Waterproof and stylish, so far this is a nice ski jacket for my toddler. Fairly lightweight nylon. 2T has plenty of room for baselayer, sweater (if needed), and fleece for my 2 1/2 year old son. Seems like good quality material - but we've only had it for 2 1/2 weeks so it has yet to withstand the test of time. I got the blue/green combo (Rad Green) and I really like the vibrant colors - he's easy to spot out in the snow. I like that the jacket has a hood - although we haven't used it much b/c he wears a helmet when skiing.
