GSI Outdoors Infinity Backpacker Mug Your New Favorite Mug If you're going on a hike and want to take a warm beverage with you, you'll want an insulated mug. The GSI Outdoors Infinity Backpacker Mug is made from BPA-free, non-leaching polypropylene and wrapped in a recycled plastic cloth. 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 with graduations for easy measurement holds 17. 5 fluid ounces but weighs just 3. 5 ounces, making it light enough for even the choosiest, ounce-shaving through-hiker.
