The GSI Infinity Backpack Mug is an insulated camp mug made from BPA-free, non-leaching polypropylene wrapped in a recycled plastic (rPET) cloth. It holds 17.5 fluid ounces yet weighs just 3.5 ounces, making it light enough for even the choosiest, ounce-shaving through-hiker.
Insulated sleeve, non-slip footing, and sealable sip-through lid keep contents warm (or cold) and free from spills, trail dust, and critters
Sturdy webbing handle gives a great grip and collapses flush for compact storage in your pack
