Quality 4 season sleeping bag from Mountain Equipment. The serial number suggests 1970s I suspect it was the early name for what became the Snowline bag, but it is earlier than Mountain Equipment's own records. 70cm width at top, 200cm long weight 1550g Still in good condition - no damage or marks. It has been down washed and refluffed and is ready to go. It's just too warm for anything I do these days.
