Been a Lens Coat user for many many years but have noticed that the quality seems to have dropped over the last few times I have purchased them. I have tried some alternatives not mentioned here but never got on with them. As my Lens Coat for the 600 pf was becoming very tatty and frayed at the edges I’ve looked at both Chasing Birds and Rolan Pro and eventually decided on the Rolan Pro as a replacement. So far well impressed very snug fit, tailored edges and easy accessible buttons etc. Time will tell but the quality seems excellent and definitely an upgrade on Lens Coat IMO.
