Awesome liner. I don't like the silk personally but I love this material. It works really well for tropical conditions and I would recommend to anyone backpacking/camping with 70+ nights or if your staying at a hostel. I also carry the marmot trestles trail bag in case the temp goes below 65(f). I also like the fact that I have a nice wicking liner for colder months. I tend to sweat.
This bag when packed is 3x5 inches. I am 6'3" 250lbs and I fit comfortably.
