Hi all, I need some advice. I am a 5'0 tall girl but I like to carry tons of things in my bag with room to spare.. I'd usually use the bag for travel. The Synapse 25 seems to be just right but I'm worried the straps will be too painful or not right for my shape? I'm worried the 19 litre bag may be too small to fit my stuff.. Does anyone similar to my size have experience with both bags? Which would you recommend?
