Keeping young hands warm, dry, and happy. The Tracker Mitt does one thing well. It keeps young hands warm, dry, and happy. Some might consider that three things, but the point is that a waterproof-breathable shell complemented by a well-insulated build ensures kids are stoked. Reinforced palms mitigate wear and tear, and a full-length gauntlet fits over jacket cuffs for a clean seal from snow and cold. It's a grom-approved upgrade.
