Have seen many of the pakistan players use other brands in the past and use stickers from their sponsor to cover up the actual manufacturer of the equipment.
Inzi used to use Kookaburra softs and cover their logo up with the Wills sponsor logo, thats was back in the 90's so its nothing new.
I can understand players using the sponsors logo's on bats so that they fulfill their sponsorship requirements, but what is the point of Akmal using his sponsors labels on equipment which they don't sell. Its hardly promoting the brand and its products
