Why outerwear-first narrowing works better here
Jackets sit in a different part of the browsing journey than lighter tops. People often care about shape, coverage, materials, structure, and seasonal use, which makes a focused category more useful than a broad sheet full of mixed apparel entries.
That is why a jacket-first page adds real value. It turns a vague clothing search into an outerwear lane that is easier to compare and easier to summarize for shoppers.
