Warm merino wool beanie with soft fleece lining and windproof earpieces for outdoor school, winter walks, and everyday cold-weather play.
Product Description
The Reima Kids Knight Style Winter Hat is made for frosty outdoor school mornings, snowy playgrounds, winter walks, and everyday adventures when little ears need extra protection from the cold. Soft merino wool provides comfortable warmth, while a cozy fleece lining creates an inviting layer for long days outside.
Windproof earpieces add targeted protection around the ears, making the Mystinen especially useful when winter breezes pick up. Its close-fitting winter design stays comfortably around the head and ears while kids run, climb, explore, and make the most of cold-weather days.

Why ODSS Recommends It
We like the Reima Mystinen for kids who need more thoughtful winter ear protection than a basic knit hat provides. The combination of soft merino wool, cozy fleece lining, and windproof earpieces makes it especially practical for cold outdoor school mornings and everyday winter adventures.
It is warm, simple, and made for the kind of winter days when kids are too busy climbing snowbanks, exploring the playground, and following trails through the snow to think much about what they are wearing.

FOUNDED BY WOMEN. BUILT FOR ADVENTURE.
ODSS was started by mothers who saw firsthand how time outside builds resilient, confident kids. What began as helping outdoor schools equip students for all-weather learning grew into a bigger mission: Help families raise resilient, confident kids by making it easier for children to stay outside longer.
Testimonials
For us, the right gear from ODSS supports what we believe most about childhood. When children are able to be outside every day, in all seasons, they become tenacious, confident, and develop an authentic relationship with the land.

Working with Outdoor School Shop has transformed our outdoor school community. Parents love knowing their children are consistently and reliably equipped—and that nothing is forgotten or comes home covered in mud.

Our students get outside in all temperatures and having the right gear makes a world of difference. @outdoorschoolshop has gear appropriate for all seasons, has a directory to search for nature schools, and layering guides to help families know how to dress children for the weather

Ordering bulk with Outdoor School Shop was just as easy and seamless as I had hoped! As we open up a new program, preparing our first group of kiddos for any weather was at the top of our priority list, and ODSS came through with insight, expertise, and the coolest, most dependable gear around! Thank you ODSS!
