The Atem V4 suit represents further development on a range that reflects the technology and experiences Alpinestars has accumulated over the years, in both MotoGP and WSBK!
The suit is stitched in 1.3-mm-thick premium leather combined with stretchy HRSF panels, featuring accordion-stitched leather in the right places for increased freedom of movement when riding. In the most exposed places (elbows, seat, shoulders and knees) you will find very durable aramid threads and extra leather reinforcements.
On the back you will find a Nucleon protector, GP-R protection over elbows and knees, Bio-Flex Racing protection over the hips and RR protection on the shoulders that slides over the asphalt. In other words, well-thought-out protection in places it is most needed!
Replaceable sliders over the knees and elbows.
- 1.3-mm-thick, partially perforated cowhide leather
- Aerodynamic back hump
- Waterproof inner pocket
- Nice microfibre around collar and wrists
- Pockets for inserting Nucleon KR-Ci chest protector (sold separately)
- Shoulder, elbow, knee and hip protection meet EN1621-1: 2012 level 1
- Back protection meets EN1621-2: 2014 level 2
- The garment meets Category II prEN17092-2: 2018 Class AAA
