Fit Checklist (Fast Way to Avoid Buying the Wrong Straw)

  1. Confirm bottle line: FreeSip Sway (not Flip, Twist, etc.).
  2. Confirm size: 40oz (printed on the bottle or listing).
  3. Measure your old straw if you still have it: length end-to-end and outer diameter.
  4. Check lid interface: the tip/end style must seat correctly in the lid opening.

Why People Choose Metal for the 40oz Sway Replacement Straw

Common buyer reasons

  • Sturdiness: less “flimsy” feel than many generic replacements.
  • Cleaning confidence: rigid interior is easier to brush thoroughly.
  • Durability: designed for long-term reuse.

These are usability/handling reasons (not health claims).

If Official 40oz Replacement Straws Are Out of Stock

Owala sells official replacement straws with a 40oz size option, but availability can vary. When official stock is out, many buyers look for a like-for-like fit alternative.

If you want to compare: see Owala’s replacement straws listing, then match your size and style.

Cleaning: Dishwasher vs Inside-the-Straw Cleaning

Even when a straw is dishwasher-safe, dishwashers often don’t reliably scrub the inside wall of narrow tubes. A straw brush is the practical tool for internal contact cleaning.

Practical method

  • Rinse immediately after use.
  • Use warm water + mild detergent.
  • Run a straw brush through the full length (especially bends).
  • Air-dry completely before storage.
