Overall the only thing to remember is that this is a cap 3, he is very clear as it could have been sold between 5 and 10 but do not expect to have the insulation of the century as the cold pass little, but not being someone chilly and having taken more for its style as for its effectiveness I do not hold it against him. As always pleasantly surprised by the speed of delivery which, as for each of my control item arrived ahead of schedule by Amazon which makes me a surprise every time. For the price frankly we can consider that it's free, I am a complicated but I would recommend this product to anyone! Only small problem that will differ according to the person that is the hat itself and this gift is made because it has the tendency to accumulate a lot of static electricity which the gift of ruining your hair (if made without gel or lacquer etc) and requires you to wash your hair even if clean to remove all this accumulation of energy in the hair, but that's just a detail, five star product!
