Old Navy Slim Built-In Flex Jeans review

Old Navy's Slim Built-In Flex Jeans are the cheapest way into a slim jean that still fits a wide range of men. Old Navy defines its slim cut as fitted through the hip, thigh and leg, and the Built-In Flex denim adds stretch so the narrower leg is easier to wear. The size range is the standout: waists from 26 to 54 and lengths from 28 to 34, plus a separate Tall fit on the same page, which no premium brand here matches. The list price is $49.99, and the Light Wash pair was $24.99 in an early Black Friday sale when we checked in November 2026. The product page shows 11,538 ratings. What you give up is detail: the fabric weight and blend were not shown in the page text we could load, and the denim will not age like the organic and selvedge options from Nudie Jeans or AG. Free shipping starts at $50 for Encore members.
