Levi's 511 Slim Fit Flex Men's Jeans vs Levi's 511 Slim Fit Jean

Both are the Levi's 511 Slim Fit, so the cut is the same: slim through the thigh, slightly tapered to the ankle, sitting below the waist. The real difference is the fabric and the wash. The Flex pair uses stretch denim for more give from day one, while the standard 511 is a 99% cotton, 1% elastane jean in a darker rinsed wash that dresses up more easily. Owners of the 511 line praise the versatile fit and consistent sizing; the common complaint is that the slim leg feels tight through the seat for larger builds.

• Choose the 511 Slim Fit Levi's Flex if you want more stretch and give in the denim for all-day comfort and a casual everyday look.
• Choose the Levi's Men's 511 Slim Fit Jean if you want the classic 511 in a darker rinse that works for both casual and slightly dressier outfits.
