Alpinestars SG-1 Two Piece Race Suit
Sizing Information:
The suits are offered in European sizes, so you can select the size using Alpinestars sizing chart using your chest and waist measurements. If you have a bit of a belly, please also measure and compare to the following table. Make sure you are selecting a suit size that will accommodate your chest, belly and waist (from the Alpinestars chart). Height range for a 2pc suit is a bit taller than in a 1pc suit, so if you are a bit taller than average, this style is a good choice. Estimated maximum height for this suit: smaller sizes about 5’10”, for mid-size suits about 6’, and for the larger suits about 6’2”.

The emphasis for the SG-1 suit is ventilation. A very good portion of the front of this all leather race suit is perforated leather. And these perforations extend down a portion of the thighs as well. The perforations in the leather are larger than in most Alpinestars gear, so the air flow should be pretty good. A 2pc is a great choice for sport street riders and amateur track riders. The construction of a 2pc suit allows you to detach the jacket from the pants and wear it separately. And when you want to wear the pants, say for a track event or sport riding, just zip the pants to the jacket with the full circumference zipper and you’ve got a full race suit style. This suit’s overall construction and features are excellent for a suit in this price range. The shell is made of thick, high quality cowhide. The protectors in the shoulders, elbows and knees are a CE rated type that are very substantial. This type armor is constructed of hard plastic over foam which is the type offered in most high-end race suits. There is also foam armor included for the hips and there is a foam back pad included. The suit also comes with knee sliders as standard (which saves you about $40). Take the “View Larger Pictures” link above to see some good close-up pictures of the suit and its features.
