Long Swim Shorts Popeye: Fit, Print and Beach Use

Quick answer

The Thunderpants Long Swim Shorts Popeye are a solid choice if you want extra coverage without the bulk of a lined short. They run true to size, sit at mid-thigh, and the unlined recycled nylon fabric dries fast. They are not for you if you need built-in support or a gusset.

Who are these swim shorts for?

The Long Swim Shorts Popeye are designed for people who want a longer, more modest swim short that still feels light and unrestrictive. The mid-thigh length gives you more coverage than standard swim trunks, and the unlined construction means no twisted or bunched lining after a swim. They are especially popular with men and women who prefer a simple, functional short for swimming, paddleboarding, or lounging at the beach.

Because they have no gusset, they are best worn over a swim brief or as a standalone short if you do not need extra front support. The recycled nylon fabric is soft, durable, and dries quickly, making them practical for repeated water use.

Fit and sizing details

The Long Swim Shorts Popeye are available in sizes S through 2XL, and the fit is consistent with other Thunderpants bottoms. The waistband is elasticated with a drawstring, so you can adjust the fit. They sit at the natural waist and taper slightly at the leg opening to stay in place during activity. The mid-thigh length is intentional—it provides coverage without restricting leg movement.

If you are between sizes, sizing up gives a looser fit through the thigh. There is no built-in mesh liner, so you will want to try them on with whatever you plan to wear underneath. The fabric has a little stretch, but not enough to compensate for a too-small waist.

Popeye print and fabric choices

The Popeye print is a fun, nautical-themed design that stands out without being loud. It is printed on recycled nylon, which is lighter and softer than the polyester version Thunderpants tested earlier. The nylon version is unlined, which reduces bulk and drying time. If you prefer a lined short, note that this version does not have one—the trade-off is a simpler, more comfortable short that moves with you.

The recycled nylon is also more environmentally friendly than virgin synthetic fabrics. It holds color well and resists fading from sun and saltwater. The print is screen-printed, so it should last many washes if you rinse the shorts in fresh water after each use.

Diagnosis: Is the Long Swim Shorts Popeye right for you?

• Symptom: You want a swim short that covers more of your thigh and does not have a lining that twists or bunches. The mid-thigh length and unlined construction directly address this.
• Likely cause: Standard swim trunks often have a short inseam and a mesh lining that shifts during swimming, causing discomfort. Switching to an unlined, longer short eliminates that problem.
• Corrective action: Choose the Long Swim Shorts Popeye in your usual Thunderpants size. Wear them over a swim brief if you need front support. For most people, this short will solve the lining-twist issue and provide comfortable coverage.
• Stop or choose another option: If you need built-in support or a gusset, this short is not for you. Consider a lined swim short or wear a supportive layer underneath. The Long Swim Shorts Popeye are a simple, unlined short—great for coverage, not for support.
