The number on the rare of the bottle is 7 which ment that this kind of material is very dangerous
Thank you for your review of the Plastic Hiking Water Bottle 500 Quick-Opening Camp 0.8 Litre (Tritan) Green. To get a better understanding of the plastics, I have been in contact with the Product Engineer who is able to explain the plastics "numbering" system. This is their reply:
Plastics are classified in 6 different types according to their properties. When a plastic doesn't fit in any of those types they are put in Class7 where you can find a lot of different material (food contact and non food contact ones) . Tritan is a transformed co polyester that can't fit in class 1 but for sure it pass all the food contact test, is BPA-Free and doesn't contain any known harmful substance.
I hope this eases any concerns you may have about the suitability of the drinks bottle. At Decathlon we make sure that all of our products are suitable for their intended purpose and does not cause harm to our customers.
