While these collars are very strong, safe and hard wearing - they are also lightweight due to the safety clips being designed for mountaineering. Very easy to fasten and unfasten - but stays self locked if dogs are playing and accidentally release one side - because both sides have to be pressed at the same time to unfasten.
You have the choice of your collar having a handle to help control your dog when needed - or without.
