The format of this quilt is quite what I wanted to use booster that I was intended. Perfect for a casual sleeping because it does not take too much space, will easily fit through a very well studied and practical bag. Moreover, it is not too heavy or thick, although hot enough. I took the precaution airy product before testing. I do not suffer from allergies, but other users' comments had me worried. I must say that the comforter had a rather unpleasant odor unpacking, but it is often the case. I regret that the origin of feathers is not precise, and the absence of anti-allergy safeguards. The Made in China is a bit worrying insofar everything seems possible, the best, in line with our European standards in terms of health, as the worst ... I would not want one of my guests have to suffer from exposure to allergenic or irritant. So it was with some caution that I will use this duvet.
