Waterproof kids’ rain hat with welded seams and extended ear and neck coverage for outdoor school, puddle days, and wet-weather adventures.
Product Description
A complete rain kit should let kids forget about the rain and get back to playing. The Reima Rainy Kids Waterproof Rain Hat is the finishing piece that helps keep little heads, ears, faces, and necks covered through puddle jumping, muddy outdoor school mornings, creek walks, and long days spent exploring in the rain.
Made from waterproof material with welded waterproof seams, the Rainy is rated by Reima for very wet conditions, including active outdoor play in heavy rain and wet snow. Its lightweight, unlined construction makes it an easy outer layer that can be worn through changing seasons.
The extended shape provides coverage around the ears and down the back of the neck—areas that can easily end up exposed when kids are bending, climbing, digging, and looking down into puddles.
We especially love a dedicated rain hat for active outdoor play because kids can turn their heads, look down, climb, and explore while keeping waterproof coverage around the head and neck. It is a small piece of gear that can make a surprisingly big difference on a long, wet day outside.
Pair it with the Reima Lampi Rain Jacket and Lammikko or Oja Rain Pants, then add Puro or Kura Rain Mittens and waterproof boots for a complete wet-weather system.
Why Parents Love It
- Waterproof for serious rain: Reima rates the Rainy for active outdoor play in heavy rain and wet snow.
- Welded waterproof seams: The seams are welded to help keep rain from working through the hat.
- Extra head-and-neck coverage: The shape is designed to protect the ears, neck, and face from rain.
- Lightweight and unlined: Easy to use through changing seasons and simple to add over other weather-appropriate layers.
- Made for active kids: A practical choice for puddle jumping, mud play, outdoor school, rainy hikes, and everyday wet-weather exploration.
Built for Real Outdoor Use
Kids do not stand still under an umbrella when it rains. They bend over puddles, look for worms, climb wet logs, collect leaves, dig in mud, and run from one discovery to the next.
The Rainy hat is made for that kind of movement. Its extended coverage helps protect the ears and back of the neck while kids are busy looking down, turning their heads, and getting fully involved in outdoor play.
It is also easy to keep with the rest of the rain gear. Jacket, pants, boots, mittens, hat—and suddenly a rainy forecast becomes another invitation to head outside.
Complete the Rain Kit
- Reima Lampi Rain Jacket: Waterproof upper-body coverage with welded seams.
- Reima Lammikko Rain Pants: Bib-style waterproof coverage for younger kids and especially messy puddle play.
- Reima Oja Rain Pants: Simple pull-on waterproof pants for older or more independent kids.
- Reima Puro Rain Mittens: Lined waterproof mittens for cooler wet-weather days.
- Reima Kura Rain Mittens: Unlined waterproof mittens for milder weather or flexible layering.
- Reima Rainy Rain Hat: Waterproof coverage for the head, ears, face, and neck.
Things to Know
- Unlined: The Rainy is a lightweight waterproof outer layer without built-in insulation.
- Designed for very wet weather: Reima rates the waterproof fabric for active play in heavy rain and wet snow.
- Check sizing carefully: A number of current Reima customers report that the hat fits smaller than expected, so we recommend checking the size chart rather than relying only on your child’s age.
- Current size range: Reima currently offers the Rainy from 9–12 months through 7–12 years.

Contact ODSS for bulk availability, sizing support, and help building complete rain kits for your group.
Why ODSS Recommends It
Once you have the jacket, pants, boots, and rain mittens covered, a waterproof rain hat is the piece that finishes the system.
We love the Rainy because it gives kids waterproof coverage around the head, ears, and neck while still letting them move, look down, turn their heads, and get completely absorbed in outdoor play.
It is small enough to keep tucked with the rest of the rain gear but useful enough to earn a place on every outdoor-school checklist. Add it to the Lampi, Lammikko or Oja, and Puro or Kura mittens for a rain kit made for puddles, mud, wet snow, and longer days outside.

Ordering bulk with Outdoor School Shop was just as easy and seamless as I had hoped!
