To find a Terra System Cord that works well with your frames start by 1) choosing the type of cord you want - adjustable, non-adjustable, endless or long, and then 2) select the type of ends that will best fit your frames and your wearing style (along the temple or on the temple end). You can use our FIT GUIDE to find the ends that fit your eyewear frames and wearing preference.
We also give you one more option - to either purchase a Terra System retainer with one set of ends OR purchase a Terra System retainer with two set of ends to switch out between two different sized frames. Don't forget you can always purchase replacement ends, additional different ends and a FLOAT KIT for your Terra System Cord. With so many options to our modular terra system you really can find the best and most precise retainer for all your eyewear needs.
