I'll preface this by mentioning that I'm a big guy... 46" waist, 3XL shirts, so this list may not "seem" like much to some of you!

Main compartment:
3 pairs pants, 6 tees, 4 pairs underwear, 4 pairs socks, 2 baseball caps.
End pockets:
One end took my toiletries bag... And I mean the whole, un-watered down, fully packed bag! I put my Kindle in the other end, and that was it.

I actually had more room to stuff, but this bag took what was effectively 4 days worth of clothing (none of it lightweight travel stuff either) plus personals, and made it easy to transport. I'm looking forward to many more years of lugging this thing about!
