The Jagbag endura sleeping bag liners are wonderful. They are pure silk, wick moisture, keep you warmer in the winter and cooler in the summer, and the silk itself is luxurious. BEST of all they are very affordable due to the difference in currency values between US and New Zealand. I am going to have to get some silk sheets and pillow slips from them too! Full review
