Welcoming summer is exciting, but when you pull those ratty board shorts you’ve had for-freaking-ever out of storage? It’s kind of anti-climactic. That’s why it’s a great time to buy new swim trunks for summer.

Be honest. Your go-to pair is probably at least a few years old by now. They’re a little saggy. The color is faded.

At best.

That’s why a new swimsuit is the right first step to feeling like a stylish guy on the seaside this summer (say that three times fast).

Like a lot of your summer wardrobe, it feels just plain wrong to spend a buttload of cash on swim trunks to cover your butt.

So our team rounded up our favorite affordable swim trunks for guys. This year, try a bold pattern, retro fit, or even a neon color to fully carpe that sunny diem.

Below, 15 of our favorite men’s swim trunks for summer, all under $100:

1. J.Crew, $79

SG Says: J.Crew is a great place to go for reliably preppy swim trunks with a smaller price tag. This style comes in reliable navy, green, and blue, and clocks in with a fashion-forward 6″ inseam.

They’re also almost always having a sale, so be sure to check the site for a code to enter at checkout.

If you’ve been looking to flash just a little bit more thigh, these could be the swim trunks for you.

2. Patagonia, $69

SG Says: Not looking for anything flashy with your swimwear? No problem. Patagonia’s iconic Baggies are the affordable, no-frills hybrid trunks you’ve been looking for.

Wear them to the beach. Or wear them to the bar. Dealer’s choice.

3. Fair Harbor, $72

SG Says: These patterned board shorts from Fair Harbor give classic surfer vibes in a modern way.

4. Bather, $90

SG Says: Here at SG HQ, we love an unexpected color when it comes to summer wear.

Forest green? For summer swim trunks? Groundbreaking!

And sub-$100 for Bather is a steal. Season after season, the brand continues to put out affordable, stylish swim trunks. Score!

5. Polo Ralph Lauren, $99

SG Says: These seersucker swim trunks from Polo Ralph Lauren look immediately lived-in…in a good way.

The fabric gives off a laid-back vibe, which matches nicely with a relaxed beach or pool day and no other plans in sight.

6. Marine Layer, $94

SG Says: Sometimes simple is best. This light pink pair from Marine Layer is just the right length, with a stylish drawstring for casual comfort. An absurdly stretchy boxer brief lining means you can easily go from sand to the street, while a zipper stash pocket ensures your phone doesn’t fall out.

Basically everything you could want on a beach day…except margaritas. You’ll have to get those yourself.

7. OAS, $100

SG Says: When you think of Sweden, you probably don’t think fun and funky swimwear.

OAS is looking to change that.

Expect to find sharp, Scandinavian design infused into breezy, warm weather fabrics. Perfect for summer-ready style.

8. Lacoste, $85

SG Says: Just gonna say it…a red pair of swim trunks is a must in every guy’s summer style arsenal.

If you’re not going to spring for Orlebar Brown’s Bulldog style (an SG Hall of Famer if there ever was one), the Lacoste pair above makes for a great affordable alternative.

The recycled quick-dry taffeta (which is smooth, very light-weaved fabric) offers a slightly shiny finish, topped by that iconic crocodile embroidered on the thigh.

9. Target, $25

SG Says: This 7″ striped style comes in big and tall and standard sizing.

We stan an inclusive retailer!

Just know that Target’s swimwear always goes fast in the summer, despite being sold in a bunch of different colors and patterns. So, shop ’em while you can!

10. Chubbies, $79

SG Says: We’ve come a long way on Chubbies here at SG HQ.

Mostly from “No” to “…Yeah, sure, okay, why not!”

This light blue 5.5″ style is super-affordable and totally stylish.

11. Old Navy, $29

SG Says: Count this inexpensive style from Old Navy as a “Throw ’em in your car or weekend bag to have just in case” pair.

12. Wellen, $78

SG Says: Sometimes a funky l’il pattern is just what you need. We like the blue and orange color scheme here that looks cool, not over the top.

13. lululemon, $78

SG Says: If you thought Team SG was ready to let go of our love affair with short shorts on guys…well, think again.

14. American Eagle, $39

SG Says: Swim trunks that look as good on the street as they do on the beach, with a lined interior and a on-trend 5″ inseam.

15. Duvin, $69

SG Says: Swim trunks are the epitome of versatility.

You have options when it comes to waistband, length, fabric, and never-ending patterns.

This throwback style from Duvin ensures you’ll look distinct from every other guy at the neighborhood pool.

We love the washed-out color giving a cool, lived-in look.
