How to Put Chums on Sunglasses?

If your sunglasses keep slipping off during hikes, boat rides, or workouts, chums are the simplest fix. These adjustable straps loop onto the arms of your frames and take about a minute to attach — and they can save a pricey pair from ending up at the bottom of a lake.

Here is exactly how to put chums on sunglasses: slide each arm through the loop at the end of a strap, pull the loop snug near the tip of the arm, then set the length with the sliding bead so the shades sit comfortably whether they are on your face or hanging around your neck.

Understanding Chums

Before we delve into the process, let’s familiarize ourselves with chums. Chums are typically made of durable materials like nylon or neoprene and come in various colors and designs. They consist of two separate pieces, each with a loop at one end and an adjustable sliding bead or cinch at the other. The loops are designed to be attached to the arms of your sunglasses, while the adjustable bead allows you to customize the fit.

Choosing the Right Chums

When selecting chums for your sunglasses, consider both style and functionality. Opt for chums that complement your sunglasses‘ design and color. Additionally, ensure that the chums are made from quality materials that can withstand daily use and provide a secure grip on the sunglasses.

Attaching Chums to Sunglasses

Follow these step-by-step instructions to attach chums to your sunglasses:

1. Start by laying out your sunglasses and the chums on a clean, flat surface.
2. Identify the arm of your sunglasses where you want to attach the chums.
3. Take one chum strap and locate the loop at one end. Hold the loop with one hand and the arm of the sunglasses with the other.
4. Insert the arm of the sunglasses through the loop of the chums, ensuring that the loop is centered and aligned with the end of the arm.
5. Pull the loop tightly around the arm, making sure it is snug but not too tight to restrict movement.
6. Once the loop is securely around the arm, take the loose end of the chums with the adjustable bead or cinch.
7. Slide the bead or cinch towards the loop, tightening the chums around the arm.
8. Adjust the length of the chums by sliding the bead or cinch up or down. This allows you to customize the fit according to your preference.
9. Repeat the same process for the other arm of the sunglasses, ensuring that both chums are attached symmetrically.

Testing the Fit

After attaching the chums, it is essential to check the fit and comfort. Put on the sunglasses and assess if they feel secure and snug on your head. Move your head around and see if the chums hold the sunglasses in place. If the fit feels too loose or too tight, adjust the bead or cinch accordingly until you achieve the desired fit.

Maintenance and Care

To prolong the lifespan of your chums and sunglasses, it is important to take proper care of them. Here are a few maintenance tips:

1. Clean your chums regularly with mild soap and water to remove any dirt or sweat.
2. Avoid exposing your chums to excessive heat or direct sunlight for prolonged periods, as this can degrade the materials.
3. Store your sunglasses and chums in a protective case when not in use to prevent damage or loss.
4. Inspect the chums periodically for any signs of wear or damage. If you notice any fraying, stretching, or weakened areas, consider replacing them to maintain optimal security.

Once the chums are looped on and the bead is set, your sunglasses are ready for kayaking, running, or yard work — give your head a good shake to confirm they stay put. One tip that saves frames: re-check the loop tension every few months, since nylon and neoprene straps stretch slightly with daily use and a quick re-tighten keeps the fit secure.
