The unisex adjustable glasses cord by Quiksilver in classic black is the ultimate accessory for action and water sports enthusiasts. 

It is specially designed for use at sea, on boats, and in watersports (such as surfing, SUP, kayaking, and sailing). Its sturdy construction ensures that your glasses will remain perfectly stable and secure on your face, even under the most demanding conditions with strong waves or high speed.

Quiksilver combines high protection with comfort, using a material that is exceptionally soft to the touch, which does not irritate the neck, while at the same time offering great resistance against wear from saltwater and solar radiation. 

Thanks to the smart design of its ends, this cord offers universal compatibility and fits all types of glasses on the market, from thin metal optical frames to wide acetate sporty sunglasses frames.

The ability to adjust the length is key to never losing your glasses during intense water activities.

Pro-Tip: Before starting an intense activity, such as jet skiing or surfing, slide the Quiksilver adjustment mechanism so that the cord fits tightly at the back of your head. This will create an absolute "lock" on your face. Conversely, when relaxing on the boat deck, leave the cord completely loose so the glasses hang comfortably around your neck. After each outing, don't forget to rinse it with fresh water to maintain the elasticity and softness of the fibers!
