Boasting bright colors and innovative technology, the Obermeyer Sierra Toddler Girls Ski Jacket will keep her warm all winter long. HydroBlock Sport 10K/10K waterproof/breathable technology keeps moisture out while hydrophobic 220 gram insulation traps heat in. The 'I-Grow' Extended Wear System allows the sleeve length to be increased by 1.5 inches so she can get a few extra years out of her Sierra jacket. Other great features include reflective trims, integrated clips to retain mittens and gloves, an integrated adjustable powder skirt, and a working compass with secret pocket.
