Kids' gilets

it warms the torso but leaves the arms free for climbing and playing, so they keep it on longer than a jacket. In spring and autumn it is often enough on its own, in winter it serves as a mid-layer under a jacket without bulk in the sleeves. An insulated one keeps out the cold, a softshell one mainly the wind. Check the length at the back so it covers the lower back when bending forward — children are bending constantly. And count on reflective elements, a gilet is usually the outer layer precisely at dusk.
