Kombi and Altitude Sports’ youth MERINO BOTTOM Pant is performing light-weight base layer great for active cool days, part of a family winter base-layer collaboration from two Canadian brands. The pant is 100% merino wool, meaning a soft next-to-skin feel, warmth retention, natural stretch and antimicrobial properties that wick moisture away and keep your child dry and warm. A stretch waistband furthers the comfort level and the fit. Anti-friction flatlock seams mean fewer abrasion points. Bright orange contrast stitching and a distinct-yet-subtle tag at the waist mark it as a premium collaboration piece. The elite heat rating is one of the warmest in Kombi’s lineup.

Collaboration Story: Kombi

New for the season, we've partnered with Canadian brand Kombi to design an exclusive collaboration of merino wool base layers. We chose a matching family kit, creating classic yet versatile styles with unique highlights in orange along the seams and zippers. Each garment of non-mulesing merino wool offers the warmth, softness, and moisture-wicking comfort ideal for a family lifestyle of winter activities in Canada’s outdoors.
