As cricket is something of a minority sport in Hong Kong, cricket gear is available in relatively few shops here. Note that cricket gear is relatively expensive in Hong Kong; at least some players prefer buying gear while on overseas trips.
Two of the main cricket gear shops are very close together, in Far East Mansion, 5-6 Middle Road, Tsim Sha Tsui: Montgomery Sports and Golden Sports.
Online options maybe also worth considering; though of course, you can’t handle products – such as playing shadow strokes or even whacking a ball with a cricket bat.
BatsandBall is a store based in Hung Hom. While the physical store is – reportedly – not in a conveniently reached spot, it has a strong online store, perhaps with occasional good deals.
Networld Sports is UK based, but has a website for Hong Kong; seems akin to budget option, especially for [own brand?] Fortress gear: Cricket Equipment.
Cricket Direct bills itself as “The world’s finest online cricket store”, and while also UK based has a website that readily shows prices in Hong Kong dollars, and can ship to Hong Kong.
Cricket Store Jakarta would also be happy to supply to Hong Kong; along with international brands, they have their own AK Grains and Garuda brands, made to their specifications in India. You may need to message to check shipping costs. [Note from Martin: I went to their store a couple of times during a holiday in Indonesia in August 2024; bought a few items including AK Grains bats for my son David and me. Friendly staff, even gave us some discounts without being prompted! – seem keen to promote their relatively new brands.]
