As a 215 pound bodybuilder who has gotten tired of carrying a backpack to school like a 10 year old, I started looking around for a masculine side bag, that didn't look like a womanly purse, satchel, hipster type bag. After reading every possible review on amazon I finally decided on this one. It was exactly what I was looking for, great quality material, the strap is thick and extends far lower than I need it to. This was a big issue because a few of the bags I had  tried basically dangled a few inches below my armpit and looked ridiculous. This one is perfect. Search no longer if you're looking for a quality, masculine, non flashy, messenger bag with plenty of space.
