It becomes a bulletproof vest when you pull on the tabs by the shoulders. I bought it last year because I thought it was cool, and it has been sitting in my closet untouched ever since. It's in brand new condition. Has enough room for a PDW, a laptop, etc, also has molle on the vest section for mag pouches or pistol holsters. Text 4077902797 for offers or trades. If trading, I'm only taking trades of similar value or more as my main intent is to get my cash back for this backpack. I am taking reasonable offers also. I'm interested in trading for bulk 5.56 or a combination of 5.56 and 9mm
