I'm after a new sleeping bag for the upcoming winter months, and i'm planning the West Highland Way at around easter next year. So with that in mind i'm going to be buying a new bag, down or synthetic i havent decided yet, but i'd like it to meet the following criteria: 1kg or preferably less. comfortable at 0*C (i dont mind layering w/ my clothes) Target price £150 so based on the price i'm looking for an older model, or would consider a lightly used bag too. I currently have a Green AegisMax bag, which has been fine for the summer, so i'm considering converting it into a quilt, and using that in part of a layering system maybe? maybe pair it with a Rab Nutrino 200? So does anyone have any recommendations to fit me needs? I'm conscious of taking a down bag on the WHW, due to a chance i could get rain for days on end, which would potentially ruin the trip if the bag got wet somehow.
