finally decided to check out one of the "real" Decathlon stores - and since there was one in Joo Koon, and was easy to get to (next to the station) i decided to go there and .. holy shit it was huge! PP said that wasn't even the biggest outlet.

i did managed to get what i needed - a small pouch, and a running vest that could be my new "bra"  (that would fit my mobile)
