Next level hydration. The 36-ounce IceFlow Flip Straw 2.0 Bottle has premium AeroLight™ technology that makes it 33% lighter than standard stainless-steel bottles. Featherweight spun-steel insulation keeps your water ice-cold for hours. The folding handle makes this the perfect grab and go for a hot yoga class.  The Flip Straw 2.0 lid has a larger drink opening and a built-in straw, so you can hydrate faster. Flip to sip, snap it shut and slip the bottle into your bag. You can even pop off the new spout for a deeper clean.   Sustainability   To help you live a sustainable lifestyle, the IceFlow™ Flip Straw 2.0 Bottle is made from 90% recycled stainless steel. Durable stainless-steel designs have made Stanley a leader in reusability for over a hundred years. We’ll continue to build on that legacy by committing to use recycled stainless steel in at least 50% of our products by 2025.
