Guy Cotten had some kid sized stuff a few years back. Not as heavy as grownup stuff, but the right basic shapes.
IMHO It sounds like you are talking yourself into a big $$$$ purchase.... If you layer it right a 3 and 7YO will be perfectly comfortable in a trash bag as they aren't sitting on the rail for hours and are not doing anything more than pulling a line from the cockpit from time to time. Anything you buy now will end up being outgrown in 6 mo let alone last till next season. Unless the 3yo will be using the 7yo jacket in 3 yrs or they are doing an opti campaign, buying anything remotely foul weatherish will be a waste of $$$. Also, the ll bean and Eddie Bauer stuff is wayyyy more than just a rain coat and well worth a look, but to each his own....
Ha.... Actually have 2 of those on the boat in case the newbs forget that it rains a bit here sometimes. Actually had to use the full suit 1 day when the guy just brought a hoodie and sweats. Worked pretty good until about hour 3 (the last race at Dillon) when all of the seams gave up simultaneously and it actually exploded during one particularly interesting Gybe.....Coleman camping ponchos. Can be trimmed to fit and cost about $5
REI has great breathable foulies for kids under their brand name. West Marine sells the PVC stuff that isn't too bad either. I have purchased sets from both places.
Pic of the West Marine stuff getting the full Alaska test on a 5 year old. 3 years later and it is still the goto gear for real rain.
