Backpacking
Background:
For the last 15 years, backpacking has become
a passion. I am a four season backpacker and an off-trail navigator.
Although I do take yearly trips to the American West or Southwest, the
majority of my trips are in Michigan and Canada. My pack weight varies
considerably, but my base weight is under 20 lbs (9.1 kg). I am primarily a
tarp camper, that averages over 50 nights a year backpacking in a huge
variety of weather conditions, including relentless rain, wet snow and sub
zero temps.

I received more than the standard package of three lenses. Three additional
lenses were included for different conditions. The lenses I received and
tested are:

lens tint with silver mirror, it cuts light and glare by reflecting it away
from the eye

lens providing the best vision for the widest variety of light
conditions
Yellow (and Yellow Max): for low
light and flat conditions

reduces 99% of reflected glare from water, sand and pavement
Sienna (and Sienna Max): for sunny or
slightly overcast days
Long Term Testing
Data
Field
Location/Conditions:
During the long term testing period of four
months, I have backpacked a total of twenty-three nights ( five
trips). Most of the trips were in the two to five day category
with the longest trip being eleven days. My first two back
country trips during this period were taken in the Lower Peninsula
of Michigan. Conditions consisted of highly deciduous forest with some open
pine forest and river walking. Late spring to summer-like weather varied from
semi-cloudy to sunny with temperatures from 40F (4C) to 85F
(29C).
Two of the trips were located in the Upper
Peninsula of Michigan - again mostly deciduous forest, river canyons,
open shoreline, and lots of bushwhacking through dense cover. It's been an
unusually hot summer in this part of Michigan with the temperatures ranging
from lows of 40F (4C) to highs of over 90F (32C). Semi-humid conditions
have prevailed with less humid evenings.
My longest trip was taken to the north shore of
Lake Superior in Ontario, Canada. Conditions consisted of dense boreal forest,
open rock outcroppings, river canyons, and open sandy beaches.
Temperatures during this eleven day trip were moderate. The highs
were from 80F (27C) to lows of 50F (10C). There were only
small intervals of rain, with sunny partly cloudy skies
prevailing.
Although all of these trips were at low
altitude ranging from 600 ft (183m) to 2000 ft (610m), there was
significant elevation changes - lots of climbing and descending. The
Smith Theory lenses have not only been my constant companion on these back
country trips, but they have also been worn on an almost daily basis for
other activities. These activities include road and trail running, bicycling,
day hiking and driving.
Summary
Testing
Thoughts:
Through the process of extensive testing of the Smith Theory lenses, I have
come to the conclusion that they are an outstanding product.
I have addressed every initial concern that might occur with these glasses
and I have found none to be significant (see cons below). They are highly
comfortable. The lenses have been easy to change once I figured out how to do
it efficiently and they have been highly indestructible even when stored in
the soft-shell case that was provided. I have put them through the constant
grind of bushwhacking and they are still scratch-less and stay put through the
extent of my activities.
After utilizing all of the lenses, I have developed my preferences
for favorites. Overall, the Platinum Mirror lens has been at the top of my
list. It is the most versatile to me for a variety of activities including
driving. The silver mirror finish reflects glare away from the eye especially
important in long distance vision.
I also love the RC36 lens when I am traveling deep in the forest. It makes
everything doable. I can readily see all the rocks and brush that I might
clumsily miss with darker lenses on my face. The depth perception experienced
was especially keen when the light faded in the evening.
I thought I would be more enamored with the Polarized lenses while walking
along or canyoneering in the water, but it may be due to the fact that most of
my back country days were spent in semi-cloudy conditions and not in full sun.
Two of the lenses that I tested were the Max version--that is, they had
longer lenses for more eye protection. One of those options was in the Yellow
Max version and the other was in the Sienna Brown Max version. I found the
later to be useful, but the former to have little use for me. It had to be
raining with dark gray skies for me to use the Yellow version, as soon as the
sky lightened up even a shade over dark gray, they were too bright for my
sensitive light blue eyes. Ideally I like the concept of the longer lenses, as
I do a lot of extreme bushwhacking so my "perfect" lens would have been a RC36
Max lens for this purpose. I checked the Smith Optics website and found that
the Max lenses could be ordered in 16 different versions including the RC36
Max.
I will continue to use all of these lenses over the long haul. It will be
interesting to see if these lenses perform equally as well in the deep cold of
winter. As indicated in my field report for this
product, I was able to utilize them for late winter snow activities but most
of the overall testing in the last six months was done at above freezing
temperatures.
Pros:
- Highly indestructible
- Versatile
- Curb appeal
- Great fit for a small face
- Comfortable nose and ear pieces
- Complete eye coverage
- No slippage when sweaty
- Easy to clean
- Changeable lenses stayed in place during
exertion
- Impact resistant
- No signs of wear after extended use
- Complete glare coverage around eye
area
Cons:

Remarks
This is my first pair
of Smith Optics glasses and it won't be the last. I look forward to
investigating other options that they market. I am highly pleased with
their outstanding function and performance capabilities.
Thanks to Smith Optics and
BGT for this great opportunity to test such an outstanding
product.
