Will these last if they are being used regularly on tow ropes?
If by tow rope you mean no handle and it's just holding onto the metal braided rope....then you should buy a roll of duct tape. In my years no glove has held up to the metal braided tow rope...unless you use duct tape!!
John- if I were you, I would get some of those leather rope tow guards. It's the only way to keep your nice gloves nice.
