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

What do you wear under board shorts? 2
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.

How to solve the chafing problem

This is an easy one. Get something like Body Glide

What do you wear under board shorts? 3
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.

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

What do you wear under board shorts? 4

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.

What do you wear under board shorts? 5
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?

Mack Weldon Stealth Boxer Brief

The best shorts to wear under boardshorts

The Mack Weldon Boxer Briefs are the best shorts to wear under boardshorts. However, they are on the higher end of the price range ($42), but they are great!

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.

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:

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.

Another, cheaper option for swim short underwear

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: DryDudz!

BN3TH Entourage – Make your boardshorts even better

Meet the BN3TH Under Short

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.

What do you wear under board shorts? 12

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.

DryDudz: cheaper underwear to wear under swim trunks and board shorts

What do you wear under board shorts? 13

What are DryDudz? They compression underwear designed to wear underneath your board shorts.

DryDudz Highlights

  • The DryDudz are compression shorts made of both polyester and Lycra (Lycra = Stretch!)
  • They are designed to be worn under swimwear so you can buy swimwear with or without mesh lining.
  • You can Machine Wash or Hand Wash. It’s best to air dry or dry on low heat – I personally air dry.
  • DryDudz now features the new Ecoinn (Eco-friendly + Innovation) Dry-Thru Technology: Wicking only means airflow, the DryDudz compression shorts wick AND provide moisture control.
  • It’s both a performance compression short AND swim liner.
  • They are designed to be worn with the DryDudz Board Shorts (sold separately but retail for about $25).
  • Enjoy Anti-chafing, Irritation-free comfort during any fitness activity.
  • This 4-way stretch short is a perfect baselayer for all outer garments – does not have to be used for only under your boardshorts or swim trunks!

DryDudz Board Shorts, WTF would I need a belt!?

DryDudz, your compression shorts are awesome, but what the heck is going on with your board shorts?

Why do you include a belt with your board shorts? That’s crazy talk, DryDudz!

What others are saying about DryDudz

What do you wear under board shorts? 15

Don’t just take our word for it. Look what other’s are saying on Amazon about DryDudz:

CHRIS: I wear DryDudz under my wetsuit: mainly to get in and out more quickly without dealing with a towel to cover myself (and worry about being naked!) You can’t really wear swim trunks under a wetsuit – it’s too tight… DryDudz works and fits perfectly. It dries so quickly that it is optional whether or not to use it as underwear when you are done. Only thing is, I wish I got DryDudz in all black. What the heck… I’ll just buy a second one.


MIKE: These are great. My bathing suit doesn’t have a liner or mesh. These fit and feel great under the bathing suit. I bought 2 and ended up buying 2 more. I wear O’Neil bathing suits – they dry really quick and having the DryDudz underneath also dry quick great purchase!


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!

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.
