High-Absorption, Low-Effort: The Best Period Underwear for Heavy Flows

September 11, 2023

You wake up on day two of your period, and the floodgates have really opened. You throw your crimson-stained sheets in the laundry, hop in the shower (hoping it will subdue abdominal cramps that are coming in hot), slap some mascara on, and call it a day. 

Except it’s not without its mental aerobics. Six hours of meetings, plus a commute — and, oh god, you just remembered you made happy hour plans. Like a scene out of Good Will Hunting, the math nets out to four tampons, a pair of period underwear, a jar of ibuprofen — oh, and a reusable pad (just in case). 

It’s the kind of minute, largely invisible math people who menstruate do on the daily. While the era of discrete and tidy periods is on its way out, peace of mind remains nice to have. 

There's something about heavy period days that can feel strangely high-alert, leading to constant inspections of your pants (and chairs) for stains and washroom sprints between meetings. 

Whether you have heavy flow days or a generally heavier period, these are the high absorption, low effort products we recommend adding to your period arsenal.

When you need more than just backup protection, it’s time to reach for a pair of Super Leakproof Period Underwear. Whether you spring for a pair of pastel High Rise undies or bright-hued Boyshorts, what matters most is that they effectively absorb blood, sweat, or pee. 

It also helps that they’re machine washable. Dare to never look back after standing up from a chair ever again!
