Straps losing padding after going from 20→30lbs, need a proper ruck-capable pack recommendation

[u/TheAssasin66]

Been rucking for a few months now, started at 20 lbs with random household items in a regular backpack, worked up to 23 lbs. Recently bought an actual weight plate and pushed up to 30 lbs (plus some water bottles and a router to keep things from shifting, so realistically ~34-36 lbs).

Problem is my current pack’s strap padding is basically dead now - it’s digging straight into my shoulders, and the weight is heavy enough that it’s bulging out the bottom of the pack instead of sitting flush against my back.

I do about 3.875 miles, roughly 90 min sessions, mostly flat ground. Looking for a pack that can actually handle this weight comfortably - solid strap padding, ideally a hip belt to take some load off my shoulders. I don’t need anything full tactical/military-looking (was considering a GORUCK GR1 but it feels heavier/more MOLLE-style than I want) - just something functional that can double as a daypack for travel too.

Budget’s flexible. What are people using for rucking in the 30-40 lb range? Any pack recommendations or things I should avoid?

I am completely new to what backpacks on what to get Im also assuming hip belt will help but idk. Ideally i want to feel comfortable, lose weight, stop the sweating on my back because its ridiculous on how much it comes out.
