  • Kotex discontinued the pads I use suddenly, feeling hopeless
    I think you should look into period underwear. Its more expensive than pads, but its reusable for years and saves money. Ranges from about $20-$30. thinx.com has a teen section with smaller sizes and a variety of styles. Source: about 1 year ago
  • Refugees or bugging out
    I have been advocation menstrual cups to those who are still having their cycles when doing through hikes or just camping for a few days. I have never heard of the flex disk before and thanks for recommending it. I use a p-style when out as it is what "fits" me best. Also, look into thinx.com for absorbent menstrual panties which I bought for my niece. That company also makes absorbent panties for bladder... Source: over 1 year ago
  • How do you deal with your period when traveling? especially if you are in a fairly remote area or in an area with questionable toilet facilities
    I have "period underwear". Thinx brand specifically. They are super absorbent, attractive, and easy to clean. They aren't thick, so you can wear them like normal underwear too, and come in all the needs from thongs to briefs. I like to pack half and half - regular underwear vs period type. When you can't access washing machines, they are as easy to wash in the shower, or however you clean your underwear... Source: over 2 years ago
  • Looking for product recommendation
    Here is what I use most often. In the daytime, I usually wear absorbent undies with a pad. My favorites are Thinx (shethinx.com) and Knix (knixteen.com) because they absorb a lot quickly and they look a little like normal undies. I usually use a prevail pad along with them for extra protection and because it will absorb fluids that tend to leak when I'm sitting down. Tena and Prevail are my go-to pads.
