Does anyone here have tips on packing a big hoodie in a flat way? I have my college hoodie (Champion, sz S) stuffed into a size 4 TSS (not overkill, believe me!) but even then, it's kind of thick. When combined with my SE and Snake Charmer in the lower pocket of my S25 and a laptop, large document DOP and textbook in the main compartment, my S25 bulges uncomfortably against my back.
I'm currently trying to rearrange my setup so that my hoodie is in the lower pocket and have the SE + SC in the main pocket, but I don't know if that'll help. I'd be very interested in hearing solutions, be it products (packing cubes??) or whatever. The aircon in my school library and lecture rooms is really cold, to the point that even long-sleeved shirts or thinner cardigans don't help me, so I do need an extra layer to stay warm.
