Today at work a coworker and myself had a little bet going about which was the best way to pack clothing. I personally have been turned on to the Pack-It system that we sell, but we were discussing which weighed more, rolling your clothes or keeping them folded flat. She was convinced that rolling your clothes made them heavier. I said that it would weigh the same because they're clothes, you aren't adding anything to them if you roll them. So we folded them flat and added them to a backpack and weighted them with the scale. It came out to 6.3 lbs. Then we rolled them and added them to the backpack and it came to 3.6 lbs. The only reason folding them weighed more was because she left them in the pack-it folder. She was dumbfounded. She couldn't believe that rolling the clothes was the same. She just couldn't wrap her head around it.
Anyways, the scale is on sale right now for $14.99 originally for $19.99.
