Love Wiggy's. 2 decades of heavy use & my bags are still going strong. I accidentally went swimming in January in a blizzard. I slept on top of the snow in the storm with my FTRSS set up. I'm convinced the bags kept me alive. With wet clothes and 18 inches of fresh snow overnight the next morning everything was dry. I was warm as soon as I got my clothes off in the bag and slept great all night. The bags are worth their weight in gold as far as I'm concerned.
