The starter bundle is perfect if you want to incorporate monthly into your period routine seamlessly and save $$$–10% off to be exact! You get 5 pairs of The Boxer Brief (To cut back on the washes, give the favorite bundle a try!)

What is The Boxer Brief?

A comfy, mid-rise boxer brief made from super soft recycled nylon. Our machine-washable boxer brief period underwear is engineered for regular or light flow days, ideal as a standalone solution or reliable backup for heavy flow days. 

(psst.. we've made some really cool updates to the boxer brief like: an extended gusset, a pad shaped gusset to allow more absorbency and comfort, and a reinforced waistband)

Product Details + Fit

This style was made to stretch. Recycled nylon and a forgiving waistband make these perfect for people that experience bloating or heavy cramping–or that just want a lil' extra comfort on their period. They fit true to size, so we recommend ordering your usual size (if you're in between sizes, size up!)

Fabric + Care

  • Shell: 88% Recycled Nylon, 12% Spandex
  • Lining: 100% Cotton
  • Gusset: 75% Bamboo, 25% Polyester

monthly period underwear are machine washable. Wash on cold with like colors. Hang to dry. It's that simple!

Impact

Switching to period underwear helps divert 4 tampons/pads from landfills every day you choose to use them! (not to mention they save you $ in the long term.) Good for you + good for the planet.

Design

We talked to 250+ people with periods before designing our underwear. These folks had heavy flows, light flows, endo, PCOS, gender dysphoria, cramping, and everything in between. Based on these conversations and surveys, here's what we did:

  • Made an ultra stretchy waistband so you don't feel restricted while bloating
  • Full length boxer to allow for gender inclusion
  • Floating gusset so you can wrap a pad inside the underwear in case of emergency or preference
  • Ultra thin pad, so they feel just like your favorite pair of underwear

Trust us, we got your back when it comes to periods. All day comfort informed by real people with real periods. ☁️

    Our boxer brief holds about 25 ml of flow, which is equal to 1 menstrual cup, 3 super tampons, or 5 pads.
