When Yeti first introduced their tumblers I said I would not own one for two reasons. One, they cost too much and two, I prefer a handle on mine. Makes it easier to grab when I am driving the car or boat.

The first issue resolved itself when I got one as a birthday gift. I set about to resolve the second issue and thought I would share in case any of you might find it useful.

I found handles for Tervis tumblers and the 16 oz one was $6 so I bought one. My Yeti is a 20 oz so the handle only would go up about half way, which worked but was awkward. So, using a bit of engineering theory, I put the handle in a pot of hot water and the Yeti in the fridge for 10 min. Took out the Yeti and rubbed dish soap around the top and slid the handle to a perfect spot.
Works like a charm.

Funny thing reading the comments on the Tervis website they state it only fits Tervis products. Marketing I guess.

And by the way, it is amazing how long it keeps things hot or cold. I have set mine in the kitchen at night with ice in it and the next morning most of the ice was still frozen.
