  • A new addition to my standard packing 4th June 2013 45 I like to travel light, but I also tend to stay in some less than luxurious hotels where you do occasionally have to grin and bear the bedding shall we say. Enter this light-weight, slightly thermal sleeping bag liner. I used it recently in Anatolia where you are infrequently supplied with sheets to accompany scratchy, grubby looking blankets - so this was a delight. Added a little bit of additional warmth in cold mountainous climates and was an effective barrier between me and aforesaid grubby scratchy blanket. Its now a mainstay of my standard travel kit!
