Water days are some of the best days of childhood, pool afternoons, beach mornings, splash pad runs, cottage weekends, and vacations where kids seem to stay damp from breakfast to sunset. They are also the days when getting dressed can feel strangely complicated.
Parents are often trying to figure out the same few things. Is a swimsuit enough? Should a child wear a rashguard? Is a sun shirt different? What makes sense before and after swimming? And what is the easiest way to make coverage feel practical without overcomplicating the day?
The short answer is this, the best clothing for water days usually starts with a UPF 50+ rashguard, plus an easy layer for before and after water play. The goal is not to pack half a wardrobe. It is simply to choose pieces that make movement, comfort, and coverage feel easier in real life.

What counts as a water day?
A water day is any day where your child will spend a meaningful amount of time around water, especially outdoors. That can mean more than just swimming.
It might include:
- pool days
- beach days
- splash pads
- swim lessons
- lake days or cottage weekends
- backyard sprinkler play
- travel days with hotel pools or resort activities
These are the days when children are often moving between water, sun, towels, snacks, and play without much pause. That is exactly why the right clothing can make such a difference. It helps make the day feel easier, not fussier.
The best clothing for water days
The easiest way to think about water-day dressing is in layers, not in extra steps. Each piece has a role.
1. A UPF 50+ rashguard for swim and splash time
If the day involves swimming or long stretches of water play, a UPF 50+ rashguard is usually the best place to start. It is made for the part of the day when kids are in and out of the water and ordinary clothing is usually the least practical.
A good rashguard helps make upper-body coverage feel more built in. Our UPF 50+ Quarter Zip Rashguard was designed for that kind of use, with a higher neckline, thumbholes for a little extra hand coverage, and a quarter zip that makes it easier to get on and off.
2. A sun shirt for before and after swimming
A sun shirt is a very useful piece for the parts of the day that are not actually spent in the water. Think walking to the beach, eating lunch outside, playing nearby, or heading back from the pool.
This is where an everyday UPF top can make a lot of sense. A piece like the UPF 50+ Thumbhole Crewneck can be helpful when the day includes outdoor time before or after swimming, especially if you want something soft and easy that still feels like real clothing rather than only swimwear.
3. A lightweight cover-up for transitions
Sometimes the most useful piece on a water day is not the one worn in the water, but the one worn around it. A lightweight outer layer can help with cooler mornings, breezy afternoons, travel, or simply the in-between moments when a child is not actively swimming but still outside.
The UPF 50+ Thumbhole Lightweight Jacket works well as an easy grab-and-go cover-up for those transition moments.
Do kids need both a rashguard and a sun shirt?
Not always, but often they serve different purposes.
A rashguard is usually the better choice for the part of the day that is truly about water. A sun shirt is often better for the parts of the day around the water, before swimming, after swimming, or during regular outdoor time that is not fully swim-focused.
If you only want to start with one piece for water-heavy days, start with the rashguard. If your family spends long stretches outside before and after swimming, then adding a sun shirt or lightweight cover-up makes the setup feel much more complete.
What about regular swimsuits or wet T-shirts?
This is where it helps to be precise. Coverage alone is not the same thing as UPF 50+ tested coverage.
A regular swimsuit, an ordinary wet T-shirt, or a top without a stated UPF rating should not be thought of in the same way as a UPF 50+ rashguard or other UPF 50+ tested clothing. That does not mean those garments offer no protection at all. It simply means they are not the same as clothing that has been clearly presented as UPF 50+ tested.
For parents, the easiest rule is this, if the garment is meant to be part of your sun protection plan, look for the actual UPF rating.
A simple water-day outfit formula
If you want the easiest possible setup, this is a strong starting point:
- a UPF 50+ rashguard for water play
- an everyday sun shirt or lightweight cover-up for the parts of the day around the water
- a hat where practical
- sunscreen on exposed skin
That combination works well because it is realistic. It gives children freedom to move, keeps pieces easy to reach for, and helps sun protection feel like part of the day rather than a separate project.

What should parents pack for a beach or pool day?
You do not need a complicated checklist. In most cases, a few thoughtful pieces are enough:
- one UPF 50+ rashguard
- one easy sun shirt or lightweight cover-up
- a change of dry clothes
- a hat
- sunscreen for exposed skin
That kind of small system makes it easier to repeat what works, especially on busy summer days, travel days, and family outings where simplicity matters.
The bottom line
The best clothing for water days is usually not just one thing. It is a small combination of pieces that each help with a different part of the day.
For swimming and splash play, start with a UPF 50+ rashguard. For the moments before and after the water, add a sun shirt or lightweight cover-up. Keep sunscreen for exposed skin, and aim for clothing that feels comfortable enough to wear without a fight.

On water days, the best clothing is the kind that helps make coverage feel easy, comfortable, and part of real life outside.
