Find Your Size
European sizes are based on your child’s height in centimeters. Because kids of the same age can be different sizes, height is the best guide for fit.
Enter your child’s height in inches, and we’ll show the closest CM size range. This correlates to the first number in the size option. ie: 98 or 122. If CM sizing is not provided, simply choose the age provided.
💡 Tip: These are general guidelines. Always check specific brand size charts when possible, as sizing can vary between manufacturers.
Product Description
Winter adventures can take kids from snowy trails and sledding hills to ski days, outdoor school, and afternoons spent building something ambitious in the snow. The Reima Kaaranka ReimaTec Kids' Ski Jacket brings waterproof protection, warm insulation, and practical snowsport details together in a versatile winter layer made for kids who keep moving outside.
Made with waterproof and windproof ReimaTec material, the Kaaranka has fully taped seams and a water column over 10,000 mm to help keep kids dry through wet snow and winter weather. The fabric is breathable at over 7,000 g/m²/24h, helping manage moisture during active play and snowsports, while 140g Fellex® Eco insulation provides warmth for cold days. Reima gives the jacket a temperature guideline of approximately 35°F to -5°F (0°C to -20°C).
A straight cut and smooth polyester lining make the Kaaranka easy to pair with warm mid-layers, while adjustable cuffs, hem, and snow lock help kids fine-tune the fit and coverage. The detachable, adjustable hood is ski helmet-compatible, and dedicated zip pockets—including a ski pass pocket on the sleeve—keep everyday essentials close at hand. It is technical enough for days on the slopes while remaining practical for the many other ways kids spend winter outside.
Why Parents Love It
- Ready for wet winter adventures: Waterproof ReimaTec material, fully taped seams, and a water column over 10,000 mm provide dependable coverage for snow and wet winter weather.
- Warm for cold-weather days: 140g Fellex® Eco insulation provides warmth for skiing, snow play, outdoor school, and everyday winter exploring.
- Breathable for active kids: Breathability over 7,000 g/m²/24h helps manage moisture as kids ski, climb, hike, and play.
- Adjusts for the adventure: An adjustable hood, cuffs, hem, and snow lock help customize coverage for changing winter activities and conditions.
- Made for the slopes and beyond: A helmet-compatible hood, ski pass pocket, zip pockets, and snow lock add practical snowsport features without limiting the jacket to ski days.
Built for Real Outdoor Use
The Kaaranka is designed for winter days when kids are doing more than standing around in the cold. Waterproof, windproof, and breathable construction provides weather protection for active outdoor play, while the durable shell is made to handle everyday use. A smooth lining makes layering straightforward, giving families room to adjust what goes underneath as the weather and activity level change.
On ski days, the adjustable snow lock helps keep snow from finding its way inside, the sleeve pocket keeps a ski pass handy, and the hood is designed to fit over a ski helmet. Away from the slopes, its straight cut and adjustable details make it a practical winter jacket for outdoor school, snowy playgrounds, neighborhood exploring, and all the everyday adventures that happen between bigger winter outings.

We love winter gear that can move easily between the big adventures and everyday outdoor life. The Kaaranka brings together waterproof protection, warm insulation, breathability, and useful ski features without making it a jacket that only belongs on the slopes. With plenty of adjustability for fit and coverage, it is ready for ski days, snowy trails, outdoor school, playground adventures, and those winter afternoons when heading inside can wait a little longer.
