I had the great pleasure to meet Carol McDermott, co-founder of Crux & Lightwave, yesterday. The gear freaks amongst you might be interested to know that Crux is preparing to extend their product lines to include a top quality down sleeping bag range. He gleefully showed me a sample model that incorporated an eVent outer fabric bonded via some rather cunning process. This kind of thing has been done before with GoreTex (by PHD...) and Conduit by Mountain Hardwear, but I am not aware of eVent being used in this manner by anyone else?
Apart from the target market of alpinists looking to stay dry in a snow hole etc., I suspect this might be a good product for those of us who like to tarp camp but worry about using down without a bivvy bag.
