Children move more, sweat more and care less about staying dry – which makes the right rain gear more important for them than for adults. With the right pieces, they can play freely outdoors whatever the weather.

Common mistakes parents make when dressing children for wet weather
Children regulate body temperature less effectively than adults and cool down faster when their clothes get wet. At the same time, they rarely stop playing because it's raining – they run, jump in puddles and sit on the ground. That places high demands on materials and durability.
The goal isn't to keep children indoors in bad weather. It's to dress them so they can be outside without freezing or getting soaked.
Just like for adults, layering works best – but for children the key is to keep it simple and make sure the pieces are easy to put on and take off.
Three layers to start from:
Base layer – sits closest to the skin and keeps the body dry from the inside. Choose merino wool or synthetic, never cotton.
Mid layer – provides warmth. A thin fleece works well and is easy to remove indoors.
Rain suit – protects against rain, wind and slush. A rain suit with both jacket and trousers gives the best protection for active children.
The more active the child, the more important it is that the base layer transports moisture away – otherwise clothes quickly become cold and clammy from the inside.
Should Children Have Rain Gear or Shell Clothing?
It's a common question – and the answer depends on the child's activity level and the weather conditions.
Rain gear prioritises waterproofing. It's designed to keep out rain and slush and works best when it's really pouring, when children play in puddles or sit on wet ground. The downside is that it often breathes less well, which can make active children warm and sweaty from the inside.
Shell clothing is windproof and water-repellent but not fully waterproof like classic rain gear. It breathes better and allows more freedom of movement, making it an excellent choice for active children in light to moderate rain, wind and cold. Many families use shell clothing as their everyday outdoor layer and save rain gear for the really wet days.
When to choose which:
Rain gear: heavy rain, puddles, wet ground, low-activity situations
Shell clothing: light to moderate rain, wind, active play, longer outdoor trips
For children who are very active outdoors, a good shell suit is often a more versatile choice than a classic rain suit – it gets used more days of the year and provides better comfort in movement.
Not all children's rain gear is the same. Here's what actually makes a difference:
Waterproofing and seams – choose garments with taped seams to prevent water seeping in at the stitching. Children's clothing takes more wear and needs to stay watertight even after many washes.
Breathability – children move a lot and rain gear that doesn't breathe at all makes them quickly warm and sweaty from the inside. Choose materials with good breathability.
Fit and freedom of movement – rain gear that's too tight restricts movement. Choose a model with a little extra room for mid layers and free mobility.
Simple fastenings – velcro and simple zips are easier for children to manage themselves. It encourages independence and saves time.
Durability – children's clothing takes a beating. Choose materials and construction that can handle tough use, mud and repeated washing.
Footwear determines how long a child enjoys being outdoors in bad weather. Cold, wet feet end playtime far earlier than necessary.
Rubber boots – the best choice for slush, puddles and wet ground. Choose a model with good grip and ideally a lining for extra warmth on cold days. Make sure the boots fit well – boots that are too loose make it hard to run and climb.
Waterproof boots & hybrid boots– good for slightly drier rainy weather and if the child is more active on varied terrain. Provide more support and grip than rubber boots.
Always choose wool or synthetic socks with rain gear. Cotton socks absorb moisture and make feet cold even in waterproof shoes.
Cotton in any layer. Cotton retains moisture and dries slowly. A wet cotton t-shirt against the skin cools a child down quickly, no matter how good the rain gear is on the outside.
Rain gear without breathability. Cheap rain gear made from completely sealed material may protect against rain but not against sweat from the inside. The result is wet clothing whether it rains or not.
Too tight a fit. Rain gear that's too snug restricts movement and doesn't leave room for mid layers. Children move more freely when clothing fits well.
Regular cotton socks in rubber boots. Cotton socks and rubber boots are a bad combination – moisture stays trapped and feet get cold quickly.
1. Skipping the base layer. It's easy to put rain gear straight over a cotton t-shirt. But without a moisture-wicking base layer, sweat builds up and the child gets cold quickly once activity slows down.
2. Buying rain gear that's too small. Children grow fast, but rain gear that's too tight restricts movement and doesn't leave room for mid layers. Go a size up to allow for growth and layering.
3. Underestimating the importance of rain trousers. Many people only think about the jacket and forget that legs and the lower body get at least as much water exposure – especially when children sit, crawl and run through puddles.
Base layer: Long-sleeved top in merino wool or synthetic
Mid layer: Thin fleece or quilted jacket
Outer layer: Waterproof rain jacket and trousers with taped seams, or a shell suit for active play in lighter rain
Footwear: Rubber boots with grip, ideally lined for cold weather
Socks: Wool or synthetic – never cotton
With that in place, children can be outside for hours without freezing or getting soaked.
What should children wear when it rains?
A moisture-wicking base layer, a warm mid layer and a waterproof rain jacket and trousers. Complete with rubber boots and wool socks for the best protection.
From what age can children wear rain gear?
Rain gear is available for children from infancy. Rain mittens and rain suits are common from around 1–2 years, while a two-piece rain suit with separate jacket and trousers suits children who are more active.
How waterproof does children's rain gear need to be?
For active children playing outside in heavy rain and slush, rain gear should have taped seams and a water column of at least 5,000–8,000 mm. Lower ratings may be sufficient for lighter rain and shorter outdoor trips.
How do you wash children's rain gear?
Follow the garment's care instructions – most rain gear is washed at 30–40°C without fabric softener. Tumble drying on low heat or tumbling with tennis balls can help reactivate the water-repellent finish.
Do you need to re-proof children's rain gear?
Yes, over time the water-repellent finish decreases. Re-proof regularly with a spray designed for technical textiles to maintain the garment's protective properties.
What size rain suit should you buy for children?
Go a size up to allow room for mid layers and the child's growth. Rain gear that's too tight restricts movement and doesn't leave room for extra layers on cold days.
Can children use the same rain gear in autumn and spring?
Yes, in most cases. Adjust the mid layer to the temperature – a thicker mid layer in autumn and a thinner one in spring. The rain gear itself doesn't need to change between seasons.
What is the difference between shell clothing and rain gear for children?
Shell clothing is windproof and water-repellent but not fully waterproof – it breathes better and suits active play in light to moderate rain. Rain gear is fully waterproof and works best when it's raining heavily or when the child is in wet and muddy conditions. Many families choose to have both and adapt to the weather and activity.
