If you have a baby or toddler who loves being outdoors, finding the right clothing can make a huge difference to how comfortable they are throughout the day.
A good baby sun shirt should do more than simply look cute. When you're heading to the beach, going fishing, spending a day on the boat, camping or exploring the backyard, you want clothing that helps keep your little one covered while remaining lightweight, breathable and comfortable enough to wear for hours.
At Little Fisho, we created our outdoor clothing range after discovering just how difficult it was to find practical sun-safe clothing for babies and toddlers that was designed for the kinds of adventures our family loved.
So, what should you look for when choosing a baby sun shirt?
What is a baby sun shirt?
A baby sun shirt is a lightweight top designed to provide additional coverage from the sun while babies and toddlers are enjoying time outdoors...or even better, a baby onesie with full body coverage!
Unlike a regular cotton T-shirt, a purpose-designed sun shirt can provide greater coverage through features such as long sleeves, lightweight technical fabrics and comfortable designs made for active outdoor use.
For babies and young children, clothing is an important part of a broader sun protection approach, alongside shade, hats and sunscreen on exposed skin.
Why choose a long-sleeve baby sun shirt?
Babies have delicate skin, and little arms can spend hours exposed to the sun when you're outside.
A long-sleeve baby sun shirt provides additional coverage across the shoulders and arms, which can be particularly useful for outdoor activities where you're away from shade.
They're especially handy for:
- Fishing trips
- Beach days
- Boating
- Camping
- Hiking and bushwalking
- Outdoor play
- Family holidays
- Days at the park
For families who spend long periods outdoors, having a dedicated sun-safe top in the nappy bag can be just as useful as carrying sunscreen and a hat.
What should you look for in a baby sun shirt?
Not all children's outdoor clothing is designed with the same purpose in mind. When choosing a baby sun shirt, consider the environment your little one will be wearing it in and how active they'll be.
Lightweight, breathable fabric
Babies can become uncomfortable quickly in hot weather, particularly in Australia's warmer climates.
Look for lightweight fabric that allows airflow and doesn't feel heavy against the skin. Breathability is particularly important if your little one will be wearing their sun shirt for several hours at a time.
Quick-drying fabric
If your family spends time around water, quick-drying fabric can be a huge advantage.
Whether your little one gets splashed while fishing, crawls through wet grass or spends the morning on the boat, quick-drying clothing is easier to manage than heavy, waterlogged fabric.
Good coverage
A baby sun shirt with long sleeves can provide more coverage than a traditional short-sleeve T-shirt.
For particularly active outdoor adventures, you may also want to consider clothing that provides coverage across the legs as well as the upper body, like our Little Fisho UV Defender Onesie which helps protect arms, legs... and even hands and feet!
Comfortable movement
Babies don't sit still for long.
Whether they're crawling around the campsite, playing on the sand or exploring the boat, outdoor clothing needs to allow plenty of movement without feeling restrictive.
Practical features
The little details can make a surprisingly big difference when you're out with a baby.
Features such as easy openings, comfortable seams and practical zips can make getting dressed, changed and undressed much easier when you're away from home.
Baby sun shirt vs baby sun suit: which is better?
It depends on what you're doing.
A baby sun shirt is a great everyday option when you want additional coverage across the upper body while keeping your baby's outfit simple.
A baby sun suit, on the other hand, can provide greater overall coverage and can be particularly useful for long days outdoors.
For example, if you're spending an afternoon at the park, a long-sleeve baby sun shirt might be all you need alongside appropriate bottoms.
But if you're heading out fishing, camping or boating for the day, a full-body baby sun suit or baby fishing onesie can provide coverage across the arms and legs as well.
At Little Fisho, we designed our UV Defender Onesie specifically for these kinds of adventures.
Why we created the Little Fisho UV Defender Onesie
Little Fisho started with a problem I experienced myself.
While on maternity leave in Port Douglas with my daughter Kyra, I struggled to find clothing that would keep her covered from the harsh Queensland sun and mozzies without becoming hot and uncomfortable.
Our family loved fishing, boating, camping and spending time outdoors, and I didn't want becoming parents to mean giving up the lifestyle we loved.
I couldn't find the product I was looking for, so I decided to create it myself.
The result was the Little Fisho UV Defender Onesie.
Designed for babies and toddlers, it combines the coverage of a baby sun suit with practical features designed specifically for outdoor adventures.
It features:
- Full-length arms and legs
- Lightweight, breathable fabric
- Quick-drying material
- Fold-over hands and feet
- A vented mesh back panel for additional airflow
- A two-way zipper for easier nappy changes
- A classic collar
- Real pockets for little outdoor explorers
It's designed to be worn for everything from fishing and boating to camping, beach days and everyday outdoor play.
Baby sun protection for fishing, boating and beach days
One of the biggest reasons parents search for a baby sun shirt is because they're looking for clothing that can keep up with their family's lifestyle.
A day outdoors with a baby doesn't always mean sitting quietly under an umbrella.
You might be moving between the boat and the jetty, chasing a toddler along the beach, setting up camp or spending hours beside the water.
That's why we believe children's outdoor clothing should be designed around real adventures, not just occasions.
A good baby sun shirt or baby sun suit should be comfortable enough that your little one can wear it while they crawl, play, explore and discover the outdoors.
Don't forget the rest of your baby's sun protection
Sun-safe clothing is just one part of protecting little ones outdoors.
For Australian families, it's important to combine clothing with other sun protection measures such as:
- Seeking shade where possible
- Wearing a broad-brimmed hat
- Applying sunscreen to exposed skin as recommended
- Planning outdoor activities around the sun where practical
- Taking regular breaks from direct sunlight
- Keeping babies comfortable and hydrated in hot weather
No single piece of clothing replaces a complete sun protection strategy. Instead, purpose-designed outdoor clothing can be another practical layer between your little one and the elements.
From baby sun shirts to little outdoor adventures
We created Little Fisho because we didn't want having children to mean giving up the adventures we loved.
We wanted our daughter to grow up fishing, camping, boating, exploring and experiencing all the things that made our weekends special.
That's still what Little Fisho is all about today.
Whether you're looking for a baby sun shirt for everyday outdoor play, a baby sun suit for the beach, or a baby fishing onesie for your next family fishing trip, our goal is to make it easier for little ones to join in from the very beginning.
Because outdoor adventures shouldn't have to stop when you have kids.
Sun safe fun from day one.
