Filled with synthetic down insulation, the Storm Jacket will help your kid will stay toasty warm. It's toasty and still low-bulk enough that you can layer it under a tougher waterproof shell for use on the slopes. The hood is completely removable and the jacket is reversible so you can mix and match for different outfits.
