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.

The Essential Bikini is designed to stay put and move with you throughout your entire day.  Featuring an elastic-free waistband that eliminates digging and rolling, she’s so comfortable that you’ll forget you’re even wearing it! 

A low-rise and four-way knit stretch bikini that fits snug around your hips.  Constructed using seamless knitting technology so that the seams lie flat against your body.  All innerwear is meant to hug the body.  If you prefer a less compressed fit or are in between sizes we recommend sizing up.  See size guide for more information.

GLDNspun Merino Blend (81% merino wool, 12% nylon, 7% spandex) that's naturally moisture-wicking and odor resistant.

Machine washable and dryable, however we like to wash our innerwear in cold water with like colors, no bleach or fabric softener, and hang them to dry to preserve their longevity.  On the road or in the wild?  Hand wash in the shower or in fresh spring water and hang to dry.

We source our Merino wool from ethically raised sheep in Australia.  Our yarn is engineered and spun by Sudwolle in Germany after which it is sent to Istanbul, Turkey where it is seamlessly knit, dyed, constructed prior to being shipped to HQ in Portland, Oregon.

Highly Recommend

I highly, highly recommend Branwyn for their excellent customer service, ethics, and outstanding product. I had issues with the sizing and they sent me the correct size no problem. I now have two pairs of the bikini and one of their bralette. In my quest for good hiking underwear, I have tried on pretty much ALL of the brands. Everything else rode up immediately within a couple steps. I thought I would have to relegate myself to thongs to prevent giant wedgies given by all other underwear...until Branwyn came along! Literally the ONLY Merino underwear that truly doesn't ride up, is comfortable, and keeps me dry even hiking in hot, humid Florida summers. My measurements are 28" waist, 42" glutes and I settled on the Large bikini (the medium I tried did not end up loosening up enough to be comfortable). I definitely recommend sizing up if you're in between sizes or have larger glutes. The cut of the bikini is very conservative and does show some panty lines, and the bralette has no shaping/shows nipples when it's cold. This doesn't matter much because I got them for hiking, but if they made a Brazilian/cheeky cut underwear or a bralette with some shaping to it I would literally immediately replace my entire drawer (different colors like Blue would be a cherry on top, pretty please!). If you're unsure because of the price...they're worth it for well made Merino from an ethical company.
