More recent lenses have nano coated front elements, and in the last couple years, nano coated filters are abundant. Nano coatings make water bead and run off much better than conventional multi coatings. Plus, a quick wipe from a dry(ish) microfiber cloth kept in a zip lock bag in your picket leaves a clean and streak free glass finish (conventional mult coatings leave a smeared/ streaky finish) to try and get the next shot.

I bought a nano-coated filter for my Canon 24mm TSE II on the basis that it's almost impossible to keep such a large front element droplet free in a heavy mist (aka fret), while adjusting the movements.  Amazingly it works well enough to be worth the money.
