with Numa’s Durable X-Frame Optics (continued)
we were done torturing the frame in the lab it was time to see just how well
these optics would really perform in the field. I wore them for a few months
fishing for everything from largemouth bass at local Northern California lakes
to trout in Nevada. Because the X-Frame is designed for tactical applications I
also decided to expand my normal test metrics and utilize them in the snow for
I’ve bought many pairs of interchangeable sunglasses over the years but I find
that I typically use just one lens 90% of the time. This is not always because
that one set of lens tint is what I actually prefer but because it is just so
aggravating to wiggle and snap lenses in and out of frames that are hard to deal
with. This is simply not the case with the X-Frame which has a very easy to
manage Pivot-n-Slide™ system.

the polarized smoke lenses (right) improves depth and contrast
holds the lenses in place in the nose section while the outside edges rest
freely against the frame. This allows lenses to be locked into place quickly,
and to remove them anglers need only press and pivot their finger on the surface
of the lens and it snaps right out.

In terms of fit I found
the X-Frame to be a little tight, putting pressure on my temples on both sides.
I can’t really fault the X-Frame for my enormous head though, and other editors
that tried the sunglasses found them very comfortable. As with all sunglasses
fit will vary for each and every person and I feel the X-Frame is best for those
that prefer medium sized frames. Part of what makes the X-Frame so good for
extreme activities as well as fishing with all day long is that they feel

the X-frame is among the lightest pair of sunglasses we have tested to date. If
not for the tight fit on me personally I would have hardly even felt like I was
wearing sunglasses at all.
replacing lenses is quick and easy on the X-Frame
That tight fit did make it
very easy to keep them on however, and during snowmobiling when things really
got bumpy other sunglasses would creep downwards while the X-frame stayed firmly
in place both due to the face hugging fit and non slip rubber nose pads. The
lenses on the X-Frame provided excellent coverage from wind when
on the water or the snow.
with the Numa X-Frame
In terms of
optical clarity I found the polycarbonate lenses to be good, but not as crystal
clear as some glass lenses that we have tested, on the plus side the
polycarbonate is much lighter. All Numa lenses provide 100% protection from
harmful UVA, UVB and UVC rays.
The snow was
much brighter than the surface of the lake and the X-Frame not only improved
visibility but shielded my eyes from the wind at high speed
