Review

As a triathlete living in Colorado, I’m rarely without sunglasses.  I’m a woman, who needs a smaller (ish) frame and I love sunglasses that I can take from the trail to coffee.

Also: I love purple. And sunglasses that are frameless on the bottom of the lenses, which is something that I prefer when I run.  I helps to avoid a sense of tunnel vision and helps to keep my vertigo in check.

The Tifosi Optics Sanctum SL Sunglasses just look cool.  They have a moto/aviator-esque vibe that somehow also looks a bit futuristic. Basically – they’re fun.

But better than just appearing fun, the Tifosi Optics Sanctum SL Sunglasses deliver performance at a very affordable price ($40).

I’ve been wearing the Tifosi Optics Sanctum SL Sunglasses on several runs, many of which were very warm and sweaty.  The glasses offered great ventilation and coverage.  I didn’t have any issues with too much ventilation (which makes my eyes water).

The mirror coating (Purple Mirror AR, in my case) on the Tifosi Optics Sanctum SL Sunglasses is medium opaque.  People can still see your eyes at certain angles, but for the most part, the lens mirror tint projects it’s color and opacity well.

I personally love how light the Tifosi Optics Sanctum SL Sunglasses feel. The combination of the polycarbonate lenses and Thrive plant based frames make the sunglasses feel like they’re barely there.  There’s no weight on the bridge of your nose or on your ears from the glasses.

I did find that the Tifosi Optics Sanctum SL Sunglasses do migrate down the bridge of my nose a small amount.  I have a pretty small face and these frames are considered “medium-large”, so this isn’t a huge surprise or a deal-breaker.  The glasses do manage to find a spot on my nose and eventually settle into place, staying put over the course of an interval run. The frames also work well with a variety of brimmed hats, ranging from trucker style to running caps.

The Tifosi Optics website doesn’t have a VLT (variable light transmission) rating, but I would classify the smoke lens tint as medium for light blocking: not so dark that you can’t see in the shadows, but I am a bit squinty in bright light.  I do prefer wearing these when combined with a running hat (with a brim) to offer a littler more sun protection.

Compared to other sunglasses at this price-point, I think the Tifosi Optics Sanctum SL Sunglasses are on the better range.  I’ve dropped these sunglasses a few times (it happens!) and the lenses are indeed scratch resistant.  I also appreciate how light they feel and how clear the lenses look.

Closing Thoughts

The Tifosi Optics Sanctum SL Sunglasses are a fun and stylish option for outdoor pursuits at a very reasonable price.  These are considered “lifestyle performance eyewear”, meaning that they’re made to go from the courts or trails and into everyday activities.

The Tifosi Optics Sanctum SL Sunglasses are available in 8 different frame and lens options.

She placed 9th in her age group and was the 1st American woman in her age group.
Somewhere along her triathlon journey, she picked up deep love of cycling. Cycling encouraged her to see landscapes in a new way, learn new skills and to develop self reliance; now she often goes and does Type 2 rides just to see if she can do it.  She’s got all the bikes: gravel, mountain, fat bike, time trial and road.
She is even known to combine her love of camping and cycling and go off on solo 24 hour overnight bikepacking trips in the mountains of Colorado. In addition to bikes, she teaches yoga, lifts weights, skis, SUPs and has recently purchased a campervan.

Erin is a former Montana park ranger with a degree in environmental engineering.  She loves getting into technical details while putting her gear (and herself) through the paces. She shares her home in Colorado with her husband, Will, and her 3 cats (Zipper, Brewtus, and Simcoe).
Fall and winter 2025 will bring Erin to the “Adventure Side”, with many camping, vanlife, bikepacking, and mountain bike rides. Once the snow flies, she can be find resort skiing, fat biking, and triathlon training (inside and outside).
In 2026 Erin took the National Championship in her Age Group for the USA Triathlon Cross Tri. She’s also racing the a National Championship Road Sprint and Olympic Distance race in Milwaukee and a few other off road triathlons and bike races.  In 2027, she will represent Team USA at the World Championship Cross Triathlon in Edmonton, Canada. She’ll also save lots of room for adventure time with her friends and husband.
When not adventuring, she can be found on a sunny patio somewhere, drinking beers with her husband.
