Plus: Our adjustable design means you can confidently rock your BOXER all day long -- just swap out the removable insert as needed to prevent leaks.

Completely replace disposable menstrual products with the comfort and all-day leak-free protection of our new BOXER Brief. Featuring an absorbent 100% organic cotton inner lining, supported by a full-coverage leak-proof panel that extends all the way to the back waistband, Lunapads' BOXER Brief provides all the protection you need in the style that you want.

Wear for complete coverage during your period (no pad or tampon required!), to back up your usual menstrual product routine, or as everyday breathable cotton undies that also protect against unexpected leaks -- the BOXER has you covered no matter what. Rely on the built-in protection alone for lighter days, or customize the absorbency to suit your needs by adding the Insert of your choice and changing throughout the day.

  • A true boxer brief combining the longer leg of a boxer short with the secure fit of a brief
  • Available in sizes XS through 3XL
  • Choose from Regular Cotton (Heather Grey) or Organic Cotton (Black)
  • Both options feature a black inner panel so your undies stay looking fly & stain-free!

Note: If you are near the top of the range for a particular size, or are in-between sizes, please size UP for the best fit.


Additional Info

Additional Info

Features Adjustable Absorbency, Leakproof, Natural Fibres, Organic Fibres
Absorbency Light, Moderate, Heavy
Body Petite, Average, Plus Size
Construction and Performance

Body: 95% Cotton / Organic Cotton and 5% Spandex
Lining: PUL (Polyurethane Laminate) and Organic Cotton fleece
Insert: 100% Organic Cotton fleece.

Worn without an Insert, the BOXER will last approximately as long (per use) as a disposable pad. Inserts can be added for additional absorbency as needed, allowing you to use the same undies for a full day. Changing your Insert as needed is the key to staying comfortable and dry.

How to Use

Inserts can be added as needed by inserting the ends under the bands at each end of the lining. Multiple Inserts may be inserted for increased absorbency, and can be changed throughout the day or night as desired by simply removing and replacing.

Sizes XS - LG include 1 Maxi Insert. XL- 3XL includes 1 Long Insert. Add Maxi Inserts, Long Inserts, or winged Overnight Inserts to increase absorbency. Mini Inserts are not compatible.

Wash and Care

The Lunapads BOXER Brief is fully machine wash & dry safe in any temperature. A quick pre-rinse or soak in cold water prior to washing is recommended, but not necessary, particularly if they are not heavily saturated. Do not soak for longer than 24 hours.

We recommend natural cleaning products such as Nellie’s All Natural Laundry Soda for regular cleaning, and Buncha Farmers Stain Remover to remove any stains. Please avoid the use of chlorine bleach or fabric softeners as this will decrease the performance of the products and is harmful to the environment.

Best. Underwear. Ever!!!!!!Review by RB
Luna panties tend to run small so I always size up. But these boxer briefs are a bit smaller than usual so I had to go an extra size. If you like clingy/snug fit, then one size up is good for you. But if you like it comfy and looser, then an extra size up will be best. Now that I have the size I need, these are the best underwear ever!!! My favorite most comfortable underwear for a few years running was Victoria's Secret before I discovered Lunapads' underwear. I thought they couldn't get any more comfortable, boy I was wrong! These are so comfortable, I don't want to take them off. But unfortunately, panties need to be washed. The only issue I have with them is that they sometimes pinch me in the most uncomfortable of places and I have to make sure my shorts are long enough. Other than that, I totally recommend these!

2 LEGIT 2 QUITReview by JB
These are some of the most comfortable underwear I've even worn. I sized up as suggested and am glad I did because the fit is spot-on. The quality is great and the inside panel provides lots of coverage and protection. The best part - they really work. When I'm wearing them, I feel sexy, confident and secure. Total game changer.

My favourite pair yet!Review by Amy
I've always been a big fan of Lunapads underwear but these boxer briefs are my new favourite! Super comfortable and at the same time I feel sexy AND I feel like they are less likely to leak because of their shape and design. Highly recommend them. (Posted on 1/28/2017)
Can I give this 6 stars!?Review by Kaitlyn
I received my boxers in the black organic cotton just in time for this cycle. They are 100% my new favourite period underwear! AMAZINGLY comfortable! They have full front to back absorbency panel without being too bulky. I tried them under yoga pants and it wasn't visible at all. I recently have been mostly a divacup user but these had such good coverage I was completely comfortable wearing just the boxers with the insert when I went out. Day one I am always very bloated and crampy but did not find the elastic cut into my stomach, which I was very pleased about! I found them to be true to size. I measured my waist and it was on the lower end of the size chart for the XL, but fit perfectly so I would definitely suggest ordering a size up if you measure on the higher number of the chart, and like them to fit looser in the waist.

If you're hesitating, don't!! They are so worth it! I'll be adding another pair (or 2) to my next order! Thank you Lunapads for this fantastic product!! (Posted on 1/10/2017)

Lunapads How-to Guide

Reusable menstrual products are eco-friendly, money-saving, healthy alternatives to disposable pads and tampons. Lunapads will last well over 5 years with recommended use and care! While individual use may vary, we estimate that a single Lunapad replaces 120 disposable pads or tampons.

A Conversation about The DivaCup

There are lots of reasons to switch from tampons to The DivaCup; convenience, comfort, your health, the environment, financial savings & more. This first episode in our new video series shares the personal accounts of a group of DivaCup users, and explores what motivated each woman to try this innovative menstrual solution.

Why Switch to Lunapads?

Roughly 20 billion pads, tampons and applicators are sent to North American landfills annually. Each menstruating person in North America will throw away an estimated 16,800 disposable pads or tampons in their lifetime; products that require hundreds of years to biodegrade. Imagine the difference we could make if we chose to ditch the disposables.
