Shades that are as hardcore as you.

Ever gotten a bug in your eye when you're descending at 50mph? Kind of a bummer, but with Smith's Pivlock Arena Sunglasses, you'll never have to worry about it again. The Pivlock offers an enormous and uninterrupted field of view thanks to its bridgeless wraparound design, along with the crystal clarity of water-, oil-, and dirt-resistant Carbonic TLT lenses. It's designed to fit every face comfortably, too, with two-position adjustable nose pads and slide-on temple tips, both made of a hydrophilic material that actually becomes sticker as it gets wet, so sweat won't be a problem. Best of all, the superlight TR-90 frames feature Smith's innovative Pivlock lens-interchange system, which lets you swap out your lenses in a hurry so you can always have the perfect shades whether you're running or cycling.

Great visibility, Easy to change lenses

  • Familiarity: I've used it several times
  • Fit: True to size

Bought these for 3 reasons:
1. No frame to obstruct my vision
2. Fit on top of my Overtake helmet
3. Price (on sale)
I'm very happy on all 3 counts. Changing the lenses is easier than other glasses I've owned. Comes with a nice case to hold the glasses and spare lenses. My only knock is I noticed a small scratch already, and I'm pretty careful with them. I recommend them.

Gret Visibility

  • Familiarity: I've used it several times
  • Fit: True to size

I love my Pivlock Arenas. I snagged a pair of Asanas first, but found them to be too small in the lens, but these fit perfectly. The clarity is awesome, and the fact that the frame doesn't surround the lens makes your field of vision huge, and keeps it unobstructed. The fit is comfortable and I don't even notice they are on my face while riding, which is a good thing in my book.

versatile product, great performer

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Being my first glasses with interchangeable lenses, I was nervous that with my relatively poor fine motor skills they'd be hard to change. Not the case at all.

Last year, I did snap one of the tabs on arm, which was totally my fault. I was rushing to swap out the lenses at a red light on my way to a ride I was late to (tisk tisk), and turned the arm the wrong way with a lot of force. I contacted Smith directly, very honestly told them what happened, and they sent out a replacement arm no questions asked. Great consumer support.

Additionally, the optical clarity of these glasse are great. The amber lens makes greens really pop, which made them an easy choice for a week-long backpacking trip I did last fall.

High-speed descending is great in these. The lens does a great job of shielding the wind, and the absence of a frame lends itself to an excellent field of vision.

I've had my Pivlocks for three or four years now, and I love them today just as much as I did when I first got them. Would recommend them to anyone looking for a versatile pair of cycling glasses.

Arm snapped 3rd time I wore them

  • Familiarity: I've used it several times

I liked these until they broke the 3rd time I wore them. I had them on the neck of my t-shirt, and when I pulled my pack off, one of the arms broke where it attaches to the frame. A girl I was with said the same thing happened to hers. I contacted Smith and they would not cover it under warranty, saying it's not a manufacturer defect. I'm now looking elsewhere for a more sturdy pair and/or a pair from a company that better stands behind its products.

Perfect Fit, Clear Lens.

Not only do these fit perfectly on the Smith Overtake helmet when I'm not wearing them, but they're a perfect fit on my face with a crystal clear lens. Plus, they just look really good too..

These are great

  • Familiarity: I've put it through the wringer

These Smith glasses are great! I've used them extensively for mountain biking, trail running, and skiing. They have a great field of vision, vent well, and feel solid in the hand. They also make you look so fast!

From Tree to Trail

  • Familiarity: I've used it several times
  • Fit: True to size

I'm an arborist and I actually bought these for climbing work. As my current shades/safety glasses (sun clouds) would slide down the narrow bridge of my nose when I would get sweaty. Not in these bad boys. Wore them a couple days already and the glasses don't move at all. They did scratch pretty easy however. But then again they're designed for mountain biking not dodging limbs 65ft up a Douglas Fir. Overall very nice and affordable.

Everything you're looking for

  • Familiarity: I've put it through the wringer
  • Fit: True to size

These glasses are perfect for the job. They're stylish and offer the perfect amount of protection. The lenses are great and are easy to change. It comes with two lenses and an awesome case to store them in and keep everything protected while traveling.

Great glasses, just weren't for me

  • Familiarity: I returned this product before using it
  • Fit: True to size

Really wanted these glasses to work out, but the bridge of my nose just didn't agree with the adjustable nose pads. I'd say I have a medium to small sized face, and coverage of the lens was good, didn't look too big on my face, and didn't have a large gap between my temple and the frame.

Love em

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Everything you'd need in a pair of bike shades. They are light, have an adjustable nose piece, are easy to clean, easy to swap, and come with 3 lenses for all conditions. That and they look great.

Great glasses!

I bought these glasses after my last crash broke my helmet in 4 places (Yes, I'm finally ok after months!) So I purchased a Smith helmet and saw that these fit into the helmet upside down, pretty cool option so I bought them...

I'll have to give the glasses a 10/10. Mine came with 3 lenses, clear, medium gray and the Ignitor (? I think, red lens) darker lens. I've got a massive head and they fit me well ,no movement while riding and I've probably got 3,000 miles with these glasses so far. You forget they are on your head. Lightweight. The only time that I've had them fog up was at a traffic light or something when I stopped moving but quickly cleared up at the least bit of breeze when you start moving again.

