The 635 from Limar is a tad beefier than the company's Ultralight 777, but there's very little in it, just 10g or so. It's designed to be a cost effective performance lid, and the company has an impressively rigorous set of safety certification attached to all its helmets, including the US CPSC standard and the even tougher Australian safety certification.
Italy's Limar are best known for their helmets but they do a whole range of eyewear too, including these practical specs at a mid-range price that put in a fine performance.
Limar is known for its ultra light helmets with the range topping and does-what-it-says-on-the-tin ULTRALIGHT claiming to be the lightest lid around. The 777 continues this trend coming in at a very competitive 243 grams for the large size tested. All this at the (cheap by today's standards) price of £69.99, surely there's some kind of catch?
Limar's £104 Pro 104 Ultralight helmet got a good write-up recently from road.cc's Roger Blessed. This 575 Sport Action will sting you for a much more humble £39.99 but still carries over some of the features of the Pro, such as the in-mould construction and the dial adjust headband. That dial makes it a cinch to secure and the L that I tested was a pretty good fit on my (large, round) melon. At 270g it's reasonably light too.
This low-profile lid from Limar is extremely lightweight – 187g, to be precise. That’s even lighter than the manufacturer’s claimed 200g for the large size, and safely inside the ‘so light you can barely feel it’ range. Your highest priority might not be to trim off grams when it comes to protecting your head, but the 104 passes all the safety regs, so who are we to argue?
