Simply put, the Volt pants are built to last. With double-layer reinforced hems, inseams and scuff guards these pants can take a beating on the slopes or while rough housing in the backyard. All this comes with the same comfort and warmth you'd come to expect from Obermeyer. As an added bonus, the Volt has Obermeyer's patented I-Grow extended wear system where you can extend the pant length by 2" for when the child grows! Shocking!
