This bottle is so pretty and the sparkles got me. It has quickly become my go to bottle. I love that it floats in my pool too. This is the perfect way to stay hydrated everywhere. Literally.

My daughter loves her new water bottle (this is her 2nd one). Her favorite part is the new fonts that are available for the engraving.
- CFCurt F.Verified BuyerRated 5 out of 5 stars2 weeks agoGreat Product
It works Great on my Motorcycle Adventures. I fill it with ice and then by a bottle of my favorite drink and pour that in and put the rest of my bottle in my saddlebag to be poured in when I'm out. The flip open nozzle makes it very easy to drink from as I'm riding down the road. When I stop for gas I usually fill it up again and I'm always amazed at how much ice is still in the bottle even when riding in 96°+ heat with my bottle being Black in color. These bottles are AMAZING & I'd highly recommend them !!!

This one is the perfect size to keep around the house. It helps my water intake improve drastically. Water and ice stay cold for two days. I just keep refilling it.!!!

I ordered the cosmic white for the 21oz size and when it arrived it is beautiful and so far keeps my drink very cold. Will definitely buy again and recommend.
