A new brand called Grüezi-Bag is presenting its first collection of down sleeping bags at this year's OutDoor trade fair. The owner and founder of the brand, Markus Wiesböck, has worked in the outdoor sector for 10 years. Wiesböck manages a sporting goods and outdoor store in Kolbermoor in Germany, called Sport Go West, that specializes in mountaineering and trekking. It was there that he got the idea to design and develop sleeping bags that are fashionable but also functional.
