Exped Silk and Thermolite liners (seconds) 22% retail

I don’t know about hiking, but those look like a great idea for someone who might have to sleep in a hotel where you have doubts about the linens.

At this price worth experimenting with. Thanks for posting Monte. Does anyone have any insight into the thermal increases claimed?

I’ve never used a silk liner, but do have experience with a Thermolite liner.  I never thought it added much noticeable warmth.  I also found it to be futzy…it is so thin that it gets wound up around your legs if you toss a bit in your bag.

For approx. the same 10 oz that Exped lists, an Alpha Direct top and bottom would add WAY more warmth albeit at a much greater cost.  Honestly, I think a 150 or 200 weight merino base layer would be better than the Thermolite liner.

While the (sale) price might make it attractive, ultimately you get what you pay for.

I would definitely opt for the silk over the Thermolite. A little better warmth to weight ratio. Also silk is usually a lot more expensive than synthetic.

Some years ago I had the S2S Reactor liner that weighs 8.7 oz and rated at 14* added warmth and the S2S Reactor Extreme (14 oz) that’s supposed to add 25* warmth. I found the claims on both to be WAY overrated, maybe half of what S2S states, if even that. And they’re not cheap either.

I bought a 7 oz silk liner by Thermasilk off Gearswap a couple of year ago and I find it does pretty well as a stand alone summer liner or when paired with my Montbell Breeze Dry-Tec WPB bivy for XUL missions in temps above 58* F.

I bought a couple of these and just received them. The quality is nice. I got the rectangular in blue and weighed in at 133g without the stuffsack.
