Better in pretty much every way than the standard Errant Pack chest strap. I lost half of the original strap as it detached at some point and fell off. This cannot happen with this strap, it's very secure. The buckle itself is easier to operate and provides a better connection and the strap has a greater range of adjustment. I also think it looks nicer as well.

This is definitely the best add on for your Errant Pro. The chest strap it comes with more than suffices but this makes one handed connection so much easier. Which when travelling via plane and through airports often can be a major differentiator in your experience. Do yourself a favor and get one of these when they are in stock.

The magnetic chest clip of the Premium Chest Strap is much more robust than the chest strap that comes with the Errant pack. That said, the standard chest strap would have been sufficient.

awesome love it
