Men's Long Sleeve Mock Neck vs Nike Pro Dri-FIT Fitness Mock Neck Long Sleeve Top

Buy the Nike Pro Dri-FIT if you want a slim, stretchy base layer for gym work and you know your Nike size. Buy the generic mock neck if you want a roomier regular fit, a zipper closure and two front slip pockets for everyday wear. Nike's Pro line has a long record with lifters and runners for holding shape through sweat and washes; the generic top's flat-lock seams and anti-odor finish are solid on paper but unproven. Build quality favors Nike on fabric reputation, while the generic top wins on features and fit range.

• Choose the generic mock neck if you want a regular fit, a zip neck and pockets for casual wear or layering.
• Choose the Nike Pro Dri-FIT if you want a slim, stretchy training top from a brand with a proven fitness record.
