When youre looking for a performance helmet no doubt weight fit & ventilation are at the top of your list of priorities. The Endura Airshell ticks all of those boxes & more. The use of glass fibre/carbon fibre bridges (depending on colour of helmet) reinforces the structure of the helmet which means that it can be made lighter whilst still exceeding the CE safety standard EN1078:2012. The S/M sized Airshell tips the scales at a featherweight 230g so youll hardly notice that its there. The reinforcing bridges also allow the Clear Thru air vents to be larger & the Head Stream internal channeling to be deeper which work together to maximise the flow cooling of air over the helmet. The fit is highly tuneable & adjustable to offer great levels of comfort. There is a dial fit system which allows one-handed micro adjustment & also has three height settings to suit the individual riders fit. The padding inside the Airshell is also very soft & comfortable with quick wicking properties as well as an anti-bacterial treatment. The padding liner can be removed for washing too to keep it fresh as a daisy. Further to this the fit can be tuned further with the adjustable strap system. The Airshell is covered by Enduras Crash Replacement Policy & Endura Product guarantee.
