New parents are so anxious to keep their babies warm they sometimes overdo it; keep your little one's core warm without overheating with the Patagonia Infant Boys' Retro-X Fleece Vest. Thick, warm fleece keeps the heat his little furnace generates near his body, while a windproof lining prevents wind from robbing your son of soothing warmth. A vest means no sleeves, which means significantly less crying and fewer flailing limbs when you're getting your boy dressed to go outside. Plus, a tapered collar lets you zip him up without worrying about rubbing his little chin raw. Your little one will appreciate the targeted warmth and extra mobility of the vest design, while friends and family will go nuts over the mini-mountain-man look.
