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.

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!
