Better Fitting Gear

Experience Better Fitting Gear

All Aerostich suits, jackets and pants are produced in more than forty graded sizes (while S, M, L, XL gear comes in only about eight). Graded gear in ‘short’, ‘regular’ and ‘tall’ always feels, fits, looks and works better. And if it’s made well, it will wear longer, too. All sizes are in stock at our headquarters for try-ons and fittings, and there’s plenty of off-the-rack and special sale priced gear here, too. This summer, come in and try it on!

Custom fitting and sizing experts are on hand to provide fit services, too. (Click here to schedule an appointment time in advance.)

Online Sizing Tool


When ordering by phone or online you’ll also be fitted perfectly, too, almost every time, and if a sizing exchange later is needed, your gear always ships free...and fast. But with in-person sizing, you can compare our various suit styles and try all of our gear on.

Visit us and try on an R-3, Roadcrafter Classic, Darien, AD-1, or Falstaff. You’ll feel the difference in comfort and fit that graded sizes provide. For a limited time, everyone who comes to be fitted in person gets a 5% fitting discount! And the free factory tour, too, if you’d like one.

How to Get a Functional, Comfortable One-Piece Suit Fit:

Start with your height and body length…For a person’s given overall height, some will have longer-bodies-with-shorter-legs, and others have shorter-bodies-with-longer-legs. After a suit is sewn and completed there is no simple or cost-effective way to then make the garment’s torso length (the distance from crotch to collar) shorter or longer. A few specialized alterations can help slightly (see 'ellipse' below), but they are imperfect Band-Aids.

Garage mechanics and others who wear coveralls for a living know a lowish crotch and baggy seat means they’ll be able to raise their arms upward fully and comfortably. When one does this arm-raising to horizontal, the entire torso section of a one-piece suit slides upwards about 1.5". The suit’s bulky shoulder impact armor move it that way. And when you lower your arms, the suit body area should slide back downward smoothly.

Aerostich gear is graded by chest size (38, 40, 42, 44, etc) and each is available in short (S), regular (R) and long (L) versions. If you are borderline height-wise, part-way between an ‘S’ and an ‘R’, go with the longer body length of the ‘R’. And if you are somewhere between an ‘R’ and an ‘L’, go with the longer body of the ‘L’. The extra body length in each size is about 1.3" greater. And if you ride a sport bike, or are an especially active rider and want maximum freedom-of-movement, a slightly longer body sometimes works and feels a bit better.

Leg and sleeve lengths should be adjusted as needed after your body/torso length has been determined. For a comfortable and correct fit with your raised arms out to your side horizontally (both at the same time), you should still have very slight room at the crotch.

The suit’s body, sleeve and leg diameters are exactly the same for each ‘S’, ‘R’ and ‘L’ version of a particular size. For example, the dimensions around your body of the 38S, 38L and 38R are identical. The circumferences are exactly the same.

A riding suit’s leg lengths are correct if, when standing normally, the hem breaks (wrinkles) slightly against the front of your riding boot just above the foot’s arch, and the top edge of the TF knee impact armor cup is positioned near the center of your kneecap. Then, as you sit on your bike, the hem will rise about 1.5” and the knee armor cup will slide upward and center itself over your bent knee.

A riding suit’s sleeves are the correct length if, when standing normally with your arms hanging loosely by your sides, they end about mid-way between your knuckles and your wrist, measured at the center back of your hand. The center of the TF impact armor elbow cup should also be centered on, or very slightly below, your elbow.

Specialized Motorcycle Configuration Considerations:

For comfort with low handle bars and higher positioned rear-set footrests, all one-piece riding suits will fit better with the ‘Extra Forward Rotated Sleeve’ alterations, and may also benefit from an ‘ellipse’ added to the center of the back. In addition, an ‘expanded knee’ alteration is available which provides slightly more space for knee armor when knees are bent more sharply.

For active off-road riding requiring maximum freedom-of-movement and upper-arm ease, underarm ‘V’ gussets may be added to increase upper sleeve diameter and provide extra room across upper chest and shoulder areas.