If I had a complaint, it would be that they don't really stay on the helmet very well. I've put them up there and as long as you are only walking around it's fine, but they will fall off on bumps while riding. I rarely leave them up there while riding so it's not really an issue but thought it might help you make a decision. I'd buy them again in a second because on the ride, they are great. Nice case too, which holds all three lenses and the soft cleaning cloth and that fits nicely in my upside down helmet in my cycling bag...

I had my last pair of riding sunglasses for about 10 years and loved them, so they were a majorly tough act to follow. But I am pretty so stoked to have found the Arena's, so far they are pretty rad.

I have a medium sized women's face shape and wear a medium helmet and these seem to fit pretty perfectly. No foggy on hot sweaty climbs, and they keep the dust out on a filthy MTB descent.

I haven't had a chance to try out the different lens' but -- it's nice to have the options!

Ok maybe not scientifically proven, but I've used them and I totally dig them. I have a medium sized face and they fit pretty well. I mostly wear them mountain biking with a Smith Forefront helmet, though like Jennifer Newman commented, they do work well for running. Photo is of me sloggin' my way up Mount Baldy mid Discrete Peak Series Snowbird race.

-First off, they flip and clip onto a Smith Forefront helmet and it is awesome. Its relatively secure - I'll throw em on the helmet for a lot of the climbs.
-Next awesome bit is that they have three lenses that come with it - I bought the Green Sol X and it came with a mirrored gray lens and clear in addition.
-Swapping lenses out is actually a cinch. Some frameless goggles and sunglasses actually are more of a hassle to swap, these take 15 seconds to do.
-Pretty big lens, making it a good dust shield and keeping the sun out of the eyes!
-These make you go faster. Cause they look fast and you know, science and stuff.

-Green mirror has scratched a bit, not sure if its just carelessness or if it was just easy to scratch. Something to note regardless.
-Wish the arms could be bent slightly, but they still stay on face relatively well anyway.

Needing an athletic pair of shades? Happen to already have a Smith helmet? Want to look fast & go fast? These shades are for you!

These are a great activity focused sunglass. They come with 3 lenses that are easy to swap out, and fit great under a bike helmet. They stay on your face and don't slip.

Cool for Chicks too!

Love these. Great value with the 3 lenses. Easy to change lenses out. Work as good running glasses too. I have a small face and they still fit and look good on me. Would definitely buy again. Never fog up and when sweat does drip down it wicks away with no staining. Super pleased!

I've read in these reviews (and others) that this pair tends to fog up (... but still receives pretty good reviews). Is there any spray or product I can use in the event this is really the case?

Dawn dish soap: put a coating on both sides of the lens, let it dry, then buff it clear....


  • Familiarity: I've put it through the wringer

When people see someone wearing these shades they always seem to say "Woah. They must be fast." And I'm pretty sure that these shades do make you at least 30% faster. But don't quote me on that. You can even change the lens super fast. Some might say "But don't the 100% speedcrafts ( make you 100% faster?" To that I would say "I don't know. Maybe? Sounds legit though."


Great shades

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I've had these since they first came out and they have always done a great job at protecting my eyes. Not only from the light, but from objects as well. It would be nice if they had RX available, but due to the lens curve, they just aren't able to without the adapter that they have. Either way, these are still great. The lens interchangeability is super fast so you can be dialed for what ever conditions are put in front of you. Smith has a huge range of lenses for any light condition so you can always be set. They fit well on the face and the rim less design helps keep sweat from building up on the inside frame and lens like it has a tendency to do. The compatibility with the Smith Forefront helmet is pretty spot on too, as they fit perfectly. They also sit in the front or rear docking design of the helmet fairly securely as well, though one could still have the possibility of them falling off the helmet depending on what they are doing. I use these for just about all my outdoor activities. backcountry touring, hiking, cycling, or even as safety glasses with clear lenses in them. Definitely versatile

Great shades

Nice Shades

Use these on all of my Mt. BIke rides. Having the ability to switch between 3 different lenses is great. I wouldn't wear these around town, but still like the look. Anything i buy for my bike is all related to performance and these fit the bill.

As always great service from, makes it easy to spend money and be confident with all of your purchases.

gotta embrace 'em!

My tipping point for deciding to invest in a pair of "sport" glasses was when I crashed my mountain bike, landed on the side of my face, and had my old pair of sunglasses (a casual pair of Zeals) slam so hard into the side of my nose that it was dented briefly and I was left with a puffy/black eye for about a week. The other scary aspect of wearing those in a crash was that they could have just as easily broken, and I could've been left with plastic shards in and around my eye.. good times!

The Pivlock Arena contours pretty closely to your face, so if you do manage to have your head meet the ground (or any other solid object), the risk of being "punched" in the nose by them is pretty mitigated. The nose pads, made of 'hydrophilic Megol,' are very grippy (the hydrophilic part means the gripping power increases when introduced to moisture, according to Smith) and they're soft enough to be forgiving if you do have a head-on impact.

Apart from their face-saving qualities, what I've really been enjoying about these is the extra lenses they come with! Swapping the lenses out is pretty easy, and I've ended up swapping to the clear lens a lot more than anticipated during rides, especially now that it's getting dark earlier.

Only downsides so far are that they do fog up on me on most rides, and that replacement lenses aren't available here on Backcountry (but you can find them on Smith's site.)
