I haven't gotten to take it out yet but trust me its been packed a few times.
with the assistance of packing cubes(not TB, already had some)
2 pr of jeans
1 pr of khakis
4 t shirts
2 dress shirts
1 nylon running shorts
1 pr thin sweat pants
10.5 EEEE running shoes(Yes they fit easily in the end pockets oddly with a bit of room to spare)
1 wind breaker
some socks and undies
small amount of toiletries(I just don't take that much, but there is room for more)
a laundry kit
and to top it off a well folded suit jacket. (odd thing folding a suit jacket but if done right it turns out ok after hanging in the bathroom during a hot shower.) also proof of need for TB garment sleeve
There was room for a few small item to be stuffed here and there. but that is awesome.
