In reply to purplemonkeyelephant:
Why do you want it synthetic??
Wiggys are not that good, and are heavy. Half way up Denali ten years ago (summer) I wasn't exactly grateful for his no-quibble guarantee when the zip and seam split.
I've met Jerry, and he bangs on about filament construction, polymer bonding, and molecular structures like he's trying to convert me. It's a product thats trying to duplicate down. Buy a down bag. Buy a PHD.
Lamina's are great bags, especially for the money. Want a better bag, pay more money.
North face bags for serious conditions are not what they once were. Buy a Mammut (Ajungilak) if you want a top-end synthetic.
