The Ultimate Photographers bag, Prime, and MKII, plus the Default bag all have some new upgrades. We have been working on a detachable waist strap for a while now--and we are very happy to be able to include it with the bags at no extra charge! When riding, we find that a sternum strap and cinching down the shoulder straps provides plenty of stability. If you find yourself hiking around with a loaded bag, having a waist strap is really beneficial. Fortunately it is easy to install/remove this waist strap--it is secured with a 2" tensionlock (double it back as pictured for no slipping!) and kept in place with a ring snap. The sternum strap is now a smaller and less intrusive, but just as effective.
This is how all bags are being shipped now.
