I adore these water bottles. I have a white one and it is like my 2nd half, i never go anywhere without it. They're super durable and they keep your water nice and cold for 24hrs. They're a little pricey but it's definitely worth it and I've never once regretted owning this bottle. Because they are metal however, they are heavier when full of water so probably not ideal for taking on runs, but not a problem for hikes or going to the gym.
