Thanks for the suggestion alan de enfield[/size].
I'm currently struggling with a Snugoak Elite 4 and by struggling I mean with the compressed size and not with the weight (1900g) or performance. Really like the warmth, shape and ease of use for this bag and as I'm a side sleeper, I tend to sleep more in an 'S' shape so I can shorten the bag to increase the warmth with the clips.
It would appear that the OEX bag could give similar performance for a lighter weight plus being down it should pack down slightly smaller (than my snugpak at 28 x 24cm)
I have one and it packs down to less than 23 x 19 (the size of the bag). It could be packed down a bit smaller. I reckon 18 long x 18 diameter is achievable.
The OEX is not really much of a tapered bag (I find a bag that is body contoured to be very restrictive and similar to being in a straight jacket) I am a side sleeper (Z shaped) but do tend to roll about / roll over quite a bit and find it a 'good size and fit' for me.
I am 6 foot and 14 1/2 Stone (about 92 kgs in foreign money)
