What to wear under board shorts: Your options

Like anything in life, there’s not just one option of what to wear under board shorts (or swim trunks without a mesh linger) we’ve got a couple for you!

Your First Option: Free as a bird

No lining? No problem! What to wear under board short: the first option is really easy.

You may be thinking to yourself, “Can I wear nothing under my board shorts?” The answer is YES, you can wear nothing under your board shorts – you can be as free as a bird.

Just like you can chose not to be wearing underwear all the time – you can not wear anything at all.

The problem with not wearing underwear under board shorts…

The only issue is that this can leave little to the imagination if you know what I mean. 😉 Also, playing with kids, I like to put another layer (mesh liner or otherwise) in between the world and my business. 🍆

Most surfers do go commando (aka don’t wear any underwear) with their board shorts. But, let’s be real. How many people wearing board shorts are really surfing? Most of them are used around community pools and BBQs.

You’re just using it when you might get wet or take a dip – not hitting the waves and surf.

The other problem is that some shorts are not quick dry enough. You don’t want to be outside and soggy wet. You need shorts (and potentially underwear) that will dry quickly.

How to solve the chafing problem

This is an easy one. Get something like Body Glide

Use some Body Glide on the areas of skin that could get wet and chafe.

This invisible balm made with natural ingredients, protects you from chafing during intense and long-distance workouts, or anytime that you may chafe – especially in the water.

No one wants to chafe on their beach vacation and still look good in your natural bathing suit.

What to wear under your board shorts: the worst (and 2nd option)

Before you go off thinking, “I’ll just wear underwear under my board shorts…”

Cotton + Water = Trouble

The second option isn’t a good one: just wearing regular boxers under your board shorts. People do it – but one thing is true: Cotton and Water Does Not Mix. Don’t wear regular cotton boxers or wear regular underwear with board shorts. I promise that you’ll regret it.

Can you wear regular cotton boxers under board shorts? Sure! However, we don’t recommend it.

Cotton doesn’t dry very fast. It can leave you wet and – even worse – chaffed from all the wetness. You get the picture. We don’t need to go any further.

It doesn’t matter if you wear old-school tighty-whiteys or more modern boxers under your swimming clothes. Just stay away from anything that is cotton.

Of course, the easiest thing would be to simply buy swimwear with built-in lining, but I know they don’t always have the very best styles. We tried Chubbies (watch our rapid Chubbies Review) and they are just so, so.

There are a lot of other brands out there these days. We hope to be trying more in the very near future!

Just don’t mix cotton with swimwear. Deal?

Should you wear underwear with swim trunks?

With swim trunks: no way. The built-in mesh lining + underwear is a recipe for disaster. However, board shorts are another question. There are more and more swim shorts these days coming out without a mesh lining, too.

If you’re wondering, “do guys wear underwear under swim trunks?” or “do guys wear underwear with swim trunks?” Not usually with swim trunks and sometimes with board shorts.

The best option: What to wear under board shorts

Let me give you a quick buying guide on what to wear under and swim shorts that don’t have a mesh lining.

The best option to wear under board shorts: Amphibious Underwear
Mens swim trunks without mesh? Something like board shorts. The best option to wear under board shorts: Amphibious Underwear!

This may be surprising – but there is actually underwear designed to be worn under boardshorts. And there are swimsuits without mesh, designed that way.

There is also underwear designed to be worn under boardshorts. This underwear is the best option of what to wear under boardshorts or swim trunks without a mesh liner.

The Best Quick dry underwear for swimming

It was surprising for us, too. It was actually really hard to find (more on than in a moment). But there are specific pairs of undies designed just for this purpose: wearing under boardshorts or swim trunks – either just for looks or while swimming.

If you want to wear underwear under board shorts or swim trunks, look at these.

The best option, in my humble opinion, is the Mack Weldon Stealth Underwear (you may have noticed we really like Mack Weldon – read our full Mack Weldon Review). This underwear is designed to be worn under your swim shorts and a great option. They retail for $38 and are so comfortable that you won’t even notice them.

Even better, they dry super fast after you take a dip in the pool or the ocean. They are the perfect pair of quick dry underwear for swimming

The perfect fast drying underwear for swimming

The Mack Weldon Stealth Boxer Brief also has what is called “Body Mapping Technology” – this supposedly (I have no way to prove this, but have no reason to not believe it) is based on your body’s reaction to physical activity.

The Stealth Underwear is also seam-free to help with comfort.

No branding on waistband

I also like the subtle colors with no branding on the waist band:

The best quick dry underwear for swimming and my choice for swim trunks without mesh lining.

I’ve been wearing Mack Weldon’s Amphibious underwear for years now when wearing swim shorts and they are awesome The Mack Weldon Stealth Underwear is brand new and is even better!

If $38 is too much to spend on underwear under your swim shorts, I get it.

Why it’s tough to find cheaper options

A quick warning on searching for “Swim Trunk Underwear” on Amazon. You’ll find a lot of things you probably are not searching for:

NOT what I was looking for!

I didn’t want to wear underwear to the beach or pool – I wanted something to wear under your board shorts. After many, many uncomfortable minutes on Amazon, I found several different solutions: BN3TH.

What to wear: BN3TH Entourage

Meet the BN3TH Under Short, if you wear it, it’s almost like compression lined swim trunks.

BN3TH says, “your favorite boardshort just got better.”

BN3TH was nice enough to send us some BN3TH Entourage Undershorts to review. What are they? They are a great pair of undershorts.

I won’t take it personal, but BN3TH’S “MYPACKAGE” is a super-large – but is still really comfortable.

I’ll post my full review of the BN3TH Boxers shortly and I really liked them! They are available on Amazon for about $35 and are a great value.

My biggest concern with undershorts is making sure they stay on, especially with the little ones climbing all over me at the pool. The BN3TH Entourage Under Shorts stayed on PERFECTLY.

The only thing that I didn’t love was the super bright colors. I typically like dark/neutral colors without a lot of patterns.

Compression Shorts: Another alternative to wear under swim shorts

You can also wear compression shorts underneath swim shorts and board shorts. However, your results will vary greatly. Something like these Vuori Compression Shorts could work really well, however, they are still more expensive than the Mack Weldon Stealth Boxer Brief.

A quick disclaimer on what do you wear under board shorts

I’m not a professional athlete or Michael Phelps wanna-be. I’m a dad of two that likes comfort and no looking obnxious. None of the items listed are for someone trying to win a gold medal swimming or high-diving. The option listed here aren’t for the high-performance athlete.

However, they are designed to keep you comfortable and free from any embarrassment!

Other Products to Check Out

Based on what you are looking for, we’ve tested out other products that can be used as hybrid shorts (check out these Hybrid Shorts) or even something like the lululemon swim trunks.

Board Shorts With Liners

I’ve seen a couple of pairs of board shorts recently with liners.

I think this kinda defeats the purpose.

However, they say these board shorts with liner were, “made for 3 x world champion, Mick Fanning.”

I may not be a world-champion surfer, but I know what I like and don’t like.

What to wear under swim shorts without mesh: the final verdict

There are a lot of options, ranging from nothing to underwear designed specifically to be worn under swim trunks and board shorts. The great news is that without a built-in liner, the choice is up to you! And you can go free bird one day and wear Amphibious Underwear or DryDudz the next day.
