Men’s swimsuits fall into seven main categories — swim trunks, board shorts, swim briefs, square-cut shorts, jammers, hybrid shorts, and bermuda-length shorts — with the 2026 US trend favoring a 5–7 inch inseam and tailored fit.

The right swimsuit changes everything. A suit that fits your activity and style makes the beach, pool, or lap lane more comfortable, and the current shift toward shorter, cleaner silhouettes means even casual choices need a second look. Here is exactly what the seven types deliver, which one you actually need, and the 2026 trends worth knowing.
Swim Trunks: The Versatile Standard
Swim trunks are the most common men’s swimsuit in North America, and for good reason. They typically land at a 5–6 inch inseam — mid-thigh — with a loose-to-relaxed fit, an elastic waistband, and a built-in mesh lining. Made from quick-dry nylon or polyester, they work for casual pool time, beach lounging, and light water activities. In 2026, the best trunks have a tailored cut and softer linings, moving away from the baggy 2010s look. Most men who want one suit that does everything reach for this style first.
Board Shorts: Built for Surfing and Active Water Sports
Board shorts are the longest of the common styles, with an 18–22 inch inseam that reaches the knee. They have a non-elastic waist secured by a drawstring, and the cut is loose enough that a surfboard leash fits underneath. Originally designed for surfers, they remain the go-to choice for anyone in the water for extended active sessions — surfing, wakeboarding, or kayaking. Board shorts usually lack a built-in mesh lining; the surf culture prefers wearing them without extra layers. If your priority is range of motion in the water and sun protection for the legs, board shorts win.
Swim Briefs and Jammers: For Performance Swimming
Swim briefs — often called Speedos — are the shortest cut, with a 2–4 inch inseam, a V-shaped front, and a tight body-hugging fit. They are standard in competitive swimming because they create minimal drag and allow full leg mobility. Athletes training for speed or flexibility choose briefs. Jammers serve the same purpose but extend to the knee at 16–18 inches, fitting like a bike short without padding. The skintight, chlorine-resistant polyester reduces drag while covering more skin. Lap swimmers and triathletes prefer jammers for the balance of coverage and performance. Neither style is meant for lounging; both are purpose-built for the pool.
Square-Cut Shorts and Hybrid Shorts: The Middle Ground
Square-cut shorts sit at the upper thigh with a 4–5 inch inseam and a boxy leg opening. They offer more coverage than briefs but a tighter cut than trunks, making them a stylish choice for fitness swimming and modern beach style. On the other side of the spectrum, hybrid swim shorts look like everyday casual shorts — a 7–9 inch inseam, belt loops, pockets with drainage — and function as swimwear. Made from recycled polyester or organic cotton blends, they are the top pick for the beach-to-bar traveler who wants one piece of clothing for the whole day. The hybrid category is surging in 2026 because of its versatility.

Avoid These Common Mistakes
Even the right type can go wrong with the wrong fabric or fit. Baggy board shorts worn in the pool look dated and feel heavy in the water — the modern alternative is a tailored 5–7 inch trunk. Wearing mesh-lined trunks for lap swimming adds drag and slows you down; choose jammers or briefs instead. If you swim in a chlorinated pool regularly, make sure the suit is labeled chlorine-resistant, or the fabric will degrade within weeks. For long sun exposure, look for built-in UPF protection or layer a rash guard on top.
| Type | Inseam | Best For |
|---|---|---|
| Swim Trunks | 5–6 inches | Casual pool, beach, everyday wear |
| Board Shorts | 18–22 inches | Surfing, active water sports |
| Swim Briefs | 2–4 inches | Competitive swimming, tanning |
| Square-Cut | 4–5 inches | Fitness swimming, modern style |
| Jammers | 16–18 inches | Lap swimming, triathlon |
| Hybrid Shorts | 7–9 inches | Travel, beach-to-bar versatility |
| Bermuda/Knee | ~18 inches | Taller or plus-sized builds, volleyball |
2026 Trends: What Has Changed
The biggest shift in men’s swimwear is the inseam. The 5–7 inch length has fully taken over in the US — anything longer now reads as a deliberate retro choice. Tailored cuts and slimmer silhouettes have replaced oversized fits across most brands. Patterns are more restrained than they were five years ago, with minimalist solids like navy, black, and earthy tones dominating. Sustainable materials — recycled polyester and organic cotton blends — are now a top consideration for buyers. A retro revival of high-waisted cuts and color-blocking from the 1970s and 1980s adds a current option for style-oriented shoppers. These trends mean the same styles you already know now come in better fabrics and sharper proportions.
The single best principle for choosing: match the suit to the activity. Occasional beachgoers should prioritize comfort with a mid-length trunk. Weekly swimmers need support, which means square-cuts or jammers. Competitive athletes require the drag reduction of jammers or briefs. When in doubt, go with a 5-inch inseam trunk in a solid color — it is the most versatile starting point in the 2026 market.
FAQs
What is the most popular type of men’s swimsuit in the US?
Swim trunks with a 5–6 inch inseam are the dominant style in North America. They balance coverage, comfort, and style better than any other single type, which is why most casual beach and pool visitors reach for them by default.
Can you wear swim briefs to a public pool?
Yes, especially when you are swimming laps. Swim briefs are standard gear for competitive training in pools and are widely accepted. Some men choose them for tanning at the beach, though personal comfort with the minimal coverage matters most.
What is better for lap swimming: jammers or square-cuts?
Competitive swimmers typically prefer jammers for training, but square-cuts remain a solid option for moderate lap swimming.
