optical class and practically perfect - only one shortcoming is the smell

The bag itself is absolutely perfect for the price. Just as I had imagined.
But for the chemical, absolutely biting smell after you've unpacked the bag I subtract 2 points, because air out even after long and now 3 days of use you realize the "chemical smell" still. It is not possible to pack the bag in the morning with sports stuff you want to put on the evening, the clothes smell horrible.
So I can only guess - LAAAAAANGE airing !!!! because I think, unfortunately, can not avoid the smell in the price ... because production is just there where it is cheap and the material does not cost much - I was soagr already thinking if I return the bag
