I have a thing for T Shirts, I think I own around 70 ish, so when I travel clearly I pack a fair few T's. I kinda knew that rolling them was the best way to pack em but this didn't prevent them from coming out creased and unrolled at my destination. I mean think about how often your bag gets tossed around at airports when not in your possession. This however looks like a pretty cool way to keep them rolled and tight. Hey if it works for the army it most likely works right?
