After 8 years I think I like it even more!! Super warm, and light (+/-4lbs 9ozs).. not one problem or fault and it's got many miles on it. Well designed, well sewn. ID will customize, I had 1 extra oz. of down put in the foot area baffles - was given excellent advice re putting in too much extra down...mine built for -40s weather with Gore DryLoft.
Can't think of one complaint - I even got to pick my colours! A great bag.....
