Sturdy and warm, this canvas vest from our Nike Life collection is the right layer to throw on over a long-sleeve tee or hoodie, a flannel button-down or sweater. It's cut with plenty of room and filled with low-loft insulation to avoid that overstuffed life jacket feel. Soft ribbing at the collar keeps it comfy on the neck and deep pockets keep your hands warm and your valuables secure. Try it on and you'll see: it's as simple as it is essential.
