Matador Flat Pack Soap Case Review: Does It Actually Beat a Ziploc Bag?

Introduction

The Matador Flat Pack Soap Case gets a lot of attention in minimalist travel circles. It is a lightweight, waterproof roll-top case that promises to dry your soap out while the bar is sealed inside the bag. It is also considerably more expensive than a Ziploc bag, so the real question is simple: does it actually work well enough to justify carrying it?

Testing Drying Performance: Soap Case vs Plastic Bag

To find out, two identical bars of soap were soaked in a tub of water for about 20 minutes to simulate the length of an average shower. After shaking off the excess water, one bar went straight into a Ziploc bag and the other into the Matador case, with no drying time allowed. Both bags sat overnight for about 12 hours.

That routine, a soak followed by 12 hours sealed in a bag, was repeated five times. The result: the bar in the plastic bag was a hot mess, completely water-logged, squishy, and soft on the outside. The Matador bar was also still wet and soft, with plenty of residue inside the case, but slightly less so. The Matador does a bit better, but the difference is smaller than you might expect.

A second round tested what happens when the bars get about an hour to dry before being sealed. Even with that head start, both cases ended up with somewhat soggy bars by the fifth day, and the Matador was only marginally drier than the Ziploc. If you give the soap enough time to dry almost completely before sealing it, the two options probably perform about the same.

Size and Fit: Which Full-Size Bars Actually Fit

A common criticism is that the case is too small for full-size bars. That comes from the design: the roll-top needs three folds to create a waterproof seal, which limits the usable space inside.

Seven full-size bars were tested, including castile bars and regular soap bars. Most fit easily with room to spare, and Kirk’s Castile, the widest bar tested, still fit fine. Dr. Bronner’s, the largest bar, maxed the bag out with a tight fit on the final roll, but it closed.

The one exception is the Fels-Naptha laundry bar, which is simply too tall. You can push it into the bag, but you cannot get even one roll on the closure, so it will not be waterproof. If you want to carry that bar, you would have to cut a couple of inches off the top.

Communal Shower Practicality

Another fair criticism: the Flat Pack is not great as a soap dish in communal showers. Your two options are taking the bare bar into the shower, which can be unpleasant in a hostel, or bringing the whole case in and washing it off afterward, since it gets covered in soap and thoroughly wet. A draining soap dish has a clear advantage here, because it lets the soap dry before you seal it back up.

Buying Advice

If you move around a lot and rarely have time to let your soap dry before packing, the Matador will keep your bar from turning to mush noticeably better than a plastic bag. If you can spare an hour or more of drying time, the performance gap nearly disappears and a cheap Ziploc does the job almost as well.

The strongest argument for the Matador is durability. After at least two years of regular use, the case still looks almost like new, while plastic bags need to be replaced regularly or their seams repaired to last. It is also slightly heavier and much pricier. Lightweight and inexpensive versus durable and functional is ultimately a personal choice based on your travel style.

Conclusion

The Matador Flat Pack Soap Case is not the magical drying bag some travelers hope for, but it remains a genuinely useful travel product. It dries wet soap somewhat better than a plastic bag, fits nearly every full-size bar tested, and holds up impressively over years of use. Just be aware of its limits: tight fit for oversized bars, awkward handling in communal showers, and a price well above a sandwich bag.
