Optics Review

Going Tactical with Numa’s Durable X-Frame Optics (continued)


The polarized smoke lens is the one that anglers will use most of the time and was good for all but very low light conditions in which a lighter brown lens is actually preferable. While the interchangeable brown lens provided in the kit is a good shield from the sun because they are not polarized they are not as good for bright days on the water where eliminating the “mirror effect” is a primary factor. In the snow the dark smoke lenses also proved to be excellent and did a very good job shielding my eyes from harsh reflected light.


The small gap in the center of the lens helps improve airflow and reduces fogging


The anti-fog venting provisions on the X-Frame also worked well and I found these sunglasses simply did not fog nearly as much as other sunglasses, it certainly helps that the lenses themselves are finished with an anti-fog coating. Once in a while when the lenses got splashed with boat spray it was necessary to wipe them, and because Numa bundles the X-Frame with a cleaning cloth I didn’t have to resort to wiping them with the bottom of my shirt.


The reinforced hinges can hold up to a lot of torque


Durability: The X-Frame did extremely well in our durability tests, we sat on the sunglasses, threw them into our bags, even stepped on them, and through it all the frames always returned to the right shape and even resisted scratches amazingly well. The anti-scratch coating on the lenses helped guard against grazes and impacts and in real world applications the lenses will hold up very well.


The brown lenses are good for lower light conditions


The one area I was originally concerned about was the hinges which looked like they could snap apart if there was enough torque pressure applied to the frame, but after a series of twists and pulls I was satisfied that the hinges were reinforced sufficiently to the point where they could hold up to some serious abuse. In the center of the X-Frame extra MemFibr™ is used to provide more strength over the nose-bridge. Overall the X-Frame scores very well in the durability category and can handle everything from a day on the lake to extreme sports with ease.


The brown lenses locked and loaded


Price & Applications: The X-Frame retails for $119 dollars which is a very reasonable price for these sunglasses. In the optics category brand name plays into the overall cost of the glasses, probably ore than most types of tackle, and while Numa may not yet be as well known to anglers as Costa or WileyX they are committed to this market. Hopefully more fishing retailers and e-tailers will carry the brand, but for now anglers can buy the sunglasses direct from Numa or Extreme Outfitters.


A look through the brown lenses (right), even in bright sun they also improve contrast


Numa provides a Lifetime Warranty on their optics and this warranty not only covers the frames but the lenses for normal wear and tear. So what does Numa consider “normal wear and tear?” For Numa their unique definition of "Normal wear and tear" includes but is not limited to: scaling a cliff face, downhill mountain biking or skiing, parachuting, hiking rugged terrain, dropping your Numas on a hard surface, accidentally stepping or sitting on them, and even letting your toddler play with them. Now that is impressive coverage!


The Numa X-Frame is good for a wide range of outdoor activities beyond fishing


Ratings: (We've re-calibrated our ratings standard for 2008 and have included a key at the bottom of the following matrix as a guide):

Numa X-Frame Sunglass Ratings (?/10)

Construction/Quality A seemingly simple construction that delivers when it comes to durability thanks to use of a special Swiss made material that is both lightweight and resilient 8.5
Performance The X-Frame performed well in all categories, and while the optical clarity was good we found some glass optics clearer, but much heavier. The X-Frame delivers a great overall balance of performance metrics 8
Price Great price for a interchangeable pair of optics 8.5
Features Plenty of features here including the frame material itself, an interchangeable lens system, and excellent frame and lens durability. The bundled floating case is a very nice touch 9
Design (Ergonomics) This frame is best for anglers that like mid sized sunglasses, it was a tight fit for me but stayed on well. I did appreciate how lightweight the X-Frame was 8.5
Application Great for anglers but can be used for many other applications because the frames are so lightweight and durable. It is no surprise that the X-Frame is popular among extreme sports enthusiasts 9

Total Score

Ratings Key: 1 = terrible : 2 = poor : 3 = lacking : 4 = sub par : 5 = mediocre : 6 = fair : 7 = good : 8 = great : 9 = excellent : 10 = unbelievable!

Pluses and Minuses:

                 Plus                                    Minus

+ Extremely durable frames - Not as crystal clear as some glass optics
+ Very lightweight  
+ Finally a sunglass with a easy to operate interchangeable lens design  
+ Reasonable price  
+ Lifetime Warranty with excellent coverage  


Conclusion: It is no surprise that the X-Frame has become popular among extreme sports enthusiasts and military personnel, this robust pair of sunglasses can take a lot of punishment. While other sunglasses boast durable frames Numa delivers on all fronts, the frame material can be bent in different directions and will not break or become misshaped, the lenses hold up well to abrasion, and the hinges and nose section are all reinforced, and to top it all off the company backs the sunglasses up with a warranty that covers just about everything other makers would puke on.


Anglers will appreciate the Numa X-Frame's quality polarized performance on the water, light overall weight, and excellent durability


Angler’s will like the way the X-Frame stays firmly on and blocks wind at high speed, and while optical clarity doesn’t match some glass lenses, the overall performance of the X-Frame is very balanced, especially when you factor in the very reasonable price point. The Numa X-Frame successfully delivers tactical performance for everyday anglers and when it comes to holding up to the rigors of tournament fishing this pair of sunglasses absolutely completes the mission.
