Our Essential Thong has a "forget it's even on" level of comfort and a low-profile.  It will keep you swamp-ass free and funk-free, and fresh and dry all day long.  Our seamless design and comfort waistband eliminates digging and rolling during your hike, ride, climb, workout, or vinyasa.  It’s the perfect “barely-there” solution for your toughest of workouts, and longest adventures! 

Insider Tip: One of the reasons women love our Thong is because it is virtually invisible under workout gear including leggings and base layers.

SIZE GUIDE

All knitwear has some stretch, so you might be able to wear two different sizes.  We recommend going with your usual size. 

**Our current inventory of Light Nude, Warm Nude and Dark Nude are running small in the back rise.  For a larger leg opening we recommend going up one size.**

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.

What sizes are the models wearing?

Emma is wearing the Black and Warm Nude thong in a Small, Galen is wearing the Light Nude thong in a Medium, Riley is wearing the Light Nude thong in an X-Large, and Bri is wearing the Dark Nude thong in a Medium.

It’s a low-rise, four-way knit stretch T-back thong with full frontal coverage that fits snug around the hips and is meant to hug your body.  

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.

Who knew I could love wearing thongs!

I've had a mixed relationship with thongs for the last 20 years. They usually end up at the back of the underwear drawer unless my husband starts complaining about my boring underwear. (I'm a comfort rules kinda gal). Thought I would give the wool thongs a try and boy am I glad I did! I work outside all day in the heat and can wear these without chafing or any issues at all - I barely even notice they are there. I now pick these over my regular panties. Thank you for making the perfect thong! (I'm normally a size 4 and ordered medium in black.)
