10K Waterproof Shell
160g Mapped Insulation
Stay-in-Place Snow Skirt
Description

Big-mountain performance, toddler-sized. The Khai pairs a 10K/10K BG ULTRACORE shell with 160g of insulation through the body and sleeves, critically seam sealed so the weather stays outside. A stay-in-place snow skirt and a detachable hood handle the deep days, fleece lines the collar and centre back where it meets bare skin, and the grow cuff lets the sleeves out an inch and a half when this season turns into next one.

First Chairs
Seam sealed and insulated for full days out.

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.
