THE DETAILS THAT MATTER
A practical school-day size that balances capacity with kid-friendly carrying.
The silicone straw supports easy drinking without the bite-valve action used on the non-insulated straw bottles.
The front button makes it simple to open, drink and close while on the go.
A built-in handle makes the bottle easy to grab from the school bag or carry between activities.
INSULATED PERFORMANCE
Triple-layer insulation helps keep water cooler through school, sport and longer adventures.
