There is no way more than 1 day worth of clothes fit in a backpack, and this does not include accessories. Am I just supposed to buy clothes at the destination country?

How many and what kind of clothes did you carry and what was your folding method (if you can explain)? I can't believe "weeks worth".
Can take even less if you do laundry once at the half way point.
It also depends on where we are going. If I am going to the Middle East, I will not need much besides two robes. :D
Alaska? Yeah, gotta pack up.
My folding method was: get some cheap packing cubes, one large with shirts (just flat), one smaller with underwear and socks (just put there) and one with toiletries, nothing special at all. You can stuff lot more than you think into 40 liters. Jeans and sometimes jacket I just stuffed there.
btw I was able to sneak that backpack to ryanair flight even :-D
You can wear shorts/jeans multiple days, so just need multiple underwear and socks. Pack some light t-shirts and shirts rolled up.
Merino wool t-shirts and some other natural materials can be worn multiple days.
Also depends on weather, if it's winter and not sweating and humid you could wear the same top multiple days too.
Base layer (thin material), mid (fleece) and waterproof/windproof shell (light).
