Helly Hansen made the Girls' Jr Seven J Jacket out of the same waterproof, breathable material as Helly's adult ski jackets, so you know it can hold up spring showers as well as winter dumps. Fully taped seams amplify this jacket's waterproofing by preventing a single raindrop or snowflake from seeping through. The mesh lining makes this jacket more comfortable for summer weather, but she can certainly find year-round protection out of this jacket.
