As advertised! Best thermos I've used yet.


  • Retains heat/cold really long time
  • Doesn't sweat
  • Thermos Very Durable


  • Caps are plastic - can break

I love dual purpose items as we only family camp/ hike some. The rest of the time we're at soccer, or at the beach, or fishing, or ... !

This thermos is a big favorite of mine and it really does work well. I was just commenting on a review about the Starbucks Via Ready Brew coffee and it got me thinking about the Hydro Flask. Whether I'm camping or out at the soccer fields or in a boat somewhere, this thermos keeps my coffee piping hot throughout the day.

And, for the beach, these wide mouth thermos' do really well with a frozen drink of your choice. Margarita, bushwacker, you name it — works great and keeps the beverage frozen. And, they don't sweat.

If there is a weak point, it would be the caps. But, to be honest, I haven't had any issues. They tighten real well with no leaking but if you drop it, it could split. The thermos themselves have a lifetime warranty, though.
