Good for handling the tripod in cold weather (which is what I bought it for)
The best tripod is one you take with you. Buying carbon fiber went a long way to increase my usage (and resulting image quality), but... over-the-shoulder comfort wasn't there for long hikes. Tried foam bike tape, but not enough cushion. These covers are substantially thicker and more comfortable. Basically foam pipe insulation with a stretch cover. The only downsides are:
-- too long (fabric over-covers can't be trimmed)
-- added bulk makes fit in my pod's travel case very very tight.
