Brilliant bag - I got the boat-foot version. Never had any problem with not having a neck baffle. Not light, but then again some of the lighter bags I've had didn't keep me as warm as they said they would!
Wiggy has made a lot of enemies in the US outdoor forums because of his outspoken defence of his gear. And from my dealings with him buying some stuff, he can be very ... abrupt! BUT
He is the only sleeping bag or clothing manufacturer to guarantee his products for life against loss of loft or failure. (and honours that guarantee regardless of age of the product)
He claims his bags can be stored- for years if necessary - fully compressed in their compression sacs without damaging the loft.
He is the only manufacturer of synthetic - or down - bags to recommend frequent washing of his gear, even in home washing machines. (And one thing I've learnt over the decades is that sleeping bags become less efficient the more they are used, primarily due to the dirt and sweat and body oils flattening the loft)
So I'll put up with Wiggy's ego and occasional rants because his gear works.
Now I know that lots of BCUK members have favourite manufacturers and get very proprietorial over them. But the simple task I put to you for those who press their praises for Marmot, Snugpak, Ajunkilak, North Face,Kifaru etc etc - is to ask them to match Wiggy's lifetime guarantee on loft and construction (or even washing frequency). And they won't. That should tell you something
Oh, and a youtube video I came across
