Oh-so light and yet it’s insulated! The Microlite 710 Straw Top from the folks at GSI is incredibly lightweight at only 11.2 ounces for a 710 ml volume (that’s almost 3 cups!). Though this is a stainless steel bottle, GSI usesĀ Microlite technology, an innovative process that allows the walls to be a mere 2mm thick and yet despite this thinness, your water will remain cold for over 30 hours! Outstanding! The straw top grants one-handed opening, the carry loop makes it easy to transport or attach with a carabiner, and it fits snugly in a car cup holder. Another smart feature is a silicone pad on its base that helps keep it stable. Both the body and the lid are made out of recycled materials, and the company is committed to responsible manufacturing, and stewardship of our environment. Keep it cold without the weight with the eco-friendly GSI Microlite 710 Straw Top!
