Best soap dish for travel – a soap bag!

Holding my Matador FlatPak soap case still in the package.Soap. I’m not about to travel without it as I travel long-term and I’m guessing you wouldn’t want to either. But any plastic, covered soap dish is one of my one-bag™ travel frustrations. The goo inside as the bar melts. The wasted space inside the soap dish, especially as the soap wears down. The waste of space that the soap dish takes up inside our travel bag.

In 2018, the frustration of traveling with soap came to an end with Matador’s introduction of its FlatPak™ Soap Bar Case and its Dry-Through™ technology.

I marveled at the FlatPack™ from the moment I laid my hands and eyes on it. “This,” I mimicked back to the Matador folks, “is for carrying soap?” Yes, they nodded. “And the soap won’t get gooey?” I asked. “And everything in my bag won’t get all wet and gooey,” I further pressed them. They nodded. A smile started on my face. I rolled the FlatPack™ over in my hands. This is sooo cool! I said, the words breaking through my growing smile. “I have to have one of these!” As soon as it was released, I bought mine. I was definitely trying it during my next travels.

How to carry soap — before 2018

  • Purchase (or borrow) a plastic, covered soap dish
  • Rub off the suds from your wet soap bar
  • Drop your soap into the plastic soap dish — keep the top open until the soap dries or put the soap dish into a plastic bag that zips closed
  • Pack that soap dish
  • Be sure to wipe out the melted soap often

If your soap is dry for sure, you can slip the soap dish in with your clothing but you may want to keep it in a plastic bag. You may want to make sure it’s wedged tightly in a part of your suitcase where it won’t open up and get your other belongings all soapy. A rubber band or ponytail band may help, or may slip off as with this curved soap dish.

How to carry soap when traveling — starting 2018

My Matador-FlatPak soap bag with my partly used soap

  • Purchase (or borrow) a Matador FlatPack™
  • Rub off the suds from your wet soap bar
  • Drop your soap into the FlatPack
  • Roll the top of the FlatPack
  • Buckle the FlatPack, maybe around your bag’s strap for fastest soap drying

No need to worry about your soap’s gunk getting all over your stuff because only soap vapor, as Matador calls it, comes out of the FlatPack.

You can actually put the FlatPack directly into your suitcase/backpack. However, your soap will dry better when you place the case where air can circulate around it. Clip it onto your bag as you move around if it’s still wet when you leave.

For me, soap is no longer even a small frustration. No more large plastic, so more room in my travel bag. And no more heroic measures to keep my beautiful Dove soap from melting.

Here you can see how a full 135-gram bar of soap, a typical size bar, can fit inside well, and how much less space is taken in a bag as the soap is used up. For me, that’s 3-4 weeks. There’s a fold at the bottom to accommodate the width of a new bar and there’s plenty of height to roll the top. When my soap is smaller, I can even pop it into my toiletry case. You may be able to fit it into yours at all times. (Notice I’m careful of where my razor is.)

FlatPack Specifications

  • 11 grams — lighter than a soap dish
  • Fits standard-size soap bars up to  4″ x 2.4 ” x 1.3″

Not clear here: FlatPak is smaller than my plastic case.


  • 3X lighter — compared to most traditional plastic soap bar cases
  • 6X more compact — when compared to most soap bar cases containing 1oz bar of soap
  • Dry-Through™ Technology lets your soap dry through the case
  • Waterproof
  • Flexible Fabric design adapts to the size of the soap bar
  • Hypalon® rolltop closure + YKK® buckle
  • TSA approved*
  • Packs flat in drawer/closet/travel bag when not being used

*I’m glad the FlatPack is TSA approved but as a bar of soap is solid and not a liquid, I don’t see how that’s an issue. I think this is just there because Matador also makes FlatPak™ Toiletry Bottles for liquids. (Looking forward to trying them too.)

My washcloth experiment

I love this soap bag but I’ll save you from a lesson I learned. Shortly after I first started using mine, I was moving from one location to another and I also had my quick dry polyester washing cloth to deal with. I didn’t plan well so although those things dry quite quickly, it was still wet so I put the cloth in alongside my bar of soap. Maybe the one-way membrane in the soap bag would enable my washcloth to dry inside. And then, to complicate things more, I put this in my backpack rather than hanging it outside in the air. The result: Dove goo inside my bag. As you’d likely guess, the web cloth melted my Dove soap. Matador does state that we should put the soap alone into the case.

However, I may try that again, with a somewhat drier cloth, hanging the soap bag outside in the air. But not with my best soap.


Bar Soap vs Body Wash

I’m at a loss as to why some travelers carry liquid body wash. No matter where you use it, it wastes tons of plastic. But for travel, it also becomes a space and spill issue as well as a 100ml/3oz issue. It’s funny that people spend extra money on bar shampoo while carrying a liquid soap. For travel, a bar of soap is always the most convenient way to pack.
