When the snow begins falling, slip him into the Spyder Toddler Boys' Mini Propulsion Pant and let him explore the backyard. Its Xt.L laminate provides waterproof, breathable protection, while critical seam taping keeps water from seeping into places most likely to get wet. Thinsulate insulation keeps him warm whether he's discovering new lands or learning the ropes on the bunny hill. The attached stretch fleece vest helps keep his core warm. Snow gaiters keep snow out of his boots, so he'll stay warm and dry while he plays. The Mini Propulsion includes Small to Tall cuffs which allows you to extend the length of the pant by an additional two inches when the stitch is released.
