Actually, they do. You can move around the Aircraft in icy ramp conditions like you would under normal conditions without the distraction of falling on ice, so you get done with your Walk Around way quicker and that reduces your exposure time: therefore you don't need as much bulky clothing. You still need a good lightweight face mask and good gloves & hat that covers your ears. All those items can be very easy to carry in a backpack along with your Nano Spikes. YMMV.
