This is a high-quality product that is that will keep your coffee hot! Excellent size, holds plenty of liquid, the seal is tight. I think the sip cap is easy to use and extends the length of time your liquid stays hot. Outdoor mornings are so much nicer with this ultimate camp mug that you'll probably end up using it everyday like I do. Pretty much the awesomeness you'd expect from Camelbak. Very long time customer and that aint changing anytime soon! Thanks, Camelbak!

Excellent mug!!!!

These mugs are great! They live up to their name. Although they say they keep cold things cold for 6hrs and hot things hot for 4hrs, they last much longer, almost double that. The tops are snug for my kids so they dont pop off. They are not spill proof but do very well if tipped over. Overall great product.

I love the cup

Original product delivered was slightly defective but was replaced quickly at no cost! Much appreciated. The product itself works well. It is sturdy and well designed. Keeps drinks warm for a good amount of time.
