The Universal Side Nets are specifically developed for The Net Return Series (Home & Pro). 
 
The side nets prevent a missed ball from leaving the strike zone. If you use the net indoors, or in a location where balls that are missing are a safety risk, the side nets are necessary.  
 
If you are an experienced golfer or you use the net outdoors where safety is not an issue, the side nets are not necessary. 
 
The side nets can be added to your net at any time and are therefore in principle not necessary to use the net from The Net Return. 
 
The side nets are made of polyester and are attached to the Pro Series Net in less than 5 minutes using Velcro color strips. They can be easily stored in the transport bag of the Pro Series Net.
