I got this liner to pair with my new WM bag to help extend the life of that product, so that I can just wash this liner as opposed to the whole bag. It does feel really good against your skin, and the stretch panels keep it from feeling too constricting. I also like how light it is and easy to pack away in the included pouch.

    Very light and comfortable

    • Familiarity: I've used it several times

    I was initially concerned about the stretch panels but they are strong, not at all flimsy as I was worried they might be. They do definitely add to the comfort of the sleepsack. I believe I now prefer the stretch panels over the Velcro tabs of my now thread bare poly sleep sack.

    Silk is the way to go if you are able. Light, excellent in all temps, great odor control (naturally), and durable. I will definitely buy this again if I should happen to wear this one out.


      Couldnt find my dated silk liner for a trip so broke down and bought this. As silk liners go, don?t think you could get much better. Its thin and light. The spandex sides seem to give some extra flex and movement (I slept IN this liner, on an exped mat, with a UL sleeping bag draped over as a blanket on a recent desert trip?setup was comfy and warm. My other silk liner has a slit down the side with Velcro to attach up the side?minor annoyance for me but I spent a decade being itched/irritated by the Velcro patches as I stirred/moved at night. This one has no such slit/Velcro/zipper but does afford ample movement. You will, however, have to enter/exit the liner on the end rather than exit the side as you would your bag. Again?the spendex side panes afford plenty of movement to be able to get in & out easy enough.

      What do they mean when they are talking about "stretch panels?"

      What warmth does this liner add to a sleeping bag? The Reactor Extreme specifically says 25 degrees F..

      I've been looking at the Sea to Summit Thermolite Reactor Extreme Mummy Bag Liner, and plenty of reviews from users who've field tested it say it doesn't get anywhere near the added "up to 25 degrees F" warmth claimed in the specs. Compared with that product, how much added warmth can we expect from the silk liner? Are we sacrificing comfort for warmth, or is silk a win-win, with the caveat that it's more expensive?
