What our experts say…

I like this bottle SO much. I love the fast flow rate, bumper at the base to protect the bottle and my wooden floorboards from denting when the inevitable happens and it’s dropped while full. I also love the colour, style and handle attached to the lid that enables it to be easily carried when I have my hands full. It was also a very effective insulator and kept my cold water cool for hours and my herbal tea hot for hours too.

This bottle has some great features, like the removable tea strainer and sports cap hidden under the lid. Feels durable and comes with a 100-year warranty! It has a silicone base to protect against drops and knocks. I liked that there is stainless steel on the inside of the plastic lid to stop liquids touching the plastic. Great insulation too. A real multi-purpose bottle.

Lindsay Miles

I love that not only does this bottle look great now, that it will continue to look great too. The paintwork doesn’t scratch or chip and all the pieces in the bottle can be taken apart so that it can be fully deep cleaned. Super high quality finish and so nice to drink from.

Emily Fletcher

This is the ultimate adventure bottle: super-robust with a silicone base to prevent bangs and dings. Most amazingly, the triple insulation keeps your water cold for 90 hours! What I loved most was the tea strainer: fantastic for brewing tea to fuel me through the school/ daycare drop off. I also loved the smooth-edged silicone mouth and the handle for carrying or attaching to my backpack during a hike or bike ride.

I love its versatility. This bottle can have loose leaf tea in it as well, which also educates consumers on reducing waste in other areas. Colour is great. Very sturdy.
