The X Max is a really good looking pair of goggles that comes with a spare lens and features Salomon's Twin Lock System, and it has a noticeably wide field of vision as a result of the very slim frame - this will suit both large and medium sized faces, which makes the X Max quite versatile in terms of fit.
The Twin Lock System is not as fast and easy to use when changing lenses as, say, that of the Dragon NFX 2, but it is quicker and easier than Nike's Fade; however, you'll need to take your gloves off to use it and chances are you'll end up with a fingerprint or two on the lenses (easily cleaned off with the soft carrying pouch that comes with the X Max).
The triple-layer face foam is a lovely, soft double-density version with a quick drying 'velvet' layer against your face to keep your skin dry, and thanks to its softness it adapts precisely to any shape of face, making the X Max among the most comfortable pairs of goggles we tested.
Fogging isn't a problem due to Salomon's 'Airflow System', which balances the inside air volume of the goggles with the flow of fresh air, thus keeping the inside lens dry and fog free, and since the lenses are also anti-smudge, anti-scratch and water-repellent you can enjoy excellent vision unless you wipeout and fill them with snow.
However, all this good stuff was somewhat spoilt by the fact that the lenses on the model we used just wouldn't lock into the frame securely and kept popping out along the top of the frame, so you'll need to double check this if you're looking at buying a pair.
This was hopefully a one-off on what is otherwise a very good, albeit expensive, pair of goggles...
