Description
Bright and bold, to melt the cold. The River runs the same 10K/10K BG ULTRACORE shell and 160g insulation as the rest of the Kids Series, critically seam sealed against a day of sitting in the snow. The hood detaches, fleece lines the collar and centre back, and the grow cuff releases an extra inch and a half of sleeve when the growth spurt arrives mid-season.

About the brand
Boulder Gear is a family-owned brand built on a simple conviction: the outdoors should be accessible and affordable for everyone, whatever their background or experience. That shows up as full-family snow kit — jackets, bibs, pants, layers and accessories across men's, women's, youth and kids sizing — made to hold up on the hill without stretching the budget. Their BG CORE™ and BG ULTRACORE™ waterproof/breathable shells handle real winter weather, Repreve® recycled insulation adds warmth, and kid-specific touches like grow cuffs and reinforced knees help stretch one season into two. At Mountain Sports, we love Boulder Gear because it gets whole families outside in genuinely capable gear — the brand you can outfit three kids in and still make first chair.
