About RED by Modibodi

So what is RED and how does it work?
RED is a brand built off remarkably clever technology which makes underwear magically absorbent, meaning you can #ditchthedisposables, get rid of tampons and pads and rely solely on your RED undies for your period.
Is RED Period-proof underwear & swimwear GST Free?
From the 1st January 2019, All leak-proof underwear, activewear and swimwear including GST-free for Australian customers. GST still applies to accessories.
Do you need to wear any pads or tampons when wearing RED Period Proof underwear?
RED underwear is designed to cater for a moderate/heavy flow, so if that sounds like your monthly visitor then you should be fine to go without any pads or tampons! However, if you have a monster month, you may want to doubly protect yourself with a tampon or menstrual cup to wear with your RED undies.
How do you use RED period proof underwear?
You just wear the RED period proof underwear like you would your regular undies, but without the hassle of having to use a tampon, menstrual cup or pad. Pop your RED underwear on in the morning and go about your day as if you didn’t even have your period.

When you’re getting ready for bed, take off your RED undies and rinse them in the sink with cold water until the water runs clear. Give them a cheeky squeeze to drain excess water before popping them in the washing basket ready for the next load. Once they’ve been through the washing machine, pin them up on the washing line and after they’ve had enough sun to dry them, you can wear again! In the meantime, while they’re going through the washing process, pop on another pair of REDs to wear overnight.
How do you use RED period proof swimwear?
RED swimmers offer you that comforting level of protection when you’re hitting the beach while on your period. Using our patent pending Modifier Swim Technology that is similar to what’s found in the RED undies, the RED swimmers will absorb any period leaks while you’re having fun in the sun. The absorbency on the RED swimwear is light to moderate. A fun fact is you don’t actually bleed when you’re in the water, so you only need leak protection for when you’re on the sand.
How much fluid does RED period proof underwear hold?
All RED period proof underwear holds 15 to 20 mls of liquid, which works out to be 2 teaspoons or 1.5-2 regular tampons
Will RED period proof underwear smell or feel wet?
Definitely not. The clever technology in the undie gusset absorbs liquid (to keep you dry) and locks in odour, so you don’t have to worry about that ‘period smell’ getting out.

Reviewers of RED have said that it’s a similar sensation to wearing a pad, but without the ‘soggy’ or ‘smelly’ side effects that you often get with a pad with the added bonus of feeling amazingly free and comfortable, and you are saving the planet at the same time.
Is it icky to clean RED?
Hell no! Firstly, you should never be grossed out by your own period blood, because it’s the most natural, normal thing in the world. Secondly, you just need to rinse them in the sink/shower and let the running water do the hard work for you.
Is RED period proof underwear just for teens?
RED is designed specifically with growing bodies in mind, meaning the sizing is listed in ‘Youth’ sizes and the cut and colours cater more to a teen audience. However, nothing is stopping non-teens from joining the #REDsquad too!

If you’re looking for a similar period-proof product, but in ‘Ladies’ sizes and with varying absorbency levels, then take a gander at Modibodi here.
I’m a student, can I get a discount on RED?
You certainly can! By signing up as a RED VIP and being a member of Student Beans, you can get 10% off RED.

You can also get a discount (without being a student) through purchasing a bundle pack. Bundle packs have up to 7 pairs of undies in them, all selling at a discounted price, meaning you can save a heap while also making sure you’re fully equipped for your next period!
Will I need to change RED throughout the day?
You should be fine to wear RED for a whole day before changing into a fresh pair to sleep in. If your flow is heavy, you may need to change throughout the day.
How many pairs of RED will I need?
We would recommend buying at least one pair for each day of your period. So if you have a 5 day period, then 5 pairs would be ideal. You might want to grab a few extras if you do a semi-infrequent laundry load and you want to wear your RED undies to sleep in.
