The biggest Micro Hydro

The removable FlexClip bottle strap lets it slip easily onto a bag or waist, double-wall vacuum insulation holds 10 hours hot and 24 hours cold, and the tiny size still sits easily in the palm of a hand. Backed by Hydro Flask's iconic insulation, leakproof technology, and lifetime warranty.
