Designed with the same anatomically optimized fit that Alpinestars suits are known for.


Replacing the budget priced Delta, the Alpinestars Stratos racing suit offers a protective 3-layer construction without any weight penalty. Certified to SFI 3.2a/5 fire resistant standards, the Stratos is designed with the same anatomically optimized fit that Alpinestars suits are known for. The shiny outer layer gives the suit a vibrancy that isn't generally found at this pricepoint, helping make sure sponsor logos are extra visible. Driver comfort is improved with stretch panels through the arms and back, along with pre-curved arms and legs to enhance mobility. Extended, full-float shoulders provide a relaxed fit, while boot-cut legs provide a classy look.

Alpinestars Nomex Suit Sizing Chart

Sizing Tips: A Driving Suit should have a loose, comfortable fit and allow for a full range of motion. Make sure the fit doesn't change when sitting down! A suit that fits tightly may sacrifice the protective layer of air between the suit and your skin/underwear and can potentially decrease the level of protection provided by your suit. Driving suits do not "break-in" or stretch over time. Note: Waist & Pant sizes are included for reference only. Make sure to double check all measurements! Your ideal size will be the smallest size that includes your largest measurement below:

A. Chest: Measure around the fullest part, under the armpits, keeping the tape horizontal.
B. Waist: Measure around the natural waist line, inline with the navel.
C. Hip: Measure around the fullest part of your hips, about 20cm below the waist line.
D. Inseam: Standing against a wall, measure from the crotch to the bottom of your leg.
E. Arm Length: Measure from shoulder to wrist.
