The first cup of the morning matters more than most. The Ernest Hemingway Fishing Tumbler holds twenty ounces of it, with a stainless steel inner and outer wall and a powder coated finish that takes the knocks of a long day without complaint. Double wall construction keeps coffee hot or water cold for up to six hours, and the snap on, spill resistant thumb slide lid with its rubber gasket means it can ride in a truck cup holder or on a moving deck without incident. A non slip base keeps it where you put it. BPA free, FDA compliant and finished with the EHFC circle banner logo. Hand wash recommended.
