Quick Answer

If you own an Everywhere Bottle and want a splash-resistant option for cold drinks, choose the Everywhere Splash Guard. If you need a replacement lid for a Narrow Mouth Bottle, the Narrow Mouth Lid is your only fit.

Compatibility: Know Your Bottle

The Everywhere Splash Guard is designed specifically for the Everywhere Bottle, while the Narrow Mouth Lid fits only Narrow Mouth Bottles. These accessories are not interchangeable, so check your bottle model before purchasing.

If you own a Narrow Mouth Bottle, the Splash Guard won't fit, and the Narrow Mouth Lid is the correct replacement. Conversely, the Splash Guard is the only splash-prevention option for the Everywhere Bottle.

Care and Usage Differences

Both accessories are dishwasher safe, but hand washing is recommended for the Splash Guard. Neither should be frozen, microwaved, or bleached.

The Splash Guard is not intended for hot beverages, so use it only with cold drinks. The Narrow Mouth Lid does not have this restriction, but it is not designed for hot liquids either—check your bottle's guidelines.

Price and Value

The Everywhere Splash Guard is priced at $2.84 (compare at $4.00), making it an affordable add-on for splash protection. The Narrow Mouth Lid costs $3.57 (compare at $5.95) and is a necessary replacement if you've lost your original lid.

Consider the Splash Guard a low-cost upgrade, while the Narrow Mouth Lid is a functional necessity for bottle owners.

How to Choose: Trade-Offs

  • Everywhere Splash Guard: Adds splash resistance to an Everywhere Bottle for cold drinks. Flexible silicone insert is easy to remove for cleaning or wide-open drinking. Only for Everywhere Bottles, not hot beverages.
  • Narrow Mouth Lid: Replacement lid for Narrow Mouth Bottles. Handled lid only; vessel not included. Fits only Narrow Mouth Bottles. Verify your bottle type before buying.
  • If you have both bottle types: Consider owning both accessories: use the Splash Guard for everyday cold hydration and the Narrow Mouth Lid as a backup or replacement. Check your current lids to avoid duplicates.

Product Facts

  • Everywhere Splash Guard: Flexible silicone insert that pops in or out of the Everywhere Bottle for splash control. This lets you switch between a wide opening and splash-resistant sipping on the same bottle.
