In addition to the java press we also tested the GSI Outdoors Infinity Backpacking Mug.

Testing a simple backpacking mug while simultaneously testing a fancy java press proved challenging. Naturally, we fell in love with the java press over the mug.

However, this mug held 2 more ounces than the java press and sometimes those extra two ounces of caffeine are a complete necessity.

Like the java press, the backpacking mug is made out of shatter-resistant BPA free polypropylene, only it is dishwasher safe because it doesn’t have a filter like the press. The mug also comes with a removable insulated sleeve covered with nylon webbing.

The infinity mug is tough, lightweight, durable and easy to drink from. It keeps beverages just as warm as any other travel mug, and we couldn’t get it to leak no matter how hard we tried.

Because it’s wide and shallow rather than tall and narrow it can easily double as a bowl at the campsite.

  • This mug weighs 3.5 ounces; when I first picked it up, I was shocked at how little it weighs
  • Some advantages of the infinity mug are that it will not absorb food odors, it's stain-resistant and it works great with hot and cold beverages and foods
  • I like that it can serve double-duty as a mug and bowl, unless I want to drink tea while eating oatmeal
  • The infinity mug retails for $9.95. Once again, that’s a great price for a travel style mug of its quality


  • The handle feels flimsy. It didn’t break while we were testing it, but I expected it to
