1. Low side tested low side approved
I wear a size L Tech Air 5 under a AlpineStars GP Pro V2 size EUR 56 with altered sleeves and leg length. I'm 190lbs 5'9" 101cm chest and a bit of a belly.
Low sided turn 7 at NJMP Lightning yesterday. I couldn't tell you when it deployed but it worked a treat. I rolled four times on a cloud, shook the dust off, and got back on the bike. Without the air bag suit I definitely would have had injury to my back and sides and might not have been able to ride off and continue the rest of the event. Feeling some soreness the next day, nothing unacceptable. The fact I have to send it in for weeks to be repaired is the ONLY downside, and why I'm buying a Tech Air Race as well as this unit. I'm converted to airbag suits and never riding without one again.
The app can be a problem on SOME Samsung phones. AplineStars needs to resolve the issue, I never got it to work reliably with the S10+, but on an S9 and my S21 Ultra it works perfectly, allowing quick changes between race and street algorithms, firmware updates, and even ride tracking if you are able to keep your phone in your suit pocket close to the bluetooth unit in the Tech Air 5.
