If you're in Los Angeles next week, Kata Bags is going to be at Samy's Camera September 20-22 hosting their Draw, Shoot and Win Contest. You could win a Kata 3N1-25PL bag.
I have been using a bag from this series since the first iteration, and I love it. DISCLAIMER: I did receive my first 3N1 bag to do a review of it. Since then, however, I've purchased my own upgrades.
