This has got to be one of my favorite purchases of the last couple years. It's 22oz. from Highwave. I paid about $25 for it via Amazon. It's wide base makes it stable everywhere, even the dash of my truck. It's kept coffee cold in the middle of winter for 5 hours +. It's got a sip anywhere lid, and with its optional second lid, it becomes leakproof. The big handle lets me grab it with gloves, and easy to clip to my bag. This sucker is bombproof.
