I received an 18oz Hydro Flask for Christmas this year, and it has changed my life! I filled it with coffee for work at 7:30am this morning, and it is now 11:44am. The coffee is still hot!
This is a great product, and is the first hot beverage container I’ve owned that doesn’t impede coffee flow when drinking and doesn’t leak while I drink from it. It is also small enough that it fits in my car’s cup holder. I highly recommend it.
