The Hydro Flask Skyline Series Standard Mouth Insulated Water Bottle is a modern design evolution on one our customer favorites. Urban Skyline-inspired matte colors are paired with a subdued tonal logo for minimal contrast. This curated series delivers all the performance you expect from Hydro Flask with a fresh style and sleek color scheme. This stainless steel water bottle is large enough to hold water for the day, yet it fits easily into a backpack, gym bag or car cup holder. Staying hydrated is easy when you’ve got this portable thirst-quenching travel buddy. Whether you’re biking to work, heading to the gym during lunch, or hanging with friends after a long day at the office, you can easily take your refreshment with you. Made from durable 18/8 stainless steel, the TempShield double wall vacuum insulation technology will keep cold liquids chilled for up to 24 hours, while hot liquids remain hot for up to 12. The standard mouth opening is large enough to fit most ice cubes, but small enough to sip from on the go. This Hydro Flask metal water bottle is backed by a manufacturer's lifetime warranty.
