Engineered for your commute, this low-profile bottle is one-third lighter than our standard stainless steel bottles. The secret is Stanley’s AeroLight featherweight technology that doesn’t compromise on durability or thermal performance. Your water will stay cold from the time you leave home until well after quitting time. The drink-through lid locks tight for leakproof carrying in your bag or pack.
