Our Essential Bikini is designed to stay put, move with you, and keep you swamp-ass free and funk-free throughout your entire day no matter your adventure.  Our seamless design and comfort waistband eliminate digging and rolling during your hike, ride, climb, workout, or vinyasa.  It’s so comfortable, you’ll forget you’re even wearing it!  

Insider Tip: One of the reasons women love our Bikini is because it’s great in and around water.  It dries in the blink of an eye!

Tell me more about the fit

Our innerwear is meant to fit snug on the body, if you prefer a looser fit, then we recommend sizing up.  If it feels just a little tight and you aren't sure if the next size up would be better, then we recommend wearing/washing it 3-5 times to see if it breaks in to your liking before exchanging it for another size.

Will it stretch out?

Not really.  Our innerwear does give with wear, but only to mold to your body.

Insider Tip: One of the reasons women love our Bikini is because it’s great in and around water.  It dries in the blink of an eye!

Our Essential Bikini features a low-rise and four-way knit stretch that fits snug around your hips.  Constructed using seamless knitting technology so the seams lie flat against your body without chafing.  

Performance Innerwear is designed to hug your body.  If you prefer a less compressed fit, or are in-between sizes, we recommend sizing up.  See size guide for more information.

Machine wash cold with like colors and mild eco-friendly detergent. Do not use bleach or fabric softener.  Always wash black and dark colors separately. No washing machine?  Simply hand wash with a mild soap or shampoo in the sink, or in the shower, and hang to dry. Do not dry clean.
 
A GLDNspun knit blend of 81% extra fine Merino wool, 12% nylon, 7% spandex.

Our Merino wool is sourced from sheep raised in Australia.  Our yarn is engineered and spun by Sudwolle Group in Europe. Our factory is located in Istanbul, Turkey.  

Each individual piece is knit seamlessly on Santoni machines as a panel in its natural un-dyed color.  Then, the panels are garment dyed in small batches.  Next, each panel is hand-cut to its final shape.  Finally, the cut pieces are sewn, and hand finished as needed.  Each garment is unique, so no two garments are exactly alike. We are very proud of our craft, slow manufacturing process.

Super stretchy and awesome!

I have the hipsters in medium and bought the bikinis in small because there were no mediums left. They looked TINY taking them out of the package but they are super stretchy and comfy and ride down less than my mediums. I’m so happy I bought 3 pairs for the bundle deal to add to my Branwyn collection - also have 2 bralettes that are really all I wear. I’m definitely a fan of this company and I’ll be back for more!

Love the bottoms!

These are so comfortable! I’ve been searching for innerwear that is suitable for a petite figure but has enough stretch since I am pregnant. The cut is working perfectly with my changing body and keeps me comfortable all day. I really appreciate how the seams are not bulky! The investment was definitely worth it!

Like them a lot

I really like these, I just prefer the Hipster for more coverage. The quality seems great and I like the material.
