Why ODSS Recommends It:
The Ampere is the ideal layering piece for outdoor school and active days outside — soft enough to wear indoors, but warm and durable enough for any weather. Parents love its longevity and versatility; kids love how comfy it feels from the very first wear.
Sizing tip: We often use European sizing along with US sizing to help guide you to the right fit. In many cases, if you know your child's height, this actually can help guide you better than age. We did the work for you so you do not have to convert- use this chart to find their height. Outerwear is made to layer over clothes- getting this right should be all the work you need to do. When looking at boots, use current tennis shoe sizing. Boot sizes are in T (Toddler) and Y (Youth)- not by age.
