HR Clothing Premium Textured Knit Full-Zip Cardigan – Fawn

This is stronger for Shopify because it includes high-search keywords: Premium, Textured Knit, Full-Zip, Cardigan, Off White.

Alternative shorter option:

HR Clothing Men's Premium Textured Zip-Up Knit Sweater – Fawn

My recommendation is the first title. It sounds more premium and professional.
