Can I wear swim trunks as regular shorts?

Yes — this is one of the biggest trends in men's swim. Many modern swim trunks are designed as hybrid "swim-to-street" shorts with quick-dry fabric, a tailored fit, zippered pockets, and a clean aesthetic that works for errands, lunch, or casual outings. Look for unlined styles with stretch fabric and side pockets for the most versatile swim-to-street option.

How do I keep swim trunks from riding up?

Riding up is usually caused by a too-loose fit or fabric that bunches when wet. To prevent it, choose swim trunks with a slight taper through the thigh and a stretch fabric that moves with you. Compression-lined trunks also help because the liner keeps everything in place underneath. A proper waistband fit (snug but not tight) prevents the whole trunk from shifting upward.

Should I buy lined or unlined swim trunks?

Lined swim trunks have a built-in mesh or compression liner that provides support and eliminates the need for underwear. They're ideal for active swimming, running, and water sports. Unlined swim trunks offer a looser, more relaxed fit and dry faster since there's no extra fabric layer. Many guys prefer unlined for casual beach days and wear them with compression shorts underneath for extra support when needed.

What inseam length should I choose for men's swim trunks?

Inseam length depends on your build and preference. Short swim trunks (5 inches or less) hit mid-thigh and suit athletic builds or guys who want a modern look. The 7-inch inseam is the most popular all-around length, sitting just above the knee. Longer swim shorts (9 inches or more) provide more coverage and are ideal for water sports, volleyball, or a more relaxed fit. If you're between 5'6" and 5'10", a 7-inch inseam is a safe starting point. Taller guys may prefer 9 inches.

What's the difference between swim trunks and board shorts?

Swim trunks typically have an elastic waistband with a drawstring, an above-the-knee length (5–7 inches), and a built-in mesh liner. They're designed primarily for swimming. Board shorts have a flat waistband with a snap or Velcro closure, a longer length (9–11 inches), and are usually unlined — originally designed for surfing. Swim trunks tend to dry faster due to lighter fabric. Many modern hybrid styles blur the line between the two.
