I have been using the Lencoat protection for several years on all my long focal lengths and have never had any problems, not even with lens fogging.
I also have the lens coat rain protection, very convenient and practical.
Sure, LensCoat's products aren't cheap, but neither are our precious lenses, so personally, I've never looked for more affordable alternatives.
I find that having a neoprene layer that protects my lenses' body is very important for several factors.
For the kind of nature photography that I practice, which is at least 50% of cases inside the woods, having protection from possible scratches caused by branches or others while walking is important. Not to mention that it is not always possible to keep my hands perfectly clean, and having additional protection that repairs the paint or plastic of my equipment makes me live more comfortable.
Some time ago I sold my 500mm to a dear friend to upgrade to the 600, and he removed the protection because he didn't like it, and under it, the lens it was practically new as if it had just left the factory.
I have come back several times with the kit completely wet, and not just the photographic equipment. However, it has never been a problem for me.
When it happens, I dry all with an old towel I keep for those occasions, I remove the Lenscoat protection and put it to dry.
Then I put the camera body without the filler cap and the lens without the caps, inside a carton box with a moisture-absorbing kit and the tablet, after a while, usually 6/8 hours, all moisture was collected.

Obviously, if I leave home knowing I will encounter bad weather, I use rain protection, but it can also happen to fall or sink into fresh snow on a bright sunny day, filling up with snow and I cannot predict that.
Another good advice that I allow myself to give is to store the lenses placed horizontally and never vertically as is often the case by leaving them inside the backpacks. If left vertically for a long time, with the change of temperature and seasons' evolution, the grease used to lubricate the focusing helicoid, deposits in the lower part anticipating the AF whistle's classic problem caused precisely by the inadequate lubrication. It is a problem that can be solved by sending the lens for assistance, but the later it shows up, the better.
). As for camo, while pictured here is my ghillie jacket, I have a 3d camo small tarp (in the car at the moment) that I plan to throw over the cam and tripod in this fashion. It's weightless and I've already carried the cam on tripod on shoulder with it and it wasn't particularly in the way, at all, and easy to get my left arm under and drom under without thought.
