I was looking for a new bottle to use at work to replace my old one that eventually cracked after several years hard use. One green bottle ticks all the boxes for me, decent size, keeps my drink cool, sustainable durable materials, can go in the dishwasher, so far has proved leakproof, and has a flip up straw for quick grab and go drinking. The little tab on the flip up straw is a little vulnerable, it could possibly do with being made slightly thicker to make it more durable. I also ordered a sloop with mine which is very handy. I would recommend this bottle.
