Canon 200EG Photo Backpack

<p>I have this bag, and I love it, but I have read where the zippers can become loose, allowing the contents to fall out, especially when carrying heavy items. I carry 2 bodies, 70-200mm, 28-70mm, teleconverter, 50mm prime, along with several accessories, which can all get very heavy.</p>

<p>I have read where some people have attached straps around the body of the bag to secure it better, but I am still unclear as to how this is done. Can anyone offer advice or better yet, pictures on how to do this?</p>

<p>Thanks.</p>
