PRODUCT FEATURES

  • Multiple Riding Modes — The Tech-Air® MX System comes with the default MX Mode that permits the use of the System on off-road tracks, specifically for Motocross riding
  • The System also features two additional Riding Modes ("MY RIDE 1" and "MY RIDE 2"), which can be customized by the User via the Tech-Air® App selecting from the currently available Riding Modes: MX Race, Enduro, and Rally
  • Once the Riding Modes are set, Users can easily switch between them by pressing the Display Button (3) or directly using the Tech-Air® App*
  • MX/MX Race Crash Detection Algorithm — Alpinestars’ MX/MX Race crash detection triggering algorithm has been developed and refined with thousands of hours of riding data and crashes, allowing the System to accurately assess when to deploy the Airbag ahead of an impact or other dangerous situation—fully tested by Alpinestars Pro-riders, in extreme racing conditions, including MXGP, AMA MX, and Supercross training environments
  • Active Airbag Protection — Upon the detection of a crash situation, a protective Airbag is deployed, providing unrivaled protection to the rider with an average inflation time of 40 ms, depending on the Airbag size
  • System Versatility — The Tech-Air® MX System can be worn over or under any properly fitting apparel with enough room to accommodate the inflation of the Airbag in the event of a deployment
  • Single Gas Inflator Deployment — A single gas inflator delivers one Airbag deployment for guaranteed protection
  • After the Airbag deploys, the gas inflator must be replaced before the System can be used again
  • The System has a quick-release cover opening that allows for rapid gas inflator replacement by users, only available in countries where gas inflator replacement by individuals is permitted by local regulations
  • Battery Life and Charging Time — The Tech-Air® MX System uses an integrated, certified lithium-ion battery, with a fully charged battery life of 30 hours and a recharge time of approximately 4 hours
  • Charging the battery for approximately 1 hour will provide approximately 8 hours of riding time use
  • Quick-Release Cover Design for Rapid Gas Inflator Replacement — System Activation/Deactivation: Activating the Tech-Air® MX is easy; simply attach the left buckle of the System to the Chest Protector, and an internal magnetic switch will detect the left buckle is closed and automatically turn on and activate the Airbag System
  • Removing the left buckle will automatically deactivate and turn off the System

System Specifications

  • The LED Display is integrated in the Chest Protector to monitor the System’s status and battery level and provide convenient and easily accessible charging for the System via a USB-C connector
  • The LED Display also incorporates the Riding Modes LEDs allowing users to easily switch between Riding Modes
  • The vest is constructed from a breathable stretch mesh for superior ventilation with a streamlined, low-profile and lightweight construction, keeping the protection close to the rider’s body to maximize comfort and freedom of movement
  • Convenient and easy charging of the System, simply plug the USB-C cable into the Recharge Port on the System’s LED Display and connect to a power source
  • The back protector incorporates Alpinestars Nucleon Plasma technology which is ultra-lightweight, flexible, and highly ventilated for enhanced performance, protection, and overall rider comfort
  • Chest protector built from premium materials combined with an innovative design, utilizing both honeycomb technology and Polyhedron Cell Technology to create a passive protector that is highly ventilated, lightweight, ergonomic, and robust
  • No external sensors are required for the System to operate
  • Robust internal housing located in the built-in CE-certified Nucleon Plasma back protector accommodates the System ECU and gas inflator
  • The Tech-Air® MX’s ECU is seal-protected within the System to ensure all-weather performance; the System and componentry are certified to function between -10°C and +50°C
  • The Tech-Air® MX System’s Electronic Control Unit (ECU) and Airbag are completely removable so that the Protectors can be washed separately
  • Users can easily update the System’s firmware when improved crash-detection algorithms are released directly in the Tech-Air® App
  • The ECU has been homologated to ECE R10 04 which ensures the unit’s electromagnetic integrity and stability
  • Bluetooth connectivity to the Tech-Air® App means the System’s operational status, battery status, and My Ride Trip recording can also be easily accessed on a mobile device

Protection

  • A fully self-contained, standalone system; 3 accelerometers (1 triaxial accelerometer) and 3 gyroscopes (1 triaxial gyroscope) are integrated in the Electronic Control Unit (ECU) to provide the best crash monitoring performance and active Airbag protection for a variety of dynamic MX riding scenarios
  • Average inflation time of 40 milliseconds, depending on the size of the Airbag
  • Increased Airbag coverage on the chest, back, and shoulders provides effective upper body protection
  • The Airbag is certified for up to 6 Airbag deployments before having to replace it, provided the Airbag hasn’t been damaged in one of the first 5 deployments

