FYI, these hats were available from Vintage Drum Bug, aka Vinny.
Mine just didn't seem right. Kind of "choked sounding" with the stitched vent. Mallet Player2
Needed to be opened up.
Came across some tarp grommets and a tool to install them in my shop.
Free breathing restored........thank you dristan.
And thanks to Vinny, who has great stuff BTW.
He is awesome to do business with.
