The lightweight yet resistant RSR 10 adjustable retention system provides perfect personal fit. thanks to its wraparound structure and multiple micro-metric vertical and horizontal positions for the size adjustment.

In-Mold technology allows us to cast the external polycarbonate outer shell directly during the injection stage of the expandable polystyrene (EPS) impact-absorbing foam. The result is a much more rigid structure which is knock-resistant and extremely light, allowing for better ventilation system. The combined action of the EPS structure, the polycarbonate cap and exo-skeleton creates resistance to the mechanical action exercised by an impact and dissipates the energy in order to prevent it from being transferred to the head of the person wearing the helmet.
The airframe frontal padding minimizes the sweating process inside the helmet enhancing the air circulation and avoiding the release of unpleasant smells and ensuring the best level of performance.
Just replaced my Sterling helmet with this one. Can’t be happier. I’ve had 3 Sterling helmets over the years and it was time to upgrade. Looks great and light weight. Feels faster. The only thing is that I wish it had the mesh net lining to keep the bugs, bees and pebbles out. The fit is good.
Beautiful helmet. Perfect fit. Highly recommended!
I had an Cannondale helmet. I used this helmet new on 70.3 IM and felt the difference. Good fit light keep head cool. Even improved time.
I used it the first time at 66 miles Bike-a-thon in Philly. They were comfortable, covered lots of my face and super stylish.
I recently had a horrific accident where I went entirely over the handlebars, landing directly on my head and the left side of my body.
The impact was severe enough that I broke my collarbone in two places and fractured a couple of ribs. However, despite my head bouncing off the pavement twice, I walked away with absolutely zero head or neck injuries. No concussion, no trauma, nothing. The helmet took the entire force of the blow so my brain didn't have to. Looking at the damage to the helmet, it’s clear that it did exactly what it was engineered to do.
I do a lot of EMTB in Mammoth Lakes and there are loads of tall trees. Light comes and goes and with the Defender's the lenses changes so my visibility is always good. Something I think is important when riding.
