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
The Reima Parvin Toddler Merino Wool Jumpsuit is a cozy one-piece layer made for chilly mornings, outdoor school, winter adventures, and comfortable days at home. Soft merino wool helps regulate temperature as little ones move between activities, while the brushed interior adds extra warmth without turning winter layering into a bulky routine.
Designed to work indoors or as a mid layer beneath outerwear, the Parvin keeps warmth comfortably together in one easy piece. It is especially useful for toddlers who are constantly bending, crawling, climbing, and exploring, with no separate top and bottom to shift apart while they move.
Why Parents Love It
- Soft merino wool: Reima uses merino wool for comfortable warmth and natural temperature regulation.
- Brushed for extra warmth: The interior is brushed to create a warmer, cozier feel for cold-weather layering.
- Easy one-piece coverage: The jumpsuit keeps the torso and legs covered in one simple layer as toddlers move and play.
- Works indoors or outside: Wear it on its own indoors or as a warm mid layer beneath winter outerwear.
- Made for everyday movement: A practical option for outdoor school, stroller walks, cabin days, winter travel, and everyday exploring.
Built for Real Outdoor Use
Toddlers rarely stay in one position for long. They are squatting to inspect pinecones, crawling through forts, climbing playground steps, and stretching in every direction once the adventure starts. A one-piece mid layer helps keep warmth where it belongs without separate layers riding up or leaving gaps.
The Parvin combines that practical coverage with the comfort of soft merino wool and a brushed interior. Layer it beneath a snowsuit or weather-protective shell for cold outdoor days, or use it as a cozy everyday layer when temperatures are cool but full winter protection is not needed.
Things to Know

Why ODSS Recommends It
The Reima Parvin is one of those simple layers that can make cold-weather routines easier. We like the one-piece design for keeping toddlers comfortably covered while they crawl, climb, bend, and explore, and the soft merino wool brings natural temperature regulation to changing activity levels.
It works especially well beneath snow gear for outdoor school and winter adventures, but it is just as useful for cool mornings at home, travel days, and family weekends outside. The brushed interior adds that little bit of extra warmth that makes it an easy layer to reach for again and again.
