The officials on the Senior List are being provided with new kit from the Adidas 24 range. The SFA have initially decided on Black, Red and yellow. The current mint green and purple from the Adidas 22 Range are also being retained for next season to give five colour options.
It is worth noting that there is no requirement for any referee that is not on the senior list to wear a specific version of a shirt so you are free to buy whatever you wish. The only difference between the black shirt 22 and 24 is the removal of the grey stripes/collar which is hardly a noticeable change. The red/orange is a slightly different shade. The biggest difference seems to be in the yellow shirt which is a good bit darker than the current version.
