FIRST Period Shortie Briefs – Tweens & Teens

The FIRST Period Shortie is specially designed for tweens and teens, with sizing tailored for younger, growing bodies. With a little extra coverage on the legs compared to a regular brief, this shortie offers all-day (or night!) comfort, whether it’s your first period or you’re already a pro.

Now featuring even more absorbent padding, these briefs are perfect for medium+ flow days, holding up to 15–20ml(equivalent to 3–4 regular tampons or pads).
Wear them on their own or as backup protection – once you know your flow, you’ll have complete confidence that we’ve got your period covered.
