When buying a hockey jersey, it is important to find the right size to ensure a comfortable fit. Here are some tips from the search results to help you determine what size hockey jersey to buy:

• Try it on: If possible, try on the jersey at a store to get a better idea of how it fits.

• Measure yourself: Use a tape measure to measure your chest, waist, and hips. Compare your measurements to the sizing chart provided by the manufacturer.

• Consider layering: If you plan to wear shirts or other layers under your NHL jersey, you may want to order the next size up.

• Order one size smaller: For Adidas jerseys, the NHL recommends ordering one size smaller than what you normally wear for everyday use.

• Room for equipment: The right hockey jersey size is roomy enough to fit loosely over your shoulder pads or chest protector.

It is important to note that sizing may vary depending on the brand and style of the jersey. When in doubt, it is better to order a size up to ensure a comfortable fit.
