Absolutly, YES! We created this product to be worn everywhere, all the time, so that you’re always prepared for any situation. Wearing the leather necklaces in the shower is actually better for them in the long run, since it assures that you’ll be keeping the leather clean - just as you are keeping your body. Salt water and sweat can affect the integrity of the ferrocerium rod. As with any metal, they can corrode the ferrocerium rod if left on for an extended period of time. When rinsing off the necklace, make sure to move the ferrocerium rod up and down the leather to completely rinse off any residue from all parts of the necklace.
