Pros: GPS unit, ease of use, comfort
Cons: Odd fit, cuts into peripheral vision,
Saw these when they first came out and wanted them but couldn't justify the price. Managed to find a returned unused pair last year at a deep discount and since I was planning to get a new pair of goggles, I splurged and got these. Read reviews and the biggest gripe was the odd fit and it seems to be true but I wear these with a helmet so could be either.
Got to try my first real use in them earlier this month for a week at Copper. Had everything from bluebird days to snow and low light and even in trees. I have the ones that are SPPX which have the polarized photochromic lens. Only time I really had an issue seeing was in complete flat light. I've yet to find any goggle that can help out in these situations. The tint is a bit slow to change but this didn't bother me while skiing. It adjusted quickly enough to help during skiing, just don't expect it to change right away when going from sun to shade. Since we were inside for lunch, they became almost completely transparent and took several seconds to adjust when I walked out.
The odd fit I mentioned isn't unbearable or uncomfortable, it's just that the nose piece tends to rise a bit. This has lead to flakes getting under a few times when it's really coming down and cuts off the right 1/3 of the display for me. My Oakley Crowbar goggles let in air and snow in as well at times no matter how i adjust them so I've just learned to live with it. After an entire days of use, the Zeal's were still comfortable and didn't bother me. I did not have an issue with fog at all from these goggles.
The one thing that did require getting use to was that the computer chip and display cut into my side view. It almost felt like looking out of a window and seeing the frames on the sides and it did take some time to get used to. I swivel my head a lot, learned from riding motorcycles, and made up for this but could be a dealbreaker for some people. Not sure if the Z3 goggles resolve this issue or not.
Battery life is great. Temps ranged anywhere from -1 to 32 throughout the week and was on the mountain for most of the time. Had two days of being there from open to close and when i finished, the battery indicator was showing read but still worked. Some of the colder days saw its battery almost dead after 5 hours of riding. I do turn off the display while riding and shut the goggles off during lunch.
The display itself is well out of the way and non-intrusive. As mentioned, it does have the right 1/3 cut off while riding but I just have to press in the nose piece to view it all while on the lift. Newer Z3 is supposed to fix this with an adjustable display from what I read. The main screen is customizable and mine shows speed, total vert ft, and time. I had temp on there but it ran anywhere from 10-25+ degrees high. Had a 25 degree day at the base and the goggles were reading around 52 degrees. Great in theory but poor execution. OTher stats are total runs, number of days on the slopes, total distance, total vertical feet, last run vert ft, last run distance, top speed (overall and last run), ave speed (overall and last run), coordinates, run time, and jump stats (time in the air, length, hieght, and total ft).
Memory is supposed to have enough for 4-6 days but I have 9 days on mine and still showing 22% free. You can upload stats to the Recon site and view it all later. It even shows you the runs you did laid out over Google Maps on the resorts. There are some errors but it's fairly accurate overall. One thing that bothers me is that you can't see total run stats for the day on the site and it's all in miles, not feet, meters, or kilometers. I haven't found a way to change this. Also, you can't overlay all the runs together on the site, you can only view them one by one. Another oddity is that during two days, rather than regulrly shut down when I was trying to power it off, it just turned off and cleared my stats. It remembered all previous day stats but cleared out everything that it recorded from earlier that day. It only happened twice but did clear out some of my runs in the bowls.
overall I really like the goggle. Couldn't justify the MSRP price but if you can find a great deal on them, I say go for them. Do try out the fit if a store by you has them as they are a either love it or hate it fit by everything I've witnessed and read. If you can, spend the extra on the photochromic lens. It may not be perfect but it's great feeling not having to juggle between different goggles or lenses on the mountain.
