GSI Outdoors Infinity Backpacker Mug

This incredibly lightweight, insulated mug will keep your beverages warm on the trail or during a long commute. The insulated sleeve, non-slip footing, and sealable sip through lid keep the contents warm (or cold) and free from spills, trail dust, and critters. A sturdy webbing handle gives a great grip and collapses flush for compact storage in your pack.

The Infinity Mug holds 17.5 fluid ounces but weighs just 3.5 ounces, making it light enough for even the choosiest, ounce-shaving hiker.
