Thanks sa tanan ni reply i highly appreciate it. Most of the bags u suggest me are backpack types. But these won't fit me kay magdala pa man gud ko sa akong trekking backpack where i put my clothes and the rest of my climbing gears. Another thing if i put my camera inside the backpack, anyone who would experience climbing or trekking would know how troublesome it is to put down the backpack ang get the camera to take a shot. Imagine imo na buhaton for the entire length of the expedition. The Theory is once you put it in your pack imo na jud na ma habwa inig abot sa basecamp kay kapoy na man gud cge kuha2x while on the move.
