I read others reviews and ordered a size up from usual and hoped for the best. He was very happy with them and said they worked great! I am so impressed with these Bengoo headphones! Without hesitation a new cord was offerd. I even went to Canadiantire to buy the bolts. This hat is lightweight and breathable yet gives great coverage from the sun. I reached out to the manufacturer but never got a response back. I love under armour but these are not true to size! Basically had to tape the liner to the new piece as it is not a perfect fit for the rubber liner. And a great price (~$11) - cheaper than what I found elsewhere.
