Back in the day, like way, way back, (as in prehistoric times) parents would cross tundra, steppe, and plain with their young-lings strapped to their backs in carriers insulated with straw and covered with animal hides.

Those parents and infants alike would have had it much easier if they'd had The North Face NSE Infant Fleece Infant Bootie with their easy-entry, itch-free liner, and 100g Heatseeker insulation.
Something still missing. This is not my best jackets & coats.
