The Stand21 Ultimate series is one of the lightest FHR device to date and is currently used by many F1 drivers. Exceptional ergonomics, geometrics and a lighter weight all combine to give you, the driver, the very best that money can buy.Using all of their 10 years expertise in FHR design and engineering, taking over two years in development, the Ultimate weighs in at just 435g bare (600g including padding and tethers), a full 100 grams lighter than the current top-level device. The all-carbon bodies of these models combine an exclusive resin-transfer technology (RTM process) with a UD monolithic section. That refined monolithic technology has allowed a new design for the unit's arms. Their thickness is greatly reduced (4mm V s 14mm for current models) as well as their footprint to improve the fit between driver and harness.The arched top has been re-engineered and re-designed in its whole, offering a reduction of its physical thickness to below 2mm, allowing a reduction of helmet-to-s
