If you use those big 3- or 5-gallon water jugs, you know how easy it is to lose or crack the caps.

These Calvana replacements are made of flexible, durable silicone, so they're reusable and won't break like cheap plastic ones.

They fit 55mm openings – standard for most snap-top water bottles.

Just check your bottle opening before you buy to make sure it's a match.

The silicone creates a tight, leak-resistant seal that keeps water from spilling during storage or transport – whether you're hauling jugs to the office, the campsite, or just across the kitchen.

They've got an upgraded inner cap design that prevents the center plug from falling into the bottle, which is a super common annoyance with other caps.

Soft and easy to install or remove – no tools needed.

This 6-pack gives you plenty of spares or lets you cap multiple jugs at once.
