Can these be worn as regular pants when not swimming?

Yes. The fabric and cut work as everyday khakis for office or casual wear. The quick-dry material and built-in liner do not affect the appearance or comfort when worn as standard pants.

How do I choose the right size?

Measure your waist where you normally wear pants and select the corresponding waist size. Then measure your inseam from crotch to ankle and choose the closest inseam length. The slim fit runs narrow through the leg.

Does the liner replace underwear completely?

The built-in liner is designed to be worn without separate underwear. It is secured at multiple points to prevent shifting and provides coverage similar to compression shorts.

Why it's on GiftsFeed

Stretch Khakis with Built-In Liner Short

Most khakis turn dark and saggy when wet, and swim trunks look out of place anywhere but the beach. These solve the problem by building both functions into one pair of pants. The four-way stretch and quick-dry fabric mean you can move between environments without planning an outfit change, and the liner stays put without bunching. For anyone who hates carrying extra clothes or wants to simplify their wardrobe, this is the rare hybrid that actually works in both contexts instead of compromising on each.

Good gift when

People who want one pair of pants for land and water
Travelers looking to pack lighter without sacrificing options
Anyone who values quick-drying fabric over traditional cotton

Skip it if Slim fit runs narrow through the thigh and calf, so those preferring a relaxed or straight cut should look elsewhere. The liner is permanently attached, which some find restrictive compared to traditional underwear options.

The details

These khakis double as swim trunks. The Quicksand Khaki colorway delivers a classic tan shade in a slim-fit silhouette, complete with a built-in liner short that eliminates the need for separate underwear. The fabric stretches in four directions and dries quickly, so you can wear them to the office, jump in the pool at lunch, and head back to meetings without changing.

The construction includes reinforced belt loops, a zippered back pocket for valuables, and a waistband designed to sit comfortably without bunching. The liner is secured at multiple points to prevent shifting during movement. These are cut in a slim profile through the leg with a slight taper from knee to hem.

Available in waist sizes from 28 to 40 inches and inseam lengths from 28 to 36 inches, the fit accommodates a range of builds. The fabric blend provides structure without stiffness, and the stretch recovers after washing. Pair them with a button-down for work or a t-shirt for weekends. When they get wet, they shed water quickly and dry faster than cotton chinos.
