Learn how a kids ski jacket should fit, how much room to leave for layering, and when to size up in the FLOWLINE SKI JKT KIDS.
Quick answer
Choose the size that matches your child's current measurements and leaves just enough room for a midlayer—roughly a thin fleece or sweater—without gaping at the hem or restricting movement. If your child is between sizes or still growing quickly, size up only when the smaller size cannot comfortably fit that midlayer.
Why the right fit matters more than the size label
A kids ski jacket that is too tight compresses the layers underneath and reduces warmth, while an oversized jacket lets snow in at the cuffs and hem and can feel bulky on the slopes. The goal is a close but comfortable fit that still allows a midlayer and full arm movement.
Because children grow at different rates, use body measurements rather than age or clothing size alone. Measure over the base layer and midlayer you plan to use, then compare with the jacket's size options.
How much room to leave for layering
You want enough space for a thin fleece or sweater without the jacket pulling across the shoulders or back. Check that your child can raise their arms overhead and bring them forward without the hem riding up or the cuffs sliding down.
The FLOWLINE SKI JKT KIDS has elasticated cuffs and a snow skirt to help seal out snow. Those features work best when the jacket is not so loose that the cuffs hang past the wrists or the hem drops below the hips.
When to size up—and when not to
Sizing up makes sense if your child is between sizes and the smaller size cannot fit a midlayer comfortably. It can also help if your child grows quickly and you want the jacket to last more than one season.
Do not size up just to extend wear if the result is a jacket that swallows your child. A jacket that is too large can reduce dexterity, let cold air circulate, and make the hood and cuffs less effective.
Decision rules for choosing the size
- Measure over the midlayer: Take chest, waist, and sleeve measurements while your child wears the base layer and midlayer they will use on the slopes. Compare those measurements with the size options, not with their everyday clothing size. Re-measure if you change midlayer thickness.
- Check arm movement: Have your child raise both arms overhead and reach forward. The jacket should not pull tightly across the back or shoulders, and the cuffs should stay near the wrists.
- Test the hem and snow skirt: The hem should cover the top of the ski pants without hanging past the hips. The snow skirt should sit snugly without riding up when your child bends or sits.
- Decide between sizes: If your child is between sizes, choose the smaller size when it fits comfortably over a thin midlayer. Choose the larger size only if the smaller size cannot accommodate the midlayer or restricts movement. Do not size up more than one size for growth alone.
