For men there is very little modest swimwear on the market, but you can make up a nice outfit from sportswear. T-shirts and 3/4 length shorts are a simple outfit to begin with.

In many countries men are expected to cover the area from their shoulders to their knees, so T-shirts and long shorts are the usual modest male swimming attire.

Improvise for Sun Protection

Many men just improvise and wear T-shirts with jeans or shorts. A long sleeve sports shirt and lightweight pants provide both modesty and sun protection.

Cool Cotton

Cotton shirts and jeans are ideal for warm climates as they dry slowly and keep you cool. Sweatshirts, hoodies or anoraks go well with T-shirt and jeans. They just feel awesome when wet.

Colours

Keep in mind that light coloured T-shirts can be seen through when wet. Wear two T-shirts on top of each other, maybe a short sleeve one over a long sleeve one. Dark colours underneath light colours look good.

People will probably not look twice if you choose to wear your T-shirt in a swimming pool. Many public swimming pools allow T-shirts in the water, but do not allow other street clothes into the pool. Just ask and check the rules of the pool before swimming in your T-shirt.

Your Complete Outfit for Aquatic Fun

Light weight tracksuits cost not much, avoid sunburn, and feel pleasant as they dry in the breeze after you've been in the water.

Matching tops and pants make this a practical outfit on land or in the water for less than €20. The advantage of these outfits is that you can also wear them when you're not swimming.

Choose the unlined variety, so water doesn't collect between the two layers.

Modest Swimming Kit: Tracksuit and Swimwear

Did anyone ever think to ask the question why it is that we feel the urge to insist that a woman cover her breasts at all, but don't insist upon the same thing with regard to men?

I mean if you actually think about it, a woman's breasts and a man's breasts are, by all appearances, identical. Indeed when it comes to breast-size some men beat many women in this particular area (probably much to the chagrin of the former).

It would be nice to find other people who have also taken the time to think rationally and objectively about this peculiar societal double standard.

Personally, I choose to express my individuality and pick swimwear that suits my mood and style. There are so many options if you just widen your swimwear horizon. My preference is a long sleeve swim shirt and long pants as this avoids sunburn and feels right.    Khun Mee, Thailand