Riding Modes

  • MX Mode is recommended for Motocross use, i.e. on outdoor tracks with natural, uneven terrain, such as dirt, sand, mud, and rocks
  • Typically, these riding scenarios include obstacles like jumps, berms, and ruts and features long straights, sharp corners, and uphill or downhill sections
  • MX Mode can also be used for Supercross riding, that typically consists of riding on indoor or stadium-based tracks that include tight corners, large and sharp jumps, and man-made obstacles like whoops and rhythm sections
  • The System function for MX Mode is accurately optimized based on riding, falls, and crash data coming from the use of the System in this context
  • The MX RACE Mode should be used under the same conditions outlined in the Tech-Air® Manual, and the Section entitled: Envelope of Protection: MX MODE
  • Unlike MX Mode, MX RACE Mode is designed for a more selective airbag activation scenario in the event of high-severity accidents while preventing the activation for minor accidents, such as tip-overs, i.e. low-speed accidents where the bike falls over, typically without significant impact or damage to the rider

Warnings

  • The MX RACE Mode is intended exclusively for use in competitive sports events where the rider cannot immediately recharge the System after deployment during the race. In such cases, unnecessary deployments could leave the rider unprotected in the event of a more severe accident.

Pleasantly surprised!
Size: Queen, Style: 2 Dark Gray
I had been searching for a quality mattress topper in hopes of extending the life of our mattress. I compared a few options and kept coming back to this one. I have to admit I was skeptical because the price point was lower than many options. This topper is SO comfortable and soft! I left it laying out for a couple hours and then followed the instructions to put it in the dryer. Worked like a charm. I’ve been going through issues with hip pain and this has made a difference in my sleep and I’m waking up in less pain. So happy I tried this out. The padding is so comfortable and fit on the mattress using the same sheet we had.

So perfectly soft
Size: King, Style: 2 Dark Gray
My husband was complaining about the mattress, and wants to spend a lot of money on a new one like the ones at the Waldorf. I asked him to give me a chance to try to fix it first. Watched youtube videos about hotel style beds, and landed on the need for a mattress topper. This one is so... very... comfortable. I thought the grid pattern would bother me, but nope. You don't realize how much heat you soak up from your mattress until you get a nice airy layer in between. I almost completely stopped sweating at night, and he's stopped complaining about hurting as much. This is another of those items that I'm scared of washing too much, but it's held up with care and caution. If it starts to get a bit too squished, I just fluff it in the dryer and the padding poofs right back up. The sides are deep and my mattress sinks right into the pocket with no pulling. I have bad back pain and I am certain this has been helping support my back a bit better, so I wake up more refreshed. I'm sorta popping out of bed like I used to years ago. He still plans on a new mattress, but this has saved us money, for now, and when we get the new one, this will layer on top like a dream. I'm glad I took the chance on this, it has really improved our rest, and that's so important.

Cloud like plushness without loss of support
Size: Queen, Style: 1 Green
Cloud like plushness while not losing support. Bought a new high end plush mattress and adjustable bed frame with massage and still wasn’t feeling that cloud like feeling that I like. I don’t like foam toppers because it is too soft and it lacks support. This topper fit perfectly on a 13” tight top mattress over the protector. The topper was exactly what I was looking for. So comfortable, cool, and put me to sleep right away. Massage feature on adjustable base feels the same as it did without the topper, but the bed is just more comfortable and hard to not want to be lazy in it all day now. For the price, this can’t be beat. If you’re looking for a mattress topper to enhance the comfort of what you already have, buy this. You won’t be disappointed!

Very, very soft and cushiony that I can feel even thru the fitted sheet .
Size: King, Style: 1 Green
Very well packaged. Box was very heavy, but once I got thr shrink wrapped package opened, it inflated on its own. It is a perfect fit. Although it isn't thick, it is extremely soft and my back and hip feel better (arthritis and sciatica). I plan on getting a memory foam pad to put underneath, but for now, I am reasonably pleased. The quality was so good, I decided to keep it instead of going thru the trouble of repacking it.
