This pack it folder held all five t-shirts plus a pair of shorts for my sojourn to DragonCon this year. I'm not a small person, so my shirts are XL to XXXL (depending on how roomy I want them to be). However, all five of my shirts folded neatly and stored nicely in this folder. I plan to use this later this month for my business trip to pack my nicer shirts in for travel.

The folding instruction card is quite helpful. My 13-year-old autistic son has been able to fold his shirts much more neatly with the card to help stop him from over-folding them (too narrow) and then the shirts are a uniform size for placing in his drawers. For business travelers, I can see this would be very nice for keeping dress shirts or blouses neatly folded while in transit.
