I received this Propper Expandable Backpack back in December and this week at the NRA 148th Annual Meetings it got a total work out. Covering the show was going to be a problem this year as my son and now grandson had all their camera and recording equipment with them. What we did and it worked out really well, was pack all our equipment in my bag to carry around during the four days we were at the show. Really, I was so happy to have this Propper bag, and the Expandable part was great! I had my computer, cameras, recorders, and all the cords, batteries, lightening, and still had room for the paperwork we received from the booths. As we were driving home, all of us mentioned how nice it was to have everything in one bag and in the many different compartments the bag offers. So, if you are looking for something for Mother’s day, Father’s day, or a Birthday, this is the bag for you. They come in several colors. Just check out their website at the listing above. In fact, check out all their products. It’s the best on the market.
