GSI Infinity Backpacker Mug

Unimaginably lightweight, insulated mug
Keep your beverage warm on the trail or during a long commute with the Infinity Backpacker Mug.

Our favorite mug, now in the GSI Eco line, leads the way when it comes to materials and manufacturing. Made from BPA-free, non-leaching polypropylene and wrapped in a recycled plastic (rPET) cloth. Holds 17.5 fluid ounces but weighs just 3.5 ounces, making it light enough for even the choosiest, ounce-shaving through-hiker.
