This is called the MusucBag and is an all-in-one sleeping bag!! It has been around for a few years, and this is a second generation one! Fantastic for festivals, camping, or just lounging around! I have checked the holly tree in the garden, and its full of berries, so according to the ‘old wives’ its going to be a frigging cold winter and i am going to have to get  me  one of  these. Not cheap at £89 but i think its a must have, i will keep mine in my car, as if you knew what i drove you would realise the chance of it breaking down is quite high, and i do not want to be found the next day frozen to the bloody steering wheel, not a good look !!!!
