Size Guide

WHAT IS PYRKIÄ? Pyrkiä (pronounced pir-kē-ə) is all-activity, all-weather, waterproof, medical-grade silicone jewelry.

WHAT MAKES PYRKIÄ BRACELETS UNIQUE? Pyrkiä's unique, triple-wrap bracelets clasp easily with twelve tiny-but-strong embedded earth magnets. Two safety bands are included with each bracelet to keep it safely in place during the most rigorous activity.  

FINDING THE BEST SIZE FOR YOU.  To be sure you are ordering the correct size, take a ribbon or string and wrap it around your wrist.  Measure the ribbon/string on a ruler and order the size closest to that measurement.  Even a half of an inch will make a difference in which size will be the best fit for you, so be sure to measure.  

HOW ARE YOU GOING TO ENJOY YOUR PYRKIÄ BRACELET? Yoga, running, biking, weight lifting, swimming, dancing, rock climbing, snowboarding, kayaking, surfing, sailing, paddle boarding… the list is endless. And for those of us who have to sneak some work in between all that fun, Pyrkiä bracelets are a perfect fit for any field! Health and medical, law enforcement, construction, military, installation and repair, science, or the arts.

LIFE CAN GET MESSY. So can your Pyrkiä bracelet – but they clean up easily with a little soap and water. Now don’t you wish everything in life was that simple?

CAN'T WE ALL USE A LITTLE MORE COMFORT IN OUR LIFE? Your unique bracelet will add comfort to your style (and a little style to your comfort). You'll barely feel that it's on! 

ANY WAY YOU STACK IT, IT'S SURE TO ADD STYLE!  This specialized bracelet is made to look fantastic on its own, but for added style here are some additional ways to stack it:

  • try it with another Pyrkiä bracelet
  • put it next to an activity tracker (Fitbit, Garmin, etc.)
  • pair it with a smart watch (Apple Watch, etc.)
  • load it up with any of your favorite bracelets or other jewelry

We took this definition to heart when we adopted the phrase “Strive for Progress Not Perfection” as our company motto. This motto is inscribed on the inside of every Pyrkiä bracelet.

A wide selection available for men, women, boys and girls!
