This Italy jersey uses the USP technology:



Some information on puma's USP technology:



These jerseys have a unique mesh material on some areas of the jersey (mainly on the front). As you can see below, the front material (on the outside) looks like a net:


In reality, there are 2 separate layers. One is the outer layer (that looks like a net) as shown above, another layer is the inner layer as shown below:



Now.. as jerseyman advised previously.. washing your jersey in my opinion and then ironing it helps to prolong it's lifespan if you tend to wear it.. Of course, the best method to keep your jersey forever is by keeping it untouched.. Then keeping it in plastic covers is another story. But if you want to iron your puma USP tech jerseys after you've washed and spin dried them.. be careful..

Do not:



Why?

Although it is recommended to iron press beneath your jersey's club crest, sponsors and nameset (to enhance the glue bonding) for the puma USP tech jerseys.. there are 2 separate layers.. By doing so (with no cover between the inner and outer layer) will cause the club crest/puma logo that is applied on the outer layer to bond and stick with the inner layer.. This causes the jersey to not function using it's USP technology as optimum as possible (bad ventilation) and it doesn't feel nice... right?

For all.. I mean all puma jerseys that uses this USP technology.. notice on the front layer (bottom half), there is a small gap hole located as shown below:



At first I though that my jersey has a torn stitching on the bottom half (front layer).. but it was actually intended to be there.. Why? So that you can insert into the gap hole (in between the 2 layers) a paper cover that you can use to cover beneath the club crest/puma logo. This gap hole can also be used to insert a cover that covers when you want to print the front number in front of the jersey (for national team jerseys)...
