Sizing Information

The Heat Tech Vest is designed as a mid-layer and therefore it has a more snug fit than typical jackets. It has a fit very similar to Alpinestars race fit jackets which is to say they fit very snug and are meant to fit skin tight. Most people will be able to wear the size they normally wear in men’s clothing, but because of the very close fit, we recommend you measure your chest and belly and use the size chart below. The vest does have some stretch material on the sides so you will have a little flexibility from the number provided.

Our Two Cents

The Alpinestars Heat Tech Vest is part of the new Heat Tech line which also includes several glove models.

The Heat Tech Vest has a power button at the waist or you can connect it to the Alpinestars Heat Tech App to turn it off/on and control the temperature. The App also allows you to see the battery life remaining. A neat feature of this vest is that you have the option to use the included battery, or you can use the included cable which uses a DIN Hella plug (fancy name for cigarette lighter) and draws power from the motorcycle.

I like the versatility this power combo offers and the vest seems to warm up enough on the battery to keep you warm if you’re wearing a quality outer-layer jacket over the top. The instruction booklet makes a point to not use the vest if it is wet, so be sure you have a waterproof layer on over it if you expect inclement weather. The heating elements are on both sides of the chest, the lower back, and the upper back near the neck. The maximum heating temperature is 60°C/140°F on the highest, Red setting. The vest has 3 heating levels denoted by the color on the power button. Red is the highest, followed by Orange and finally Green. A quick press on the power button cycles between the heat levels. You can also set the temperature in the app by sliding or using the +/- buttons but the setting is actually a percentage and not temperature. So I am just guessing that 60°C/140°F is 100% so if you do a little math you can probably find the temperature percentage that you want to set it at. For Fahrenheit ((Desired Temp/140)x100) or if you use Celsius ((Desired Temp/60)x100).

I like the asymmetric zipper style, it’s just offset enough to not line up with another garment so you don’t get a stacked zipper pooch. The fit of the vest is about as expected and the stretch panels help if you’re close on size. It’s designed to be worn tight on a base layer (t-shirt or other) so the stretch is meant to keep it tight on the body so it doesn’t interfere with your outer garment.

I think Alpinestars has done a good job with their first toe-dip in heated gear. They’ve made some innovative changes by adding the choice of using an app to control it, and the dual power option makes the vest versatile enough for on or off the bike use. :: Mike, 03/07/22
