I got this to replace my other water bottle. I use it in gym or on bike. The insulated layer keeps the water cool during work out for over one hour. It is much more convenient to just squeeze instead of opening the lid. and it doesn't taste plastic after I wash it several time.
i have this and the larger size on my bike. the insulation unfortunately doesn't make much of a difference on a hot day. i will suggest you freeze your camelbak before you take a long ride.this bottle is awesome. nothing competes with the spout.always works.
