A great rainsuit for Northern Minnesota!  We used them at the end of the year for snow as well and just had the kids put their snow clothes on underneath.  I am a bit disappointed in the waterproof feature as all 3 of my kids seem to still get wet, but the mud is the main reason that these have been a lifesaver!  No more head to toe mud all over 3 kids when they come in from playing after it rains!  I followed other reviewers recommendations and ordered big with the ability to cinch the waists- worked great!  The neoprene ankles and wrists are a big hit with the kids because it really does a good job keeping the wet out- they like them better than their snow bibs because it keeps the snow out of their boots! Definitely a hit!
