Eberlestock Sleeping Bags?

[theedz]

Just wondering if anyone has experience or even seen one in person? They have three models with different temp ratings. Just wondering if those are acurate or not. Also wondering what the outter material is made of? or what it is like? Basically if it is very tough or not? I see the lightweight one has a decent weight (if correctly stated) and seen a picture somewhere of it compressed and seen very small. Just thought I would ask since you guys are the Smartest People in World!!
