Review: Great bottle, but 900ml isn't for everyday carry - This is an excellent bottle. The colour is exquisite and it can keep water at the right temperature. I believe the build quality is durable and it certainly doesn't leak at all. I bought the 900ml one, which is already quite heavy even when empty and weighs around double when full. It is possible that the 500ml and 750ml might be better for everyday carry, though I wouldn't recommend the latter for strenuous outdoor activities such as hiking.
