• DESIGN IN MIND: Comfortable in the hand, this low ball styled cup has a beveled bottom, which provides the perfect shelf for your pinky finger. Unlike crystal whiskey glasses which contain at least 20% lead, the Hydro Flask Rocks are made out of non-toxic BPA-free plastics & 18/8 food-grade stainless steel. This glass was designed after the traditional 10 oz glass rocks cup used by whiskey drinkers for ages, but now improved to prevent your libation from reaching room temperature
  • SLIP-FREE GRIP: Unlike other leading rocks glasses, Hydro Flask's Rocks has a powder coat, which gives you a solid grip. The Powder Coat works with the premium TempShield insulation, which prevents condensation from forming on the outside of the glass, to give you exactly what you want in an amber liquid delivery system.
  • JUST THE RIGHT SIZE: Meets your evening night-cap needs, all while keeping your drink ice cold and fitting comfortably and conveniently in your hand. Alternatively, this 10 oz cup will make for a perfect starter Hydro Flask for your little ones.
  • INSULATION INNOVATION: The double-walled, vacuum insulated TempShield Insulation, the same technology used in all Hydro Flask products, will ensure that your beverage of choice maintains its temperature for many hours to come. Hot drinks up to 6 hours, and cold drinks up to 24 hours.
  • THE PERFECT PRESS-IN LID: The spill-resistant, insulated lid nests within the rim of the cup, avoiding the additional dripping and extra cleaning required from other screw-on glass lids. The lid's Honeycomb Insulation not only keeps your ice from melting, but will act to stop your ice from uncomfortable running into your teeth as you reach the bottom of your glass.

keeps the coffee hot, good for at home, but too small to travel with.

My friend had very specific complains about every travel mug he’d ever encountered, so I set out to find him the perfect mug for Christmas. This one: is 10 ounces, is easy to clean, has no crevices in the lid that could collect junk, has “a good hand-feel”, and is a really lovely shade of red.
