Travel gear.
The Travel Store. in KLCC shopping mall mostly sell bages and stuff but have a few dry bags called 'SPLASH PROTECTOR'. which is the worst name ever and probably tells how water proof they really are. But was open.
Other stores i went to but where closed (mid day on a Saturday WTF?) they looked like they had a wider range of camping gear.
Evergreen adventure in Campbell Complex shopping center they have a few stores around. Also a small bike gear shop on the bottom floor.
Outdoor center. A bit of a walk from Ampang Park station (more of a walk since it was closed).
