It’s obvious for most people that swim trunks are not made from the same material as you normal clothes. The material used in swim trunks have other characteristics, better suited for swimming. But what material are swim trunks made of? The most common standard material for swim trunks is Polyester, Nylon and Polybutylene Terephthalate (PBT). Not every swim trunk is made with the same material. They are also quite an advancement in clothing wear as they are primarily made from synthetic materials blended. There are some uncommon trends to make swim trunks out of cotton, but that is from an earlier time, where some of the earliest swim trunks ever were made out of wool, as the synthetic fibres were simply not available at the time!

In short, board shorts are made of similar materials to swim trunks. This means they are primarily made of a polyester blend with elastane or with nylon. Both materials are very popular, and the shortcomings of nylon (no UV protection and not chlorine friendly) are not too relevant as they are worn in more casual wear on the beachside or in tropical locations. What holds them up is a completely different matter. They can have a Velcro enclosure, which is sometimes uncomfortable, a form-fitting neoprene to secure some parts or a lace-up front enclosure. The last item is the most common as that is usually a triple lace up for ultimate protection so that no waves will ever be strong enough to take down those board shorts! In addition, some board shorts do not come with a power mesh, meaning they are not like traditional swimwear and can be used in a more casual setting.

These are more than just swim trunks, but they can usually cover your entire body so that it is protected as well as applying sunscreen to your body. Keep in mind that these UV protected fabrics can lose their integrity due to constantly washing them. Also – darker colours offer better overall protection but have the issue of making you warmer as well. Finally – a dry UV swimsuit will always offer better overall protection than a wet one. You can look at full-body UV protection swimsuits which are usually called rash guards. These rash guards are actually full-body swim shirts and shorts made with similar polyblend material as common swim shorts. They are more about protection than aesthetics at times and are usually made with a duller matte-like consistency. These are perfect for those that are concerned about high UV radiation, or those that will be surfing for several hours and prefer a looser more casual fit than a full body tight neoprene wetsuit.
