Goggles with interchangeable lenses are a boon, but it's not always as easy as it might be to actually change the lens - unless you're using Dragon's brilliant Swiftlock Lens Change System
The easy on-and-off mechanism uses a pair of small, locking levers integrated into the goggle frame - you simply flip the levers up to release the lens, pop in the new one and with one quick motion, lock it down.
It's so easy you can more or less do it with gloved hands, and it makes you wonder why some other lens change systems are so fiddly in comparison.
The cool-looking, frameless NFX2 comes with a spare lens, and each lens has an optically correct cylindrical design, which provides optimum peripheral vision - that said the goggles are not especially large and you may find peripheral vision is not as good as it could be if you have a wide face, so check before you buy.
Fogging isn't a problem thanks to the combination of a super anti-fog finish on the lens and Dragon's 'Armoured Venting' system which prevents snow that may get into the vents from working its way onto the inner lens.
Other features include 100 per cent UV protection, soft, triple-foam hypoallergenic micro-fleece lining, which feels great against your face, and, of course, they're helmet compatible. Oh, and you also get a sturdy carry case and cloth bag.
