Evolution is a triple-wall vacuum insulated stainless steel drinks bottle. Made by One Green Bottle. It’s perfect for keeping cold drinks cool, for 12 hours, and hot drinks hot, for up to 24 hours. This is the best of the best when it comes to reusable drinks bottles.

We think the 350ml sized bottle is just right for younger children, large enough to hold a good amount of water but small enough for them to carry around when out and about. The slightly textured coating on the bottles not only looks stylish and is more scratch resistant, but also feels great to hold.

The colour coded sports cap tops are intentionally minimal in their design so that there’s less bits to break off. And the caps are completely compatible with the Classic Sports Cap.

The bottle is made from taste-neutral stainless steel, the safest material to drink from.  The cap is BPS/BPA free and is made from recyclable, non-leaching polypropylene with food grade silicone air valve and seal.

Each bottle comes with a colour coordinated, dotty silicone straw, that can be removed if you prefer to tip to drink instead.

This water bottle is purple / lilac in colour (officially called Iris).

If you’re looking for something with a handle we also sell the Sloop loop, a silicone loop that fits around the bottle neck. This is perfect for carrying or attaching to a bag whilst on the go.
