I've been rocking this goggle for 2 seasons now and it's been awesome!
Initially, the goggle held up extremely well in storms, rain, and sunny weather. However, I decided to scrape the interior anti-fog coating off one powder day. So now I've had some issues with fogging when the vents are closed, but other than that the performance is top notch.
I've never had any problems with clarity or anything like that, and the lenses have held up extremely well scratch-wise.
Personally, I'm a big fan of the design just because it's so simple and clean.
The main reason I love these goggles is because they fit my face so well. I have a long-ish thin head shape, and the goggles fit perfectly with my Maze helmet, whether it be outside or inside the helmet.
Overall the Phenom is a fantastic goggle. It takes all the elemts that I like about the fuse and the prodigy and melds them into one goggle. It has its own identity in terms of styling, and doesn't attempt to look too fancy. Overall a dynamite goggle and I highly recommend it!
As with all other Smith products, the quality is top notch. With a variety of lenses, you're good to go in all light conditions. I have had very little fogging difficulties with this goggle thus far.
I very much like the styling of the Phenom. I like how it is a good mixture between square and rounded design. Once again, its a perfect marriage of the style of the Fuse and Prodigy. This particluar model has swarovski crystals on the strap (which my girlfriends mom goes crazy over) so it adds a little bit of zing. The colour choices of the phenom are great, and it will look good with most of your outfits.
The Phenom exists somewhere between the Prodigy and the Fuse. The fit I find reflects that idea almost exactly. It creates a tighter seal than the fuse does around the face, but is not nearly as bulky as the Prodigy.
I've been rocking them since the beginning of the season and I haven't had any problems. I would imagine that they'll be like all other Smith products, and be durable as all hell. Just make sure to treat your lenses well! Don't wipe them with anything but the bag, and I highly recommend getting one of Smith's hardcases for your goggles. By far the best way to travel!
