FaceSoft Charcoal-Detox Towel ($23)

Did you know that many microfibers are made out of plastics that are harmful to the oceans? When the owners of FaceSoft found that out, they started on a mission to introduce a better sweat towel to the market. Their towels are made of 87 percent "aqua-cotton" and 13 percent infused charcoal rayon. The brand says the charcoal will "will pull toxins and impurities from your skin" and re-activates naturally when exposed to heat from the dryer.

Why we love it: Even if you're not sold on the charcoal claims, this towel is undoubtedly soft and absorbent. I've personally had a FaceSoft towel for about three years, and I'm impressed with how much sweat it absorbs and how it stays smell-free after so many uses and washes.

What's worth noting: Some shoppers have noted lots of pilling on their towels even after first use.
