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.
