Meet our Essentials Collection, made with our proprietary natural fiber triblend yarn plus the ideal amount of spandex for stay-put comfort all day long. With the power of supersoft (never itchy) alpaca fiber built right in, this breathable bikini brief keeps things dry and odorless. And with the ability to stretch but always keep its shape, this lower-profile pair is unlike any you’ve worn before. Let these natural fibers do the work for you, and you'll forget they're even there.
