Exped WB (waterbloc) sleeping bags.

I have not tried them, though I have tried similar Goretex versions. The problems are several fold for me:

-packing my bag with a wet outer shell was a disaster. If the day warmed up, the moisture got pushed back through the membrane and made the down damp

-Exped bags are not really UL by my standards…a 1250g bag with a women's comfort rating of +3 C/37 F (and 750g fill down) is not impressive, even with a waterproof cover.

-The Expeds use Endurance fabric, which is not truly 'waterproof'. It claims a hydrostatic head of 1,000mm, compared to something like eVent fabric with a hydrostatic head of 30,000mm…I have had my Endurance bivy bag wet-out from moderate but steady rain.
