The downsides of Tech Air are few but significant. First is cost: Tech Air adds about $2500 to the Race Replica’s $2899 price (the Tech Air suit retails for $4999). The airbag setup also adds 1.5 pounds to an already hefty suit. Another issue is complication. While the technology is easy to use and maintain, things can go wrong. In my case, the magnetic sensor on the collar came loose, so the suit wouldn’t arm until I re-attached the wire with a dab of silicone sealant. Like the sensor wire, the control module is insufficiently secured within the hump. It’s supposed to clip to the nitrogen canisters but pops off given the slightest bump and is free to float around within the hump, making it hard to reach the on/off switch and offering the potential of wiring damage. Lastly, my suit threw a code midway through a weekend-long testing session. The control module has its own WiFi network so you can check the system’s status via a smartphone or laptop, so I used my iPhone to determine that the left-side leg sensor wasn’t working. Alpinestars says the Tech Air system can operate with up to two accelerometers inoperable, so I was still protected, but it’s discouraging to think that my suit has already had several issues even though I’ve only worn it a few times.
