the various shops always have diff models and only carry a few
niah..
for backpack, must carry the ones selected so to make sure it
fits comfy..
it's very personal cos we are going to hug, carry, lug it for 3
weeks...
yah, so just try them out lor. the shops usually carry the same
few brands so it shouldn't take you very long.
unless you want the milspec stuff which is only carried by
specialty stores.
but the milspec stuff is damned good sia. my blackhawk pack
which is 6 years old still looks brand new, despite having been
beaten and thrown about, including dunking in sea water.
