lj**** - 5 stars
Reliable beach towel. After swimming, drying off water droplets and wiping with the towel was super quick and convenient. The thin material dries very fast and is easy to carry.
gsal**** - 5 stars
Stayed at a hostel overseas; towel size was large and dries well, reusable three times. Plus, since it’s compressed, it does not take up space and helps prevent breakage of items in luggage.
chee****** - 5 stars
I often use Billy and the larger size is so great. Used well for kids and water play in summer! Repeatedly used and stretched it for cleaning. The best!
tj**** - 5 stars
Bought for waterpark trips with kids. Better quality and size than expected. Shrink-resistant and eco-friendly for the environment.
s2wh***** - 5 stars
Using it for my husband's work trip bag. Shrink-resistant first-class towel! Generously sized even for adult males, thick and no dust shedding.
