Scrum cap
A simpler alternative to a cap, or a head-cap and used by many players, is a thin strip of foam or cloth and electrical tape wrapped around the ears like a head band.This is intended to protect from cuts and head injuries that can occur from incidental contact in tackles or at rucks.[4] World Rugby has not made scrum caps compulsory, and many players and officials are divided over their utility.Former England captain Mike Tindall criticised their usage by youth players, saying that they had a detrimental result on tackling ability from an early age.[5] Welsh player Jonathan Davies similarly felt that they should not be compulsory, as injuries were part of the game.
