>>790274Maybe you should look into a small hydration pack like this. Plenty of water, and just enough storage space for a headlamp/flashlight, snacks, USB powerbank, etc. No good for overnighting obviously, but ideal for day-hiking. And since it's small you won't be tempted to overload it with bullshit. Just the basics.
Doesn't have to be this exact pack, plenty of other makes and models from other companies. I just trust their reservoirs more than other brands.
