Good times await for your grom when you bring them home the Vernon Insulated Jacket. We put in 100gm Polyfill Insulation into a V-Science 2-Layer Shell Jacket. It comes with a 10,000mm / 10,000gm2 waterproof/breathable rating and Critically Taped Seams to help keep them dry. You surely strap a helmet to their melon so we threw in a Helmet Compatible Hood. And we know they grow up fast, so we thought up Grow-Tech which helps the jacket grow with them. A go-to jacket this season and the next.
