Waterproof rain jacket for outdoor educators, with stretch PU fabric, welded seams, an attached hood and a ventilating back cape.
Product Description
The Helly Hansen Impertech Sanitation Jacket is a fully waterproof rain jacket for teachers, staff and grown-ups who spend rainy days outside with kids and need a jacket that keeps up.
Built from Helly Hansen's stretch Impertech PU fabric with MicroWeld seams, it is a simple, tough barrier layer. Wear it over the warm clothes you already own, and pair it with the matching Impertech bibs for full-body rain protection.
Why Parents Love It
- Waterproof barrier: Helly Hansen describes the Impertech fabric as fully waterproof, with MicroWeld seams for watertight construction.
- Moves with you: full stretch fabric and raglan sleeves make it easier to crouch, reach and lift.
- Snug at the wrists: elastic cuffs help keep rain from running up your sleeves.
- Double front closure: a front zip sits under a snap storm flap to block wind-driven rain.
- Hood that stays put: the attached hood has an elastic edge for a closer fit.
- Some airflow: a back cape vents the jacket.
Built for Real Outdoor Use
This is the jacket for rainy-day recess duty, forest school mornings, garden chores and puddle walks with a full class. It is workwear first, built for daily use in wet conditions rather than occasional storms.
A soft circular knit backing makes it more comfortable against your layers, and the generous cut leaves room for fleece or a warm jacket underneath on cold, wet days.
Things to Know
- Fit: generously cut in men's sizing. Helly Hansen reports that it runs large and suggests going one size down.
- 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: this is a shell. Layer warm clothing underneath on cold days.
- Pockets: Helly Hansen does not list pockets on this jacket. For more pockets and knee-length coverage, look at the Impertech Long Coat.
- Care: rinse and wipe clean when possible, and wash only when needed.

Why ODSS Recommends It
The Impertech Sanitation Jacket is our everyday rain jacket for outdoor educators: fully waterproof, easy to move in and priced so a whole staff can gear up. It is the grown-up version of the ODSS approach for kids: keep the warmth you have, and add the waterproof protection you need.
We especially like it paired with the matching Impertech bibs, so the grown-ups stay as dry as the kids and can say yes to more time outside.

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.

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!
