This bottle boasts 18/8 stainless steel, with a vacuum sealed, double wall. Bottle is bps free, and holds 21 oz. I like that this bottle is large enough to hold a good amount of both cold and hot liquids, but still small enough to take hiking or slid into your bikes bottle holder. The outside has an easy grip texture, much better than the smooth textured counter parts. I was able to fill this up before bed, and it was still really cold this morning (around 9 hours later), with large chunks of ice. The mouth of the bottle is large enough for any size ice cubes, as well as easy to drink from. It’s not heavy in weight, but you can tell its heavy in top notch material. This bottle is a great assets for biking, hiking, or just hanging around the house.
