Iron Flask is the only brand of water bottle my family and I use. They offer every size and style you could want. Also coffee and kids cups as well. I love my cup!

Excellent purchase!
I didn't know that I could love a water bottle as much as I do this one! I purchased the 40 oz. size for me, and the 64 oz. size for my husband and we both are drinking more water than we ever have before. I love that it comes with 3 different lid options, so wherever you are taking it there is the perfect lid to choose from. The colors are so bold and it's really well made, it seems very durable. Another bonus is that it keeps ice a very long time, my husband fills his in the morning and still has ice when he gets home from work. Overall I am very pleased with this purchase, and may even explore the other size options they have for a little variety.

Great Water Bottle
Nicely built and works great. I like that I can toss it around and not have it spill with a 1 year old that was key.
