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.

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.
