You know that feeling. The one where you check your chair every time you stand up. It is time to stop worrying. Period underwear is here to change your life. In this guide, you will learn how to choose menstrual underwear that actually works for you. No leaks. No stress. Just you being you. Let's find your new favorite pair.

Choosing the right protection is about your comfort. You deserve to feel dry and safe. Whether you are at work, at the gym, or sleeping, your period should not hold you back. We created this guide to make the switch easy. You will learn about technology, absorbency, and how to find your perfect fit.

What Are Menstrual Underwear?

They look like your favorite panties. They feel like them too. But they have a secret. They absorb your period so you do not have to use pads or tampons. Reusable period underwear is better for your body and the planet. It is the simple switch you have been waiting for. These are not bulky diapers. They are smart clothes for smart women.

Many women use them alone. Others use them as a backup for a menstrual cup. If you are curious about cups, you can see how the LUNACUP works with your body. But for many, LUNA+ panties are all they need. They are designed to be your hero every single month.

How Do LUNA+ Menstrual Underwear Work?

We spent years making the perfect pair. We wanted something thin but powerful. The result is our LUNA+ collection. It uses 4th Gen bonding technology. This means no thick seams and no bulk. Just smooth, invisible protection.

Triple-Layer Technology

Every pair of LUNA+ has three special layers. They work together to keep you safe. First, there is the Dry-Touch layer. It pulls liquid away from your skin instantly. You stay dry and fresh. Second is the absorbent core. This layer is thin as a credit card but holds a lot of liquid. Third is the leak-proof barrier. This layer ensures it won't leak. Not even sideways.

Our materials are antibacterial without using silver. This is better for your sensitive areas. We use Silk Touch material. It is soft against your skin and stays that way. These panties are built to last 2 to 3 years with proper care.

Absorbency Levels

Not every day of your period is the same. Your underwear should match your flow. We measure absorbency in milliliters. Most of our LUNA+ styles have a 20ml+ capacity. That is more than a standard night pad. Some styles hold even more for your heaviest days.

• Light Flow: Perfect for the start or end of your cycle.
• Medium Flow: Great for everyday wear during your period.
• Heavy Flow: Maximum protection for heavy days or overnight.

How to Choose the Right Pair

Finding the right pair is easy when you know what to look for. Think about your routine. Think about your body. You are the hero here. The underwear is just your sidekick. Here is how to make the best choice for your needs.

By Flow Level

Check your current habits. How often do you change your pad or tampon? If you change every 2-3 hours, you have a heavy flow. You should choose our high-absorbency LUNA+ models. If you only change a few times a day, medium absorbency is perfect. Always have a mix of styles in your drawer. This way, you are ready for any day of the month.

If you are worried about leaks while swimming, we have a solution for that too. Our LUNA Swimwear handles your cycle while you enjoy the water. It uses the same great technology to keep you safe in the pool or at the beach.

By Activity

What does your day look like? If you are sitting in an office, comfort is key. Look for our seamless styles. They disappear under leggings or tight skirts. If you are active, you need a pair that stays in place. Our sportier cuts are designed to move with you. They won't shift or bunch up while you run or dance.

For sleeping, choose a high-waisted style. These offer more coverage in the back. This is important when you are lying down. You can sleep through the night without checking the sheets in the morning. Explore the full range of LUNA+ to see all the different cuts.

By Size

Size matters for protection. If the leg holes are too loose, you might leak. If they are too tight, you will be uncomfortable. Do not just guess your size. Use a measuring tape. Measure your hips at the widest point. Compare this to our size chart. If you are between sizes, we usually suggest the larger one for comfort. Remember, we offer a 40-day try guarantee. If the fit is not right, we will help you out. No questions asked.

LUNA+ vs Disposables — Cost Comparison Table

Many women worry about the price of menstrual panties. But think about the long term. You buy pads every single month. That money disappears. With our Fair Price strategy, we make it affordable. We do not spend money on big ads. We gave the ad money to you. This means you get premium quality for a fair price.

When you choose our Smart Choice: 3+1 FREE promotion, the value is even better. You get enough pairs for your whole cycle and save money at the same time. It is the smartest way to shop for reusable period underwear.

Care & Washing Guide

Taking care of your LUNA+ is simple. You do not need special chemicals. Just follow these easy steps to keep them working for years. Proper care ensures the Silk Touch material stays soft and the absorbent core stays powerful.

1. Rinse: After wearing, rinse them in cold water until the water runs clear.
2. Wash: Put them in the washing machine. Use a cold or 30-degree cycle. Do not use fabric softener. Softener can coat the fibers and stop them from absorbing.
3. Dry: Hang them up to air dry. Do not use a tumble dryer or put them on a hot radiator. Heat can damage the leak-proof layer.

That is it. No fuss. No stress. They will be ready for your next cycle. Because they last so long, you are doing something great for yourself and the earth. If you use a cup like the LUNACUP, you can wash them both together. It is all part of a simple, modern routine.

We believe in our products. That is why we offer a 40-day try guarantee. You can test them at home. If you do not love them, we will take them back. We want you to be 100% happy with your choice. This is the LunaCare way.

FAQ

How many pairs do I need? Most women find that 4 to 6 pairs is the perfect amount. This allows you to wear one, have one in the wash, and one drying. Our 3+1 FREE deal is a great way to start your collection.

Can I wear them all day? Yes. Most of our LUNA+ styles can be worn for up to 12 hours. If you have a very heavy flow, you might want to change them sooner. You will quickly learn what works for your body.

Do they smell? No. We use antibacterial materials that prevent odor. Because the fabric is breathable, you stay fresh all day long. This is a big upgrade from plastic pads.

Are they bulky under clothes? Not at all. Our 4th Gen bonding makes them thin as a credit card. You can even wear them under tight gym leggings without anyone knowing.

Can I use them for sports? Absolutely. They are designed to stay in place. Whether you are running or doing yoga, they move with you. They are much more secure than a pad that might shift.

Do I need to use a pad with them? No. LUNA+ is designed to replace pads and tampons entirely. However, some women like to use them as a backup for a cup on their heaviest days.

How long do they last? With proper care (no heat, no softener), your LUNA+ panties will last for 2 to 3 years. This makes them a very smart investment.

What if they leak? Our technology is designed so they won't leak. Not even sideways. Make sure you have the right size and absorbency for your flow level for the best results.

Finding the right protection changes everything. No more worrying about stains. No more rushing to the bathroom. Just comfort and confidence every day of the month. You are ready to make the switch.
