Sena Impulse Modular Mesh Helmet Sena’s all-in-one Impulse Modular Helmet offers up mesh Bluetooth communication, crystal clear audio quality, a drop down visor and an integrated tail light all in one! The Impulse features their latest and greatest mesh Bluetooth technology blended with Harman Kardon premium speakers and an updated microphone for a new level of precise clarity not found in other helmets with baked-in communication systems. This helmet’s integrated Group Mesh Intercom is capable of up to 24 riders in a private group, and the Multi-Channel Open Mesh Intercom mode can support virtually limitless riders. If a big group isn’t your thing and your crew is still riding with non-mesh Bluetooth headsets, the Impulse has that covered via the 4-way standard Bluetooth intercom, as well. As an added bonus, Sena’s Impulse Modular Helmet features a retractable sun visor for swift eye shade when you need it on the go, an impressive 4 vent design for all your cooling needs, and an integrated tail light for maximum visibility. The Sena Impulse ticks all the right boxes for those looking for an all-in-one helmet, with Pinlock insert included, featuring integrated Mesh Communication technology. Note: Customers have found this helmet runs small and recommend sizing up if you are in between sizes.
