The nfl jerseys are great. You can wear them on Sundays, or any other day of the year and show team pride. But because they are not your everyday, normal shirts, it can be difficult to figure out what size will fit you properly. There are a number of resources around the Internet that provide size charts for NFL jerseys from a number of different, authorized football jersey producers. If you know where to look, you’ll find that finding the right football jersey size is easy. Step 1 Measure yourself (or ideally, have someone else measure you) in inches from the top of your shoulder to the point where you want the NFL jersey to reach on your body. Step 2 Search the Internet for the team jersey and the brand that you are interested in buying.You can buy Vikings Jersey, Patriots Jersey, Saints Jersey… Step 3 Visit www.cbssportsstore.com/sm-football-jersey-size-chart–bg-1381340.html. It lists the official jersey sizes for both Reebok and Mitchell & Ness jerseys, the two authentic NFL jersey makers. Take note of the "body" measurement for each football jersey size and compare it to your own measurements. Step 4 Order your football jersey from an Internet outlet, or go to a local store that sells authorized NFL jerseys, with the knowledge that you have found the appropriate football jersey size.
