best cycle backpack up to 40 pounds?

[Torvi]

ive been looking for something that i could put my pump few tubes and some food into, not too big not too small maybe additional bottle of water too.

What i want to handle in a backpack:
pump:

bottle: high5 750ml bottle
others: dents, few tools, phone, few energy bars/gels.


So far i have my eye on those:

its small and will be just for all i had in mind but im afraid that it can pretty much tire my left shoulder and be tight fit inside.

bigger option and i really like how it allows airflow as my back gets sweaty really fast.

this also looks nice but im not sure if it will handle my pump and others

this was actually a first pick but then i started to look around after something "better"

Point to note, im not looking for anything "fancy" i just want a backpack that will get all the stuff inside and dont cover my back too much.

Look at Mountain Warehouse & Trespass too. A variety of options and generally not expensive.

I have been using a £9.99 one from Lidl for the last two years on my commute and shopping trips, as well as some weekend rides.. It came complete with a multi-tool, a puncture repair kit and some tyre levers. It now looks utterly filthy, but hey, it works. It takes a 17" laptop too, wrapped in a bin liner. I cut off the padded waist strap a week after I bought it. It was way too high, and I'm not tall either. An absolute bargain....but cool it ain't.

Edit: It can, at a pinch, carry ten 500mL cans of beer.

There's loads of similar threads on the subject, but HERE'S one that springs to mind.

Not sure it'll help but you never know.

40lbs is too heavy for any distance. Best to carry in panniers.
