High-waisted waterproof rain bibs for outdoor educators, with stretch PU fabric, welded seams, elastic suspenders and a chest pocket.
Product Description
The Helly Hansen Impertech Sanitation Bib is a fully waterproof rain bib for teachers, staff and grown-ups who kneel, crouch and sit in wet ground right alongside the kids.
Made from the same stretch Impertech PU fabric and MicroWeld seams as the Impertech Rain Jacket, it covers from chest to ankle. Wear it over the warm pants you already own, and add the matching jacket for full rain protection.
Why Parents Love It
- Waterproof barrier: Helly Hansen describes the Impertech fabric as fully waterproof, with MicroWeld seams for watertight construction.
- High-waisted coverage: the bib design helps keep rain and mud out at the waist when you bend, reach and kneel.
- Moves with you: full stretch fabric makes squatting at the creek or crawling into a fort easier.
- Adjustable fit: elastic suspenders plus snap adjustments at the waist and hem help dial in the fit over layers.
- Elastic at the ankles: helps keep splashes out of your boots.
- Chest pocket: a right-side pocket with a hook-and-loop closure keeps small essentials close.
Built for Real Outdoor Use
Kids do not stay standing on wet days, and neither do the grown-ups who teach them. These bibs are made for kneeling in garden beds, sitting on damp logs during circle time and helping little ones through muddy trails.
A soft circular knit backing makes them more comfortable over your layers, and the workwear build is made for daily use through a long, wet season.
Things to Know
- Fit: men's sizing with a high-waisted cut. Check the size chart, and leave room for warm layers underneath.
- Not a breathable shell: PU fabric keeps rain out but traps more moisture than a breathable membrane, so you may feel damp during hard exertion.
- No insulation: layer warm pants underneath on cold days.
- Care: rinse and wipe clean when possible, and wash only when needed.

Why ODSS Recommends It
The Impertech Sanitation Bib is the piece that keeps outdoor educators comfortable when the day moves to the ground. Paired with the Impertech Rain Jacket, it is a complete, affordable rain kit for a whole staff.
We especially like that it lets the grown-ups kneel in the mud with the kids instead of watching from the path, which means more time outside for everyone.

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.
— RANDOLPH SCHOOL
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

At The Thistle and Root, I always recommend ODSS gear for anyone who believes that children grow best through nature—so dress for it.

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!
