Find Your Size
European sizes are based on your child’s height in centimeters. Because kids of the same age can be different sizes, height is the best guide for fit.
Enter your child’s height in inches, and we’ll show the closest CM size range. This correlates to the first number in the size option. ie: 98 or 122. If CM sizing is not provided, simply choose the age provided.
💡 Tip: These are general guidelines. Always check specific brand size charts when possible, as sizing can vary between manufacturers.
Product Description
Lightly insulated waterproof toddler rain suit with welded seams, made for cold rain, puddles, slush, wet snow, and chilly outdoor adventures.
The Reima Rapakko Lightly Insulated Rain Suit is made for those in-between weather days when it’s chilly, wet, and far too much fun outside to stay indoors. This practical all-in-one gives little explorers waterproof coverage for puddle jumping, muddy playgrounds, wet trails, and slushy adventures.
With a 4/4 waterproof rating, water column of over 10,000 mm, and fully waterproof welded seams, Rapakko is designed for active outdoor play in very wet conditions. Light insulation adds comfortable warmth for chilly days and moderate frost without turning this versatile rain suit into a heavy winter snowsuit.
From rainy preschool mornings to backyard puddles and family walks through wet snow, Rapakko helps simplify dressing for changing weather and keeps little adventurers ready to splash, climb, explore, and make the most of the day outside.
