【Safety】 MET's road bike helmets ensure rider safety with high impact absorption performance while being lightweight. This was MET's top-of-the-line helmet at the time. Recommended for those who like the classic, pointed-back style! ◆Description MET Model: SINE THESIS Retail Price: ¥29,970 (excluding tax) Size: L (58-61) Includes dedicated case This is a used item, so there are some scratches. There were no inconveniences during use, but some fixing parts are missing (around the 4th photo). Please understand this before purchasing. ~From the introduction site at the time~ "The ultimate flagship model pursuing cooling performance MET, which has been actively working on cooling performance inside helmets, has created the ultimate flagship model "Synthesis" with a completely new approach to cooling. They have acquired three patents: ICE lite, GEL O2, and HCS20 to further improve the cooling system. ICE lite, which creates maximum openings by arranging very thin, transparent ribs that you can see through in the air intakes; 11 GEL O2 micro-pads placed to suppress sweating; and HCS20, which has the concept that less than 20% of the helmet contacts the head thanks to those small pads. Past experience and these new technologies ensure unprecedented cooling performance, as well as lightness and safety." ※Cancellations are not possible to prevent switching. Thank you for viewing.
