This neoprene strap has several advantages: - You are no longer a billboard for your brand - you attract less attention (which can be a plus in some cases) - It acts as a shock absorber when your walk: it your neck that are more tired playing this role and he will thank you at the end of the day. - It has a non-slip face which secures your device when the doors to the shoulder (but beware of pickpockets) - Quick couplers allow you to change straps quickly.
In short: since I tried it, I would not change it for anything in the world! (I wear a semi-pro body with grip and zoom - 3 kg of equipment on the shoulder or slung traveling - for 8 hours a day over a week without tiring)
