Frame Adjustment

Temple Adjustment


Frame Adjustment

Tighten the Fit
If your frame feels too wide, begin to bend the frame in small increments. Face the lens towards your chest, and place your thumbs on the edge of where the lens meets the bend in the frame. Firmly but gently, make small pulses to adjust the frame inward. Try them on, and continue to adjust as needed.

Loosen the Fit
If the frame feels too tight, again face the lens towards your chest, with your thumbs at the edge of the lens, and pull gently outward in small movements.

Temple Adjustment

Loosen the Fit
After wearing your Gatorz for a few hours, you will notice if the temples are providing a comfortable fit. If they are placing pressure on your head, hold firmly at the base of the temple and pull the end outwards with repetitive pulses. After adjusting both sides, try them on and determine if you need to make any more adjustments. You may need to wear them for several hours to determine if you’ve found the right fit.

Tighten the Fit
If the template feel too loose, place your hands as you would for a temple adjustment and pulse the end inwards until you feel you’ve reached the right placement. Try them on and wear them to determine if any further adjustments are needed.


Raise Glasses Closer to your Face
If you feel like they’re sliding down too easily, pinch the nosepiece closer together. When making any adjustments to the glasses, we recommend making small changes, rather than big adjustments. This will help you move easily into the right fit without overdoing it.

Separate Glasses from your Face
Start by placing the glasses on your face. If they’re sitting too close to your eyes, pull the nosepiece away from the frame. Keep in mind, most Gatorz offer a wrap style fit, so they may take a little getting used to.

I love it

Fits great. Unlike other glasses this does not require me to get a special asian fit for it. Great look and easy to run in.

Every pair is awesome

I have literally no complaints with gatorz. Every pair has fit perfectly, they are rugged without the weight. Clear and stylish. I used to sweat by oakleys until I got these and I'm hooked!

Delta M4

Better than expected. I thought the blue lens was not going to be dark but after putting them on it was dark lens like any other Gatorz sunglasses.

Best sunglasses I have had in a long time! All day comfort, built like a tank, quality work and materials, and made here in America. I also like the fact that some of the profits from the purchases go to support our military ( after all they did write a blank check for our freedom) and law enforcement (people who have to do things that most wouldn’t do) members . Support those who support you. Thank you Gatorz!

M4 Delta Gunmetal w/Blue Mirror Lens

These are great looking and fitting glasses! I’m very pleased with them! The fact they are American made is extremely important to me! The metal frames stay cool even in the heat of summer. I highly recommend Gatorz products!

Cool shades

Bought these because made in USA and gold lenses look super sick. Product is high quality. Frames are light, but not the cheapo light - the aluminum feels very sturdy. I like the double hinges at the temples. I also like that the lenses are not recessed like most glasses with a lip that catches all kinds of dirt and junk. Very pleased with my purchase

The best sunglasses

Look no further for USA made Sunglasses. I love these glasses. They are very light and the lenses are the perfect shade of dark. The build quality is perfect; I’ve only had for a couple of weeks but they seem very durable. I will be buying another pair.

My Favorite Glasses (of many)

I've been wearing Gatorz for years and had them all over the world. They hold up great. The Deltas are fantastic and fit well with the same durability of my old Magnums. I now have three pairs of Gatorz. I'll continue to wear them for years to come.

Best shades I’ve ever owned.

I’m normally a Wraptors guy, but these M4s are awesome. I use them for skydiving and shooting. Absolutely love them.

The best in Eyewear is here

First off, I have had many pair of Gatorz for years, this is one of my favorite pair owned. My only regret is not getting the pair that I did. I have the orange lenses in my other styles and would like them in this… either way, I had a pair of Gatorz on when I when down on a motorcycle. The aircraft aluminum and lenses took the brunt of the asphalt grind on my orbital and I did not lose my eye, but ended up with my broken orbital and road rash. I love Gatorz!!! No better eyewear on the market!
