It's all fun and games until your chest gets all messed up. If you're new to the wonders of surfing, odds are you are trying to figure out all that you need before you head out on a wave. One crucial thing to ask is, "how tight should a rash guard be?"

How Tight Should a Rash Guard Be?

Rash guards protect your body from abrasions when you are out on the water. People commonly wear them when surfing, but you can wear them wherever you want to. However, they were designed for surfers to protect their chests from the rough grip of the surfboard.

Now, how tight should a rash guard be is really up to the wearer. Rash guards typically come in two fits, loose and regular/clingy. Both have their benefits and may give you a different experience, but in reality, it is all up to you and what you like more.

If you don't even know what you prefer yet, it might be a good idea to know what's available, what the difference is, and how the fit of a rash guard can affect your performance.

What Does a Rash Guard Do?

As previously mentioned, a rash guard is meant to keep your chest and upper body from abrasions. A surfboard typically has a rough coating on the top. This design helps give your bare feet some traction. However, laying down and finding one's self thrown around can often lead to your chest and arms receiving a brush burn or worse.

That rash guard will make sure that your arms, chest, and stomach are safe. The shirt is also made out of material that won't tear, regardless of how much torture it gets from the waves.

But how tight should a rash guard be? Well, everyone has their tastes and odds are you will see a myriad of different styles out on the water. Some will improve your performance more than others will.

Rash Guard Fits

How tight should a rash guard be depends on your body size and comfort level. In general, there are two fits you can choose from when picking out a surfing shirt -- loose-fitting or the regular/clingy fit.

Now the loose fit may feel more comfortable because it will feel like you are wearing a t-shirt. However, if you fall in the water, it may also feel like you are swimming in a t-shirt. It's not as heavy or cumbersome, but you will find yourself left with excess material.

On the other hand, a clingy, more performance-fit shirt will be tighter around your chest, arms, and stomach. Some people may not like that feeling, but the fact that it will stretch and move with your body is nice, especially when you get out on the water and are having to move around a lot.

However, buying a guard that is too tight can be detrimental to your performance. You do not want something that is going to limit your movement in any way. That can lead to a dangerous situation if you find yourself thrown from your board by a wave.

Be sure to try on a bunch of different styles and fits until you find one that suits you perfectly.

Should you even wear one?

Yes. Rash guards are incredibly important when you are surfing unless you want a chest that looks like Freddy Krueger's face. Rash guards may seem like an annoyance, especially in the hot summer sun, but they help out more than you think.

Not only does a rash shirt help with the surface of your board, but it can also protect your upper body if you wind up between a wave and the surf. That sand is often filled with stones, shells, and who knows what else.

Your rash guard provides a barrier between your skin and any sharp object you may rub against.

These guards can also help out when it comes to keeping sunburn down to a minimum. Sunscreen is a good idea, but wearing a rash guard also puts a barrier between you and the sun.

Rash guards are an essential part of surfing, and knowing how right should a rash guard can save you a lot of headaches and bodily pain. However, one fit will not be the same for everyone. Some like the looser fits more than others, and there is nothing wrong with that.

However, no matter what you like, stay away from unisex fits. Every body shape is different, and the universal fits are never good.
