The JANUS pocket is great for a Gearslinger bag. It integrates perfectly into the existing strap and easy to access.
There's velcro running the entire length of the channel the removeable strap passes through. This is good for keeping the strap in place, so the pocket can't slide up/down. This is bad, if you make the mistake of removing the strap and need to put it back. It's hard to reinstall due to the velcro.
Overall, I LOVE the item and would highly recommmend it.
Pros: Great design, extremely rugged, looks great
Cons: removing/reinstalling the strap is tough
