The test product is a pair of lightweight frameless (the frames
don't wrap around the lenses) sunglasses with rubberized non-slip
nosepad and interchangeable polycarbonate lenses. It comes
with three colors of interchangeable lenses and is available in
five frame colors, each with a different primary lens color.
To be more precise, all five frame colors come with one lens
intended to be used in most situations. Three of the five
come with two additional lenses: AC Red, and Clear.
The frames and lenses have a wrap-around shape, as if they were
designed to keep wind out of the wearers eyes.

I put them on and walked outside on a sunny day. They are
quite comfortable with no undue pressure on my temples. The
frames are quite straight and do not curve down behind my ears, so
they may be susceptible to falling off when I lean forward.
I am looking forward to getting these sunglasses out hiking in
the Arizona sunshine and seeing (literally) how they do!

My wife and I do local day hikes several times per week in one of the mountain ranges surrounding Tucson. The image in the above collage at lower left is from a hike in Catalina State Park in Oro Valley, Arizona.
Hiking in the early morning means the sun is at a low angle, so even my wide-brimmed hat does not keep the sun out of my eyes. The Tifosi Slice sunglasses had plenty of protection to prevent eye strain and keep my cataracts from getting worse!
The Tifosi Slice sunglasses are ideal for cycling: their
wrap-around frameless design keeps the sun and wind out of my
eyeballs. I did several morning cycling jaunts each a couple
of hours long with the glasses (see above photo collage at lower
right). I like the way they stay on my face, no slippage
down my nose. I tend to look off-axis a fair amount when I
am cycling: up to see where I am going, and off to the left to
check for traffic. Off-axis viewing would be likely to
expose optical flaws in the lenses, but I didn't pick up on
Same trail as my prior outing, just a lot shorter. My prior trip was a scouting mission for a trip I planned to lead with the Tucson Backpacking Meetup group, and this trip was that Meetup organized hike. I billed it as "beginner-friendly", which indeed it was: short hike with gradual elevation change and a scenic campsite with water and fire ring.
We had brilliant sunshine on day 1, and we had the sun at our
backs. Day 2 had high clouds, but we were hiking into the
sun. The sunglasses performed well in both situations with
no issues. We weren't hiking long enough for any comfort
issues to pop up, but I will say that they felt good enough that I
generally forgot I had them on.
So far I have not used the alternate lenses. On backpacking
trips, I generally don't bring the lens storage case where the
lenses are stored, so I would have to decide which ones to use
before the trip. Overall, I have been quite pleased
with the Tifosi Slice sunglasses, having experienced no major
These are not normal times. The bad news is I didn't get in any overnight backpacking trips during this period. The good news is I got in a day hike almost every other day, along with frequent bike rides, during all of which I was able to use the Tifosi Slice sunglasses. I didn't keep records of my day hikes, but I'd estimate I got in roughly 50 hours of use:
