I've actually been using this bag for a week or two and it fits (but just barely).

The bag is a complete piece of junk though so looking for something more high quality.
I'm usually carrying 4 pairs of underwear; 4 undershirts; 6 pairs of socks, sneakers, PJs, a spare pair of dockers, a pair of jeans, few casual t-shirts, and a medium sized toiletry bag.
