Anyone used them? I'm curious if they are any good. I've read just about all the stuff Mr. Wiggy writes on his website - his criticisms of other products seems to be spot on in my experience, but the question for me is whether his product lives up to the hype.

His sleeping bags do in my experience.

I don't use packs, so haven't used these. I agree, the bags work. I think Wiggys would do better with a little softer sell, but I like the stuff I have from them.

My Tule Ultra light had two spots with very little insulation. Took it for Jerry to look at had one of his sewers disassemble it in front of us. Yup, two spots that had no insulation.. Jerry Wigutow: “I see nothing there that could cause cold spots, nothing wrong with it, you need to buy my fishnet underwear and sleep in it”. Nuff said.
