Sports: Clean Spec & Fit Attributes

Extract and normalize the attributes a sports buyer filters and compares on from {specifications} for {product_name}. Prioritize the decision-critical ones: size and fit, material, weight, skill level, intended use case, age range, and any safety or certification detail. Present each as a clean, consistent attribute-and-value pair a shopper can scan and compare across products — normalize units and phrasing so values line up. Only record what {specifications} or {description} actually states; never guess a size, weight, or safety rating. Where a value is a range or has an important condition, keep it precise rather than rounding away the nuance a serious buyer needs.
