What happens when you take all the features of our Summit jersey and make it in Junior sizes? The next generation of shredders benefit from the same performance you expect from us, ensuring that they'll be comfortable and have a great experience on the bike. The Junior Summit Jersey is constructed from lightweight, breathable, and fast-drying Transfer fabric. Like the rest of the Summit jersey line, this piece is made from recycled polyester, because we're thinking about the future while designing for the future of mountain biking.
