Period Underwear That’s Changing More Than Just Your Flow

Cold hard truth: traditional period care has a massive waste problem. From single-use pads to plastic-wrapped tampons, every cycle adds to landfills — and that’s just the start.

But in Australia and the US (well other places too, but that's where the team at Fri Period is based so we're a bit biased!), something’s shifting.

People are growing tired of throwaway culture. We’re craving comfort and impact. That’s where Fri Period comes in — and now, with our Good API partnership, every single pair of period underwear you buy plants a tree.

Yep, your undies just got a whole lot more powerful.

Why Period Care Needs a Rethink

Americans and Australians use billions of disposable sanitary products every year. And most of them? They end up in landfill, where they take 500+ years to break down. 

This isn't just bad for the planet — it’s uncomfortable, expensive, and honestly, outdated.

That’s why we created FriPeriod and why more people are switching to period underwear and reusable underpants: a comfy, leak-proof and sustainable way to manage your flow without hurting the Earth. But we knew we could do better. That’s where our mission kicked into high gear.

Meet Fri Period — USA and Australia’s Comfiest Period Undies

If you’ve tried period pants before and felt like you were wearing a nappy, you’re not alone. That’s why we created Fri Period — designed by people who actually get periods.

Our period underwear is:

  • Made with cotton & bamboo
  • Chemical-free, breathable, and seriously soft
  • Features Unique Anti-Leak Tech for maximum leak-proof protection
  • Moisture-wicking, long-lasting, and available in inclusive US and AU sizing 
  • Designed to feel like your go-to everyday undies, but super-powered

We offer styles like our Classic Brief, Boxer Briefs, and Low-Rise Hipster to suit all flows and body types. Oh, and they’re all machine wash safe (just skip the fabric softener, bleach or tumble dryer).

But now, it’s not just about how they feel — it’s about what they do.

A Tree for Every Pair — Our Partnership with Good API

We’re beyond excited to announce our partnership with The Good API — an automation tool that helps purpose-driven brands like us plant trees with every sale.

Here’s the deal:

🌳 For every single pair of period undies you buy, one tree is planted. Automatically.

🌍 It supports reforestation, biodiversity, and climate repair.

📆 Our tree count is fully trackable, transparent, and updates in real-time.

Your reusable period protection just became part of a global solution.

Why This Matters (A Lot)

The climate crisis isn’t slowing down — and neither are we. We believe small, consistent actions create massive ripple effects.

How your new undies make a difference:

  • Reduce waste with every cycle
  • Support ethical manufacturing with certified materials
  • Reforest the planet with Good API’s verified projects
  • Empower menstrual hygiene through sustainable design

This is more than period protection — it’s climate protection.
