>>2040419just go in amy outdoor or sports store and try packs. I have nought few packs in decathlon they are great anf you get garantion for 10 years or somthing like that. i have their trek 900 70l + 10l backpack and it is awsome, it has suspension breatheble back, ito doesnt have mesh pocket but it has stuff for gambits or swhatever . 2 deep side pokets for 1-1.5 l bottles and you can take botles without taking off backpack.
it has hip pockets, and so on....
you can carry lot of weight and when you put it on back it doesnt seams heavy at all.
all it needs is mesh pocket. you can open it like suit case and. it is best backpack i have ever used..
You have smaller sice i think 60+10...
but i would go for 70l again you can use straps inside of it and outside it to make it smaller if you dont need all 70l. Also i have 40l backpack but when ever i go camping i use 70l pic related. It truly my favourite stuff i can bring whatever i need, it is comfy and practical and so on. best back pack ever
