FAQ’s

Why do I need a Waterproof Bag?

Our Waterproof Bags were designed to hold the undies you’re not wearing, whether that’s the fresh pair you’re planning to change into, or the used pair you need to keep hold of until you’re able to wash them. Slimline and discreet, we love them in our handbag or school bag to ensure we’re never caught short.


When should I use a Laundry Bag?

Ideally, every time you wash your Modibodi, you should pop them in a laundry bag. This helps to protect them in the washing machine and will prolong their lifespan. 

Care Guide

Step 1. Wash your Modibodi before wearing them for the first time. This will activate the technology in the gusset for maximum absorbency.

Step 2. Rinse in cold water after use <30° Do not soak, just rinse until the water runs clear!

Step 3. Cold wash (now or later) In a delicates bag is even better!

Step 4. Hang dry. Reuse. Repeat! Go you eco warrior!

Step 5. Hold the fabric softener. This reduces the product’s function!

"Modibodi was the best thing that ever happened to me."

Massive fan!

My first pair and I’m hooked! I use this on my normal flow and surprisingly, I didn’t leak! They feel snug at first but can be gently stretched. I’ve been looking for comfy period pants that didn’t feel bulky or heavy and these seem to be the best! Looking forward to buying more in different colours

Amazing

Bought these for my daughter (15) who was competing in a dance competition. As she hadn't tried tampons, she was worried about bleeding during the performance. She was very pleased with how comfortable they were, not bulky at all. Will definitely be buying more.

Love the idea of these

Love the idea of these, seamfree is exactly what you want for a night out on your period. Unfortunately, 2 years since purchasing, mine are in pretty poor condition and they've stretched quite a bit. I'm going to try a similar style (and be sure to maintain the cold wash) because I swear by Modibodi!

Does the job.

They are reasonably comfortable and work well, but they don't stay put on your bum. Not my favourites compared to the classic bikini.

Great under exercise tights

These undies are great for heavy days where you need to wear tights. I could exercise with confidence knowing that no harsh lines or bulges were showing.
