The honest part

A pool day shouldn't depend on the calendar.

Before bettertan

Sitting out the swim, or risking a tampon string in the water.

Counting hours, checking constantly, never quite relaxing.

A beach bag full of single-use everything.

With bettertan

Dive in. The leak-proof barrier holds in and out of the water.

Up to 5 tampons' worth of protection — wear it all afternoon.

Rinse, dry, repeat — one set replaces years of waste.
