I have long thought about carrying system that matched the most for my use (I have two mounted devices [total, around 3kg], which avoids the change of objectives and to quickly take a picture, and I going on a trip with the two and want to wear them all day without suffering, but around my house, sometimes I go riding in one device).
In fact, this system (such as another that I also purchased the pectoral satchel Clik Elite) is not perfect: the cameras, even if they are well maintained and do not move because they "lock" even if you do not feel their weight and the port is well facilitated suddenly exposed to dust, weather, etc. ; I am also afraid to hit them when I find myself hiking in places where I have to climb the most difficult passages ... *
... Which is not the case with the bag pectoral Clik Elite ... but unfortunately it does not exist in Clik Elite bag to carry two cameras!
I bought the two systems (the price can afford it); I will take one or the other depending on the circumstances.
* Other positives: you can wear it under a backpack without problems; access to belt lateral pockets is not hindered! In bad weather, I bought simple rainproof protections that can be strung without being hampered by the attachment of devices to the media.
