In reply to johnswani: i have a skyehigh 1000 sleeping bag. it has kept me very warm, sometimes a little bit too warm in scottish winters. I would however not recomend getting that one. the skyehigh 800 would be better for scottish winter stuff or the best pipedream one (i think its the 800?). the packsizes are a little on the large size and i would say you would want to get a diffrent compression sack. i use my old snugpack one and it makes it quite abit smaller.
if i was buying again i would get the pipedream.
but for the money you cant really go wrong
