How do period underwear work?

Do I need to wear a pad or tampon with them?

Nope! Our undies were built to completely replace pads and tampons. They make great backup protection with tampons or menstrual cups, too.

How does the Booster work?

Our undies absorb 4 tampons worth of fluid on their own, but if you need a little extra you can add the optional booster for an extra 4 tampons worth. Just tuck the ends into the slits at either end of the gusset.

How do I wash period underwear?

Our undies were made to fit into your regular laundry routine. Just rinse the gusset in cool water before washing in the machine with your regular laundry. Hang to dry where possible - it saves energy and prolongs the life of your undies.

Peace of mind

Amazing! It is incredible how freeing my period feels thanks to the peace of mind of these products and not having to worry about the toxins of single use products

LOVE these!

These are very well made! I will be ordering more! Except maybe the full boxer. I have an apron belly and the briefs sort of slide down a bit. But I do love the style!

Great

With the insert they absorb a heavy flow. No smell or wet feeling. Super comfortable I would wear them not on my period. Without the insert I would wear at the end of a period, or if I had a lighter one. I am going to buy enough for a week.

Comfy

Wearing comfy underwear is essential for me during my period. I especially love wearing these for overnights by themselves or as back up.

Comfy!

I love the style of this. I was hesitant to buy it at first, because the regular briefs go way past my belly button. Way too high for me. I was worried these would be the same. But I'm pleasantly surprised to say they're not. They sit at the same height as the boy shorts. The band is super comfy and I have full butt coverage so no wedgies. Until they fix the crappy band on the hipsters, I think I'm going to stick to these.
