Alpinestars Atem V3 Race Suit Review and Sizing Info from STG

  • Alpinestars Atem V3 Race Suit Sizing We feel the Alpinestars Atem V3 Race Suit runs true to size as compared to most suits on the market today. At 5' 11" 200lbs with a 32-33 in waist I wear a size 56 Euro / 46 US with a perfect exaple of "Race Fit". This suit shares many of the features found in the Flagship Alpinestars GP Tech V2 suit with a similar fit pattern at a much more affordable price. - Brian Van
  • Brian Van's 2 Cents The Atem V3 Suit is a proper top shelf road race suit with all the features we look for in a premium suit. If you do not have interest in adding the Alpinestars Tech-Air Airbag System to your suit and want a high end suit this is a great option as it gets you very close to the GP Tech V2 Suit and sells for $650 less.
  • Who is this race suit right for? This race suit will be great for racing at any level, track days and performance street riding.
