I bought one of these water bottles on spec at a store clearance for $2 as I wasn't sure about the design. Their shelf price was $26 at the store. I very quickly came to love the bottle and went back to buy more but they were all sold. This does not leak water and is very easy to drink from, even when you are lying down. I use it at gym for this reason and also find that when out walking the shape of the bottle fits snugly under your elbow. It's not bulky and is really a very, very good design by an Australian company.
