Earthwell x Grayl Roaster Loop Insulated Water Bottle

We’ve been huge fans of Grayl ever since discovering the clever Geopress Purifier bottle. The company recently teamed up with Earthwell on the Earthwell x Grayl Roaster Loop Bottle. The design features handsome, laser-etched stencil artwork on the outside. But, it’s more than a pretty face. The bottle’s TempLock double-wall vacuum insulation promises to keep your icy drinks ice-cold for up to 40 hours, beer chilled for up to 16 hours, and hot beverages piping for up to 10 hours. The patented cap dispenses the contents of the bottle at a sip, drink, or chug, and features a thick loop for attaching it wherever is most convenient for you.


  • Available in 25 ounces and four different colors
  • For a larger alternative, upgrade to the Earthwell x Grayl Kewler Bottle for maintaining the desired temperature of up to 32 ounces of your favorite beverage.

Couple this with a long-lasting stainless steel design that keeps drinks cold for 24 hours or hot for 12 hours, and you’ve got a bottle that can work for everyone, especially for the outdoorsy person in your life.

The cap screws on tight, providing a more secure seal than Yeti’s popular tumbler. It comes in six colors, in addition to the classic stainless steel.
