This is the first soccer scarf I have ever purchased and I must say, it is of amazing quality! My ex-girlfriend was a weaver and she definitely wouldn't be able to weave something as nice as this. Must have collectable if you are a supporter of the US national soccer teams.
This is authentic - good size, good quality - no issues.
The scarf helped us beat Ghana, tie Portugal, lose/win against Germany, but it had no effect on Belgium and all of their evil ways somehow?
Served me well during the USMNT vs. Ghana game, but didn't bring the same results in the following matches.
Nice scarf!
Love this scarf!! Was great for the World Cup and will be worn to many soccer games in the future!
Just the quality I was looking for and speedy delivery! I was very happy with this purchase.
It's awesome and comfortable. Great way to rep your country.
