HYDAWAYCollapsible Tumbler with Lid and Straw - 16 oz I Portable, Insulated Silicone Travel Mug, Hot & Cold Foldable Cup for Coffee, Tea, Camping & Backpacking, Spill Proof Lid & Steel Rim

Good product, very portable and packable. Sleeve stays on fine, instructions clarify to make sure you push it up to the top fold if loose and it's a perfect fit.Only issue is that it is far from spill/leak proof. If Hydaway are looking for suggestions for a V2, I would advise a threaded lid to be able to screw it on for a bit more spill protection.

This is a great portable drinking cup. Sturdy and will last for years. And so it should at the price.

The rubber cup tore after one use rendering it useless so it was returned. It’s flimsy, hard to hold and the sleeve is I’ll fitting. There are better cheaper products available.

This product looks brill however th sleeve is to loose which makes it feel unstable.

Exactly what I was looking for.

Not sturdy enough to hold a drink and collapse with pressure!

Sent back immediately. V disappointing. Thought mountain scene would be printed on mug. Instead it was on a sleeve that was too big and slipped off. Poor advertising and not worth the money.

This cup exceeded my expectations. I wasn't sure if it would work for hot beverages but it does. Easy to hold without burning your self, easy to drink because of the metal rim. All in all, I love it and from now I will not need either plastic nor paper cups. Win win for me and the environment. 👍
