Maintenance Tips for Longevity

Compact bottles are designed for endurance, but proper care ensures they perform for years. Follow these maintenance tips to extend your bottle’s life:

• Rinse thoroughly after each use to remove residue.
• Use a bottle brush for deep cleaning narrow-mouth designs.

• Multi-Day Trekkers: Opt for 24 oz bottles that balance capacity with portability.
