Thought I'd do a follow up post on my mask experience. I was able to get my hands on both the Atomic Frameless 2 (msrp $199) and the DGX Ultra View Frameless ($25). I spent an hour in the pool with them this evening swimming laps with mask/fins/snorkel, then about another hour diving, equalizing, clearing, removing and putting back on, etc.
Similarities:
Both have nice soft seals and a lot of glass to look through.
Both fold up pretty small to fit in your pocket for a spare.
Peripheral and vertical views were very nice on both masks.
I couldn't tell any difference in the expensive glass of the Atomic and DGX in the evening shaded pool. YMMV in less clear water.
Both sealed exceptionally well for me.
Differences:
I saw a little more of the black nose pocket with the DGX than I did with the Frameless 2, but not enough to annoy the hell out of me and darn near make me cross-eyed like the Atomic Venom I tried the other day.
When I tried the DGX on, it felt like it might leak at my temples, but when I got in the water, the pod bay doors slammed shut and kept the water out.
The DGX felt a little wider than the Frameless 2 (regular size), but both still sealed very well.
The Atomic came in a small hard case. I had to fiddle with the mask to get it stuffed in and snapped shut.
DGX came in a double mesh bag. Inside is fine mesh, outside is course mesh, closes with a drawstring.
There is no branding on the DGX. It's probably sold as other brands, but DGX seems to be a great place.
The DGX only cost $25.
Negatives:
I had only two negatives. Both went to the expensive Atomic. Obviously, the price tag is the first negative. The other negative came whenever I cleared the mask. Water shot up from the nose pocket into my eyes like a squirt gun. It also happened when I gave the slightest puff to get rid of mask squeeze. I played with the strap tension. I fooled with head angle. I pressed down and/or lifted on the mask in different ways. After fooling around for a while, I found that I could clear the mask without getting squirted in the eye by more or less shoving it down over the bridge of my nose and pulling out a little at the bottom. I still had to crank my head back much farther than any other mask I've ever used to get most of the water out. I couldn't get that last bit of water out of the nose pocket, which normally doesn't matter at all to me. In fact, I normally like to leave a little water in the mask to clear the fog. However, in this case it means that I still get a squirt of water in the eye when compensating for mask squeeze. I didn't have any trouble at all clearing the DGX mask and I didn't have to go vertical and look to the heavens to do so.
I wholeheartedly recommend the DGX Ultra View Frameless if it fits you as well as it did me.
The Atomic Frameless 2's fit and finish is excellent. It's a good looking mask if that means something to you. If it fits around your nose where you won't get squirted in the eye and you can find it 50% or more off msrp, then I would recommend it too...but only if it fits you better than the DGX!
