Factors to Consider in Picking the Best Boardshorts Liners – Buying Guide

Boardshorts liners are far different from regular underwear for water sports, specifically for surfing. Most boardshorts liners are made of high-quality and quick-drying materials. Here are other things you need to look for in a boardshorts liner.

Antimicrobial Lining

Long-term smells and damage to shorts are possible. It isn’t often that you go for a swim and hang it up to dry instantly. Some people put them in a bag on their way home. This after swim behavior allows for bacteria and germs to accumulate. For this reason, the antimicrobial lining is essential.

This feature fights against harmful bacteria and eliminates the chance of molds and the smell of sweat.

Rapid Drying

Since your liners will be under your boardshorts, you would want to make sure they dry just as quickly as them. Some boardshorts liners are made of high-quality materials that dry faster, if not as soon as your boardshorts.

Going for quicky-dry boardshorts liners is essential since your body will almost always be wet in water activities. If they aren’t quick-drying, it may cause chafing or itching problems. In addition, your body can be sick if it is wet for a long time.

Seamless Fit

Boardshorts liners fit snugly, unlike your regular underwear. They stick as close to your body as possible. Most of the time, they won’t have drawstrings or heavy elastic waistbands. Be sure to get one that fits perfectly to keep you from pulling and tugging while in the waters.

Do Not Pick Cotton

Cotton in water means trouble. These two just don’t mix. Avoid wearing anything made of cotton underneath your boardshorts liner.

Cotton doesn’t dry as quickly as you need them to. As a result, you will get stuck wet or, even worse, chaffed from all the wetness. Also, since cotton holds water, they could be heavier than your boardshorts which isn’t such a good sight to see.


Size is another factor you should never forget when picking a boardshorts liner. No matter what you will use it for, you need to ensure you get the correct size.

You don’t want to be uncomfortable if it turns out to be too tight or too loose. This just might hinder your performance instead.

It would help significantly if you take your measurements and research the liner in question to see if it fits true to size. Also, while drawstrings aren’t popular in boardshorts liners, you may want to look for one that has to help you adjust if needed.

Why Don’t Board Shorts Have Liner?

As the name suggests, boardshorts are called as such based on their use in aquatic sports that use a board, such as surfing.

When you surf, you wouldn’t want any extra fabric to get in the way of your movements. But, it is also the same reason you should wear one. With the many actions you do while surfing, you need an undergarment to hold and keep things in place.


Many water sports enthusiasts prefer boardshorts liners. They are comfortable, easy to wear, and keeps everything in place. They offer more benefits to your performance than regular underwear or swim trunks.

Remember to keep the liner’s length just above where your boardshorts come to. This leaves you from worrying about chafing or rashes from your legs rubbing together.
