    Finally a Place to Store All those Soap Pieces! Self-Lathering, Exfoliating, Good Quality, Love it!
    Style: Sport
    These soap saver pouches are a really nice upgrade to using regular bar soap and a loofah or washcloth. I love that I can just drop in a full bar, along with all those tiny leftover pieces, and still get great use out of them, while also getting a nice scrub that has a good exfoliating texture without feeling too harsh. It's a medium-like "grit" so just be aware, and both sides feel equally scrubby, and the inner pad material helps the soap foam up easily when you rub it together, making it feel efficient. The three-pack with different colors is convenient for multiple bathrooms or spares, and the little inner loop lets you cinch the opening so smaller soap bits don’t fall out. It does need to be hung to dry since it holds onto moisture, and your soap may go a bit faster because of that constant self-lathering as you use it, but it’s not too bad, and a fair trade-off for how easy and effective it is. All in all, these are well-designed and genuinely useful. Definitely recommended!

    Exfoliating, durable, helps bars of soap last much longer.
    Style: Sport
    Am very happy with the convenience and longevity of this product. In addition the exfoliating properties they really do help make my bars of (sometimes quit expensive) soap in the shower last a lot longer - as much as 3 to 5 times as long. I simply hang it up or place on a shower caddy after rinsing the excess suds off and no more soft, soggy bars of leftover soap laying around. Having tried many different versions of these and I find this style is the easiest to get to properly hold onto any odd shaped or larger bars of soap without the soap accidentally popping out in the shower during use. They also seem to outlast many of the other soap savers. They don’t unexpectedly start unraveling after just a few uses like some of the bath poufs tend to do.

    Really good, however, a drawstring to keep the soap inside would be amazing
    Style: Sport
    I bought these sport soap saver bags and I really enjoy them. I exfoliate with loofah all the time so I did not find the grit of this soap saver bag too abrasive. I found it perfect. I washed and lathered all my parts no problem. I had a half gone bar of soap I put inside upon receiving these bags, and the lather was amazing. The soap did move around the smallest little bit because it was smaller. I assume with a brand new bar soap It’s much easier to use. But that happens with all of these same design products. A drawstring at the end of the soap saver bag would make this five stars all day. I would definitely buy these again based on the quality and exfoliation level.
