Pretty & Practical

I first bought the bottle on its own and been loving this size for my cross body bags, but I was getting a little condensation.

Now that problem has completely gone since getting my silicone bottle sleeve, non slippery and no condensation!! Thank you so much 😊

Travel water bottle

It’s an every day put in my bag thing. It’s funny his people comment on it too. It’s the right size and shape to fit in with what ever I’m doing. Now it’s got a cover it’s just sleek and pretty. And it’ll get more attention I’m sure. Love my tall sleek bottle and cover
