In reply to TobyA:
Hi Toby,
Thanks for your reply, I actually came across your review already, researching different bags.
We realise that something like this is not entirely about skiing but that's also the point. We love getting up mountains by any means just for sake of it. If there is an awesome Freeride to be earned it makes both ascent and descent even more epic.
We will nevertheless practice winter camping separately before we go full out. And we will also try to avoid extreme temperatures below -20 if possible but we ought to be prepared for them anyway.
Do you remember by any chance which model that ME bag was you borrowed? And if you had the choice would you take the Snowline SL again rather than a warmer bag despite needing considerably amount of clothing in certain temperatures?
The weight makes it certainly attractive but then again Rab Expedition 1000 or WM Lynx would only be ~300g heavier but considerably warmer.
Can you possibly compare the Driloft outer fabric with other fabrics used for winter sleeping bags? eg. Pertex Endurance, GWS, DryQ/eVent, ...
