Thongs on your Period? YES! 

Best for: Lightflow days 

A G-String while you are on your Period? Why not? These cuties are Justine’s favorites! Hard to resist those bright colors which will definitely brighten up your day!

Pair them with your favorite fitted dress or yoga pants, and no lines will show! We love that the lining is dark (and has extra layers of padding for ultimate protection!)


Highly absorbent, these soft & breathable. This very popular style is discreet, comfortable, and highly absorbent.

Wear these menstrual undies throughout the day, while working, exercising, or a fancy night out!

How do Period Panties work?

If you’re new to this concept, it may be hard to imagine that you could actually forgo the traditional pads & tampons all together, but, once you make the switch, you’ll never go back! Justine Haines Period Panties & Pads have extra layers of fabric in the gusset, which absorb menstrual blood, urine and or sweat. Easy to care for, they will last you for several years, protect your clothing & sheets, and save you lots of money (the planet too!) For best protection on Heavy day, combine undies with JH Reusable Period Pads, available in various sizes, based on cycle day.


How do I use the underwear?

Wash your Justine Haines undies prior to first use. Wear your panties for 3-6 hours, or as much as 12 hours, depending on the day of your cycle. Pair your JH undies with reusable pad, which you can change every few hours, and you can go 24 hours with the same undies. No more need for disposable products like tampons & pads!


Washing Instructions

  1. Rinse after use
  2. Machine or Hand wash Cold/Warm
  3. Hang to dry (No dryer)
  4. Do not use Bleach/Fabric Softener
  5. Have a Happy Period!

If you have forgotten to rinse after use and the blood has began drying, please follow these steps:

  • Soak used panties in cold or warm water. Do NOT use hot water as this can set the stains.
  • Then add some detergent, preferably a mild & natural brand would be best.
  • You may use stain remover as well, as long as it does not contain bleach.
  • Let the undies/pads soak overnight in the sink or an open container/bucket.
  • Dispose of the water into the toilet and throw the panties/pads into your washing machine.
  • You can use detergent but do NOT use fabric softener as this can reduce the absorbency of the protective padding.
  • Hang and air dry.

Caring for your JH Period Undies will give them a longer life (Which means you save!)



Please check size table carefully before placing your order. We use North American Sizing.
