Replying to Backpack capacity

Looking for a backpack to haul my gear around this season. Not to serious mostly inbounds forrest stuff, maybe a little cat skiing. Debating between a 11L and 16L back pack. I will be carrying gopro and pole, snacks, extra layers, and extra gloves. Which would you pick between these two for the amount of things it can cary and how much it sticks out(lifts).

(Sorry if this thread was already made. I checked and couldn't find anything.)
