It is a perfect companion for eyeglass wearers: This is a handy case with good protection for those who have eyewear to carry, like prescription sunglasses or reading glasses or any other ones.
You can easily place your glasses that are not in use in the case and clip them to a belt loop, backpack or purse, no matter you are on a serious hiking, travel, or just for daily use.
It keeps everything within easy reach and protected. Always know where they are.
