I have one, and so far so good with it. Haven’t been in a downpour with it, but there’s been moderate rain and it’s held up really well as far as beading off the water with no leaking. Great for wind resistance too.
I would add a small tether to the side zipper, as it’s a very small zipper pull, and I’d also add a tethered loop to the inside to hang up when not in use.
