As a commentator (Lloyd?) said yesterday, the players need to be kept warm in the early English summer, and these new threads don't look like they'd do that nearly as well as the traditional sweater. In fact, it could have a negative effect, as in order to keep warm they'll have to keep more active, which will cause them to tire more quickly.
Okay, so the last part may not make that much of a difference, but they're godawful anyhow.
If enough of a stink is raised, then hopefully the traditional sweater will return when the current contract expires. I hope so, anyway, becuase the sweater
is English cricket.
