Nice helmet

Comment: This helmet is well constructed and feels solid without being heavy. The integrated visor is nice for keeping the wind out of your eyes but would be better if it came down about 3/4" to 1" further. I would prefer if the chin strap had a snap to keep the loose end from flapping around, but it is easy enough to tuck under so that is a minor complaint. Overall I like the helmet and would recommend it. The sizing chart is off. I measured my head at 23 1/2 inches which is the low range for a L. That helmet was painfully tight and the XL fits comfortably snug.



Great Helmet

Comment: This was a great helmet and looks really good also. The flip down shield is very useful when you wear glasses.


Richmond, Va.

GMax GM55S Carbon Helmet

Comment: I read most of the reviews for this helmet, so I thought I had a clear idea of what's coming in the box. The helmet is nice. Pros: Looks, Finish. Price. Cons: Visor too short (needs another .25-50" to it to be effective). Helmet must be moved forward on the head for the visor to not interfere with vision zone. Strap doesn't have a quick snap on it, so you have to fiddle around with the flimsy red elastic band to secure your strap. Overall a good deal, but I'll never buy Gmax brand again if this helmet is indicative of their functionality.

GMax GM55S Carbon Helmet Review

Comment: I bought this helemt for riding around town when the weather is hot. This helemt fits me correctly, and has great air flow for cooling my head. The drop down shield is too short, and the wind gets up inside the shield from the under side. The elastic keeper band for the strap is not a good design. A strap snap would have been much better. This is a good looking helmet that fits well for the price. Size chart indicated XL based on my head measurement, and the XL was too big. Exchanged for a large. Jafrum turned the exchange around quickly. Great service.

GMax GM55S Carbon Helmet Review

Comment: Nice lightweight helmet, retractable shield is really handy. Fits head nice & doesn't look dorky. Granted Jafrum offered exceptionaql price but should advise product may have cosmetic damage. Mine arrived with chip in clearcoat finish on top front. Figure it's pre-broken in.
