Kids Waterproof Pull-On Rain Pants – Reima Oja

Sometimes the best outdoor gear is the piece kids can pull on and get back outside. The Reima Oja Kids Waterproof Rain Pants are the easy pull-on alternative to bib-style rain pants, giving older kids simple waterproof coverage for puddles, mud, wet grass, slush, and everyday outdoor school adventures.

Reima rates the Oja for active play in very wet conditions, including heavy rain and wet snow. Welded waterproof seams and a water column over 10,000 mm create a dependable outer layer for the days when sitting on a wet log, kneeling in the mud, or running through a soaked playground is simply part of the plan.

The pull-on design is especially useful for kids who are ready for a simpler pant they can manage more independently. Pull them over everyday clothes when the playground is soaked, add fleece or warm pants underneath on colder days, or use them as an extra waterproof outer layer when winter conditions turn wet and slushy.

That is what we love about good rain gear: it does not have to belong to just one season. By changing the layers underneath, families can use the same waterproof shell through rainy school mornings, muddy fall hikes, spring thaw, and wet snow.

Pair the Oja with the Reima Lampi Rain Jacket for complete upper- and lower-body rain coverage, then add Puro lined rain mittens for cooler wet weather or Kura unlined rain mittens when you want more layering flexibility.

Why Parents Love It

• Made for layering: Pull them over everyday clothes or add warmer layers underneath as temperatures change.

• Built for messy play: A practical choice for puddles, muddy trails, wet playgrounds, outdoor school, and spring slush.

Built for Real Outdoor Use

Wet ground can shorten outdoor play faster than rain falling from the sky. Kids sit, kneel, crawl, climb, slide, and investigate everything at ground level—which is exactly why waterproof pants make such a difference.

The Oja gives kids an outer layer they can pull on when the playground is soaked and then get right back to exploring. Mud can be dug in. Wet logs can become balance beams. Puddles can be crossed instead of avoided.

And when the weather gets colder, simply change what goes underneath. Layer the Oja over warmer pants for chilly rain or use it as additional waterproof coverage when snow becomes wet and slushy.

One simple waterproof layer can help turn weather that might shorten the day into another reason to keep playing.

Oja or Lammikko?

• Choose Oja for simple pull-on coverage: The over-the-waist pant design is a great option for older kids and children who want rain gear that is quick to pull on and off.
• Choose Lammikko for bib-style coverage: The Lammikko extends higher over the body and is especially useful for younger children and extra-messy puddle play.
• Both are waterproof outer layers: Choose the style that works best for your child, then adjust warmth with the clothing underneath.

Build the Rain Kit

Pair the Reima Oja Rain Pants with the Reima Lampi Rain Jacket for an easy two-piece waterproof setup, then choose rain mittens based on the weather.

• Reima Lampi Rain Jacket: The natural waterproof jacket pairing for complete wet-weather coverage.
• Reima Puro Rain Mittens: Choose the lined option for cooler rainy days and wet snow.
• Reima Kura Rain Mittens: Choose the unlined option for milder conditions or flexible layering over warm mittens.

Things to Know

• Pull-on pant: Oja is an over-the-waist rain pant rather than a bib-style design.
• Designed as waterproof outerwear: Adjust warmth by changing the layers underneath.

• Boot straps by size: Detachable boot straps are included through size 8Y. Sizes 9Y–12Y do not include boot straps.

• Current size range: 4T–12Y.

Why ODSS Recommends It

Rain pants are one of those simple pieces of gear that can add a lot more outdoor time to a child's day. The Oja lets kids sit on wet ground, kneel in mud, splash through puddles, and keep exploring when everything outside is soaked.

We especially like this pull-on style for kids who have outgrown—or simply do not need—the extra bib coverage of the Lammikko. It is quick, uncomplicated, and easy to layer over the clothes they are already wearing.

Pair Oja with the Lampi Rain Jacket and either Puro or Kura rain mittens, add boots, and you have a practical wet-weather system made for outdoor school, muddy trails, wet snow, and longer days outside.
