The Octal is a game changer in road bike helmets due its unique fully wrapping unibody construction combined with old-school looks and a light 250 gram (medium size) weight well below its competitors flagship models. Many may recognize the POC Octal helmet as the choice of the Boulder, Colorado based Garmin Professional Road Cycling team. Others may be familiar with the POC name from POC's snow sport roots. Mountain bikers have flocked to POC's Trabec as the "Dad's helmet" for those wanting the best protection again falls.
POC created the Octal to provide more coverage and additional protection for the temples and back of the head. It has a definite feel of being a little more around your head instead of perched on top. To further improve safety, the EPS liner is strategically thicker in most exposed areas and is covered by the outer PC shell. The unique and fully wrapping unibody shell construction functions as a monocoque and enhances the safety properties and construction integrity of the helmet while maintaining a low weight.
Other features include a very refined adjustment dial that can be easily operated with one hand. Speaking of refinement, the straps emanate form the shell for a very clean appearance. Coolbed padding actually works to regulate temperature. POC has even included a specific eye garage for sunglasses with a tacky rubber/plastic material that ingeniously holds your valuable eyewear firmly in place.
Just purchased this helmet, the fit is really nice for me, I purchased a medium and there is still room for a hat inside the helmet or I can easily just tighten it down to my head. The adjustment works great. The straps are nice and light. The helmet is the lightest I have owned. It did interfere a little with my Sunglasses. However getting the sunglasses on and helmet set on or around them it works fine. I hope to never be able to comment or review the safety aspects but their safety claims were a factor in my choice to purchase.
Pros: light, comfortable
