I was pricing out some backpacking items at my local Cabelas today, and one of the sales associates showed me these sleeping bag liners that he recommended for adding a few extra degrees of warmth to a sleeping bag. The brand was called SeaToSummit and they were called "Reactor Thermolites" opposed to ones that did not really add any additional warmth. They look very compact and light weight.Anyone use one? Do they work pretty well or are they just more of a hassle? I'm thinking of getting one so I'd be able to get a bag rated for a little warmer temp and have a system that is less bulky and more versatile.
Thanks!
