Kids Waterproof Rain Hat – Reima Rainy – Neck & Ear Coverage

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.

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.

Size Guide

How to measure: Wrap a soft measuring tape around your child's head, just above the eyebrows and ears, where the hat will sit. Use the measurement in centimeters to choose a size below.

Size Head (cm) Head (in) Age XXS 46 18.1 9–12m XS 48 18.8 1–2y S 50 19.6 3–4y M 52 20.4 5–6y L 54 21.2 6–7y XL 56 22.0 7–12y

Measurements and ages follow Reima's hat size chart. Ages are a general guide; head measurement is the most reliable way to choose.

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.
