This product is amazing! Bought 1 for me and 1 for my husband, mainly for use at work. Very hot, steamy Cafe with no aircon :-( These bottles are big enough to keep us hydrated and cool, without having to constantly refill. The contents stay ice-cold. I add a little lemon to mine and the strainer is fantastic for keeping it where it belongs ... I don't have to strain through my teeth. Just brilliant *****
Love these bottles, we have several different sizes.. get used daily.. this is my second boulder as my first one has been thrashed for several years only ever needed a new sip piece once, until my lovely 13 month old child threw it out the car door & my even more lovely partner ran it over.. has a healthy dent in it which creates a good hand grip & still works great but holds less water, so i used great guilt tripping to get a new one.. ;) best ever drinking vessels ever & saves our environment with less single use plastic.. thank you...

Best waterbottle I have ever bought for my money! Keeps my water cold for 2 days if I have some ice in it!
This is the perfect bottle for hiking and keeps cold all day long! I love the strainer too which keeps me from swallowing ice cubes.
This is the best bottle I have ever used and keeps cold for a really long time.
I love the blue colour!! Keeps my water freezing cold all day. Just how I like it!
The bottle is great but I was more excited about the colour :) :) Ice fresh drinks all day and it looks stylish!
It's honestly amazing how long these bottles can keep cold for. Even when I'm out in the sun working I always have icy cold water! Great product!
