Luna Undies (Lunapanties) Period-Proof Underwear | Full Review

Is it Your Goldilocks Panty?

Luna Undies are made by the same Canada company that brings us cloth Lunapads and the DivaCup menstrual cup. These are the period underwear that used to be known as “Lunapanties.” The company has made a conscious change in branding to be more trans-inclusive and gender diverse. In addition to the name change, the product line has had a little bit of a makeover: It’s been streamlined to have fewer color and style choices. But, they provide just what you need to build a useful period underwear wardrobe. They’ve also introduced a boxer brief style.

Luna Undies have a 60-day conditional return period. Basically, they can’t guarantee a full refund if items have been worn/washed multiple times, and clearance or sale items might be excluded, but everything else should be returnable.

How Luna Undies Work

Luna Undies are mostly designed to be used with Lunapads on heavy period days. They can be worn without the inserts to provide protection against leaks or spotting.

All the Luna Undies styles work the same way:

  1. They have a built-in PUL layer in the gusset that’s leak-proof
  2. A soft organic cotton layer over the PUL
  3. Bands that hold the inserts in place
  4. 4. Soft cotton inserts that you can take out and change as needed

You can double up Lunapads inserts or use no inserts when you wear this period underwear.

Luna Undies Customer Reviews

Most of the reviews for Luna Undies are positive, but some customers wish that this period underwear comes with the winged cloth pads that snap instead of the wingless inserts.

“I have a very heavy flow. These panties saved my week : no leaks, no moisture. Just plain comfort. I can forget about my period and just go through the day like it’s an ordinary day. As a money saver and worry-free product, it’s definitely worth the price. High five, Lunapanties!” – Genevieve M., MenstrualCupReviews.net Review

“Being nonbinary and having a menstrual cycle was something I struggled with a lot, and I was looking for sustainable products as well. I tried a few other similar products before Lunapads but I will never go back!! They’re so comfortable to wear, last almost all day, they’re easy to clean, and they really help me with my dysphoria. Knowing that Lunapads has trans models and uses gender neutral language makes them a step above the rest.” Ryn A., Lunapads.com Review

 

“…initially I was ecstatic with them, but they don’t seem to stand the test of time and look quite worn. They were not true to size and slightly larger than the dimensions I got off underwear I already owned…The elastic to keep the pad in place doesn’t keep it very well and I found they stain easily. They are still an excellent product and I love their pad range and range of patterns and they are perfectly fine.” – Claire, MenstrualCupReviews.net Review

Luna Undies Final Say

Luna Undies are made by a brand that’s been around since 1993. Usually, when a company has been around for that long, they’ve developed good customer service, and that seems to be the case with Luna Undies’ 60-day return policy. If you already own some Lunapads, you can use the wingless styles with this period underwear. The boxer brief style is a very cool addition to the period underwear market and make that time of month more manageable for transgender people. Luna Undies are quality products, and they’re also good choices if you’re looking for menstrual underwear with an absorbency level that you can adjust using cloth pads.
