My daughter is on her 3rd year with this coat, and we could probably stretch it to 4. Absolutely no sign of wear.We bought her a 5T when she was 4, and had to roll the sleeves a bit. She's now 5 years old and wearing size 6s. Jacket still fits great.We'd tried a competitor brand originally, but it just didn't fit right, and seemed to be constantly leaking down. There was a little bit of leakage originally, but not enough to notice or affect the jacket.Good for weather 35-70, with either long sleeve or short sleeve under it. Of course, light and packable like you'd expect from down.Considering how versatile this is, easily worth the price.
