Absolutely love the Tuffo Muddy Buddy overalls. I cannot say enough. My son was size 24mos - 2T so I ordered the 3T knowing he would be drowning in it. But it still fit because of the elastic wrists and ankles and the material is not bulky. Sure he looks like a huge yellow M&M. (My husband calls it a hazmat suit.) It's really safe - motorists can easily spot him on the gloomiest of days. The double zips make it quick to get in and out. The seams are taped and there are short storm flaps behind the zippers. My son would not wear a snowsuit this past winter. I wasted a bit of money trying different snowsuits/snow pants but nothing doing. So I put an extra layer of fleece on him and zipped the Tuffo Muddy Buddy Overalls over, paired with snow boots, velcro-close mittens and hat. He loved the snow after that. Now that he's size 3T - 4T it still fits! We go out every day rain or shine. Even for a rainy day at the beach it was perfect! The elastic bottoms are a little tough to get over his size 9/10T rain boots but they stay put and he doesn't get any water in even with vigorous splashing. He pulls his hands into the sleeves to keep them out of the rain. He doesn't sweat/overheat in it and it doesn't leak. He's always dry when we take it off. I think the material feels funny to him because he prefers a baseball cap on his head with the hood over. Definately buying the next size when this one gets too small. Wish they had adult sizes!
