Let's talk about your parts

Last post I mentioned the Intimina Lily Cup Compact - Collapsible Menstrual Cup (size A). FYI there's also a larger size. If you've had a child, for instance, you generally need a larger cup to fit your rearranged anatomy. Don't be left out, moms. There's an INTIMINA Lily Cup Compact -Collapsible Menstrual Cup (Size B) for you too. These cups are non-latex, non staining, and collapsible for packing. I leave the little case home and carry mine in a little cloth bag because I feel like it keeps it drier and airier.

You can also get something like a Diva Cup. It doesn't collapse, but otherwise does the trick. I liked devoting less space in my pack to my cup. Of course, either option is still wildly better than carrying non-reusable supplies.

I don't recommend taking tampons and pads. Carrying them out is kinda gross, you have to store them like you would store food (away from animals!), you have to shop for more in town. They may or may not carry your preferred brand at the dollar general. If you do decide to carry them, or need to carry them, getting something like a Waterproof Reusable Zip Mini Wet Bag makes a lot of sense. At under an ounce, it'll keep your used supplies away from your other gear, and it's opaque for privacy. Nobody else needs to know your business, know what I'm saying?

Non-menstrually, I'm a big fan of pee rags. Nota bene: do NOT pick up fallen bandanas unless you are absolutely sure they are not a pee rag that's fallen off somebody's pack. Even if they aren't pee rags, they have been used to wipe off sweat and snot and are still disgusting. Maybe handle with ziplocks and carry in to the next town to be washed. That said, these are a great solution to carrying and burying or carrying out a whole lot of bath tissue. You still need it for #2, or for menstrual fluid, but plain old urine doesn't need to use up your precious TP resources. They're easily washed in a ziplock with a couple of drops of Campsuds. Note that that size bottle will last you a life time, so I repackage mine into something like 5-100ml Empty Plastic Squeezable Dropper Bottles Eye Liquid Containers. One 10 ml bottle is enough for pretty much a thruhike for me. A lot of people use Dr. Bronner Baby Unscented Liquid Soap but having tried both, I prefer my CampSuds.

I don't use anything special for bath tissue. I get whatever TP the store has, preferably with enough texture to really clean. The single ply stuff that is what you can usually find in individual rolls is definitely not recommended. Yeesh. TP is one of the areas where it makes sense to cough up for better quality. Unfortunately you will almost always have to get a two or four pack to get good toilet paper. Find another hiker to share with. Also, take the cardboard core out of the middle of the roll. That way the roll squishes down and fits better in your pack. You can be all fancy and dispense your TP from the middle of the roll after you do this. I am not fancy. Regardless, be sure to double bag your TP. I put mine in a quart sized freezer bag like Ziploc Quart Freezer Bags. You definitely want the freezer bag version - it will live longer. Then I put that bag inside a gallon size bag like Ziploc Freezer Bag, Gallon Size. With the double layer, you're less likely to suffer the horror of wet toilet paper. Also, having the larger bag means you can open the smaller bag and have a dry space to reach into when it's raining. It is incredibly disappointing to soak your toilet paper with rain while you're trying to get some out of the bag. The larger ziplock also makes a good place to stash other hygiene related items.

Also it is ABSOLUTELY CRITICAL that you keep your booty clean. A microscopic speck back there is enough to create untold misery. I've been using individually packaged Preparation H Totables, Hemorrhoidal Wipes with Witch Hazel for years, but they are not universally available on the trail. Last year I found Sea To Summit Trek and Travel Wilderness Bath Wipes which have been great. You should be able to find them at outfitters for certain. I'm sending myself a pack with my maildrop.

If things get a little tender down there, you're going to need to baby your bottom. I break with tradition and use a product I found a few years ago. The tube is tiny, and it works really well. Mayinglong Musk Hemorrhoids Ointment Cream takes up minimal pack room and lasts approximately forever. I got most of a thruhike out of one tube. If you're using the wipes properly you may not need the stuff, but on those long, hot, sweaty summer days, I think even the salt crystals and heat you generate as your flesh moves across itself is enough to cause misery.
