To keep our grom-in-training snug on wintry treks, we zip them into Patagonia's Reversible Down Sweater Hoodie, knowing the ultralight fill will keep both their cozy and their stoke fueled. The elastic-bound cuffs stay out of their way as they carefully secure their boots' hook-and-loop straps, while the raglan sleeves give them full movement freedom to explore snowy trails.
