We absolutely love these tough canteen bottles. We include them in our enrolment kit when children join our nature kindergarten. They are tough, scratch resistant and keep the children's drinks cool all day. We really love the newly designed cap as it is easier for the children to open independently and is less brittle than the previous design. The newly designed matching straws are a great addition, they can be used with or without the bottle. The plastic free packaging is well designed and protects the bottles in transit.
