From autumn hikes to winter afternoons at the sledding hill, keep your kiddo warm in the Patagonia Boys' Radiant Flux Jacket. Made from a stretch fleece fabric, this jacket handles changing conditions with ease thanks to a grid back which enhances breathability and reduces bulk. A high collar offers extra protection from the cold, while raglan sleeves ensure chafe-free comfort when he's wearing a pack. The jacket's regular fit layers over a long-sleeve tee on cool hikes and easily fits under a shell for midlayer warmth when conditions demand waterproof protection.
