If you are a hardKOR thirster, this bottle -- I mean 'Hydration Vessel' is a great addition to your life. You know quality when it's KOR, those guys know how to design a pleasant mass-manufacturable 'Hydration Vessel'. The inner 'Hydration Vessel' is made from a rolled stainless steel sheet, while the outside is made from presumably, the same material, probably machined. It's powder coated for a comfortable grip, and the cap is made from some type of plastic. One thing to watch out for is denting. Sure, it's common for all steel 'Hydration Vessels' but this Vida is more susceptible than the other counterparts. The painted coating chips and since it's white, it gets discoloured rather easily. One thing that's probably bound to happen in the future is uneven discolouration. Since there are two materials, the UV may damage the plastic, causing irregular colour compared to the cap and the body.
Other than that, the shipping was a bit rough. I don't know whether it was caused pre-package or during the transportation. In either case, the bottle was a bit dented. It'll be nice if next time these things were to be shipped with a bubble-wrap or something. Other than that, this is a gem of an item.
