if you are not planning to camp in extreme weather, then the cheap stuff from decathlon is actually pretty decent. of course you could still get better quality items so that they last longer/more comfortable/bigger but some stuff are really just expensive because of the brand.

malaysia weather dont need the expensive 4 season tents. Any normal tent would do fine imo. Vidalido or kzm or coleman all more or less the same unless you're looking to flex on the campgrounds.
