When our kids are ready to ride, we slip them into Burton's Skylar Bib Pant to keep them warm and dry as they pillage the powder. These bibs feature a light layer of synthetic insulation to take the edge off cold temperatures, while a 2-layer construction provides waterproof and breathable protection against falling snow and spring thaw. We also like Burton's Room-to-Grow system, which lets us extend the length for our fast-growing kids.
