ASA is softball so it doesn't matter whether the item is approved by ASA. This is a baseball forum and NHFS says no to artificial bat warmers. Yes, Rich, it is alright to let your metal bat warm in the sun - just as it is okay to sit on your bat to warm it up.
Of course, real bats (wood) do not need warming up!
