Was head butting concrete walls and it works!

After less than 3 years of kind use (wash periodically with gentle soap, transport in soft cloth bag, etc), the fit system on the back of my Synthe helmet has snapped. Also, the finish is a combination of gloss and mat, but the mat finish is peeling, I suppose from sun exposure, which is a little ridiculous, given that my head is almost always in the sun when riding...

Pros - this helmet fits me great and is comfortableCons - poor ventilation and sweat managementThis was bought to replace an original Giro Synthe which was a great helmet. The Synthe II fits my head great and is very comfortable on long rides. However it has little ventilation and so runs super hot and my head sweats buckets when I wear it, even in the depths of winter. It also has no sweat management system sweat streaming down my face once the forehead liner cant hold any more.This helmet is great as it is comfortable on long rides, but I wont be wearing it when summer rolls around.

Very happy with this helmet. The dial adjustment system creates a great fit, with (importantly) enough room for my ponytail.
Nice Helmet, easy to adjust, easy to clean, comfortable
Another great Giro. Their small fits my pin head, the fixing system work well and is well ventilated. Got at in a sale so at almost half price - bargain.
