I had an issue with my gloves, the right hand little finger didn't seem to be waring correctly. I bought the gloves in 2012, saw they had a lifetime warranty, so sent them back to Gerbing yesterday. Today I got an email, apologising for the inconvenience and confirming the right pinky of the glove was showing 12 degrees less heating than the right. So they are replacing the gloves with a new set. Bloody hell great customer service and nice to see a company stand by their products.
