This mat does not roll an how the cost variations, is very soft, so the joints do not ache in certain exercises (specially the knees and elbows). As for the "unpleasant" artificial fragrance, so this is not as unbearable as some write here, especially since the volatilized itself. Almost completely after a few days
One must still say that this Gymastikmatte is heavier than the Allte billge, but is not worth talking about, who do sports make this the weight of nothing. As for the price, well of course, could be less, but with such a good yoga mat, it is OK that this costs a little more.
