Viv Menstrual Cup Beginner Starter Kit

Period. is highly absorbent underwear, designed to absorb your period, so you don’t have to use tampons or pads. It has a four layer towel technology with a special wicking layer, which means that any period blood is soaked up super fast and you won’t have a ‘wet feeling.’ After you’ve used a pair, you rinse them under the tap, throw them in your laundry, then they’re ready to use again.

Everybody periods differently so it’s tough to be exact. Our average time is about 8 hours on a heavier flow day. Though some customers need to change after 3 to 4 hours, and others can go up to 14 hours (lucky them!). As your period gets lighter, one pair can take you through the day and night (just like regular underwear).

But again, everybody periods and Periods differently, so you need to take one cycle to figure out exactly how often you need to change. Start with a conservative estimate on your heavy days, and check in on your Period underwear after 4 hours. If you still feel good, give it another hour. Keep going until you figure out your limit. Here at Period, we find we need between 3 to 4 pairs on the first two heavy days. And if you leak, please forgive us! Just this once. (Remember how many tampons you have forgiven). Treat the ‘leak’ as a gift and note the hour of your leakage. That is the best indicator of your ‘flow threshold’ how long the underwear will last for you.

How many pairs you need per period is decided by two things. Firstly, do you want to wash any pairs during your period and reuse them during that same period? And what’s your flow threshold? 

Just to give you an idea (but remember everyone periods differently) — here, we tend to use three to four Heavy Period. pairs for Day 1, and the same for Day 2. Then for Day 3, 4 and 5, and sometimes 6 we wear one pair of Medium Period. a day.

Now, if we don’t want to wash any pairs during a period and reuse them, that’s around eight pairs of Heavy Period. and four pairs of Light Period. But if we do wash them and reuse them in the same period, we can cut that down by half. So four pairs of Heavy Period. (wash three before you go to bed on Day 1, and dry overnight for the next day) and two pairs of Medium Period. (wash and dry after use).

Everyone periods differently. When you try your first pair of Period., you’ll need to figure out how many hours they can last for on a heavy day. That’s your flow threshold. You know how you just know with a tampon and pad? And how intuitive it is when you need to change? Well exactly the same thing goes with Period. underwear. On that first try, check in on your underwear every hour or so and see how they’re doing. You’ll know when you’ve hit that threshold, then just remember that time, so you can build your Period. plan around it.

Absolutely. We knew the biggest barrier to people trying Period. underwear would be a fear of leaking, so we purposefully designed Period to be super-super absorbent. Bring it on Day 1 (but easy on the cramps)!

You know how by now with a tampon or pad, you’re just pretty intuitive? Well that’s what happens with Period. underwear. You just feel that moment of change brewing. The padding can start to feel a little heavy or like it’s not absorbing any more. That means it’s reached its limit. 

Just take The Period Bag with a fresh pair of underwear in your bag. When you feel like it’s time to change, go to the bathroom, take off the worn pair, put it in your baggie, wrap it up and put on the new pair. You can rinse and wash the worn pair later at home. 

Yes! And thank you for asking because this is a really important conversation. We’re one of the safest ways you can period. Our underwear is made without PFAS. We rigorously third party test every production, and reject any materials that don’t meet our standards.When we started Period., knowing it was a new category, we were advised to hold ourselves to the highest standard possible in the category. Guess what? We discovered that there weren’t any real high standards — so we created our own. So that you could have the safest flow possible.

And BTW, do you know the FDA has 400 defect warnings about tampons? Yikes.
