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.
Product Description
The Helly Hansen Moss Teen Waterproof Rain Jacket is our pick for older kids and teens who need dependable rain protection for full days outside. With HELOX+® technology, waterproof welded seams, and Helly Hansen's highest waterproof and windproof ratings, it's made for rainy outdoor school days, wet trails, camping trips, and everyday adventures that don't stop when the rain settles in.
The Moss keeps things intentionally simple: serious weather protection without built-in insulation. That makes it easy to layer according to the season—wear it over lighter clothing on mild rainy days or add fleece and insulating layers underneath when temperatures drop.
Why Parents Love It
- Made for all-day rain: Helly Hansen gives the Moss its highest 6/6 waterproofness rating for dependable wet-weather protection.
- Highly windproof: A 6/6 windproof rating adds protection during windy, rainy outdoor days.
- Waterproof welded seams: Welded construction helps maintain waterproof protection where fabric panels meet.
- Double storm flap: Added coverage over the front zipper helps protect against driving rain.
- Easy to layer: Minimal insulation lets teens adjust what they wear underneath as temperatures and activities change.
- Adjustable coverage: Adjustable cuffs and bottom hem help fine-tune the fit during long days outside.
Built for Real Outdoor Use
This is the rain jacket we reach for when a quick shower isn't the whole story. Moss is designed for the kind of rainy days when teens still have outdoor school, trails still need exploring, camp still goes on, and being outside means spending hours in real wet weather.
Its shell-focused construction also makes it especially versatile. Layer it over everyday clothes during warmer rain, add a fleece when temperatures cool, or build it into a more complete layering system for cold, wet days. It's practical rain protection designed to stay useful across changing seasons and outdoor routines.
Things to Know
- Rain shell, not a winter jacket: Helly Hansen rates Moss 1/6 for insulation, so warmth should come from the layers worn underneath.
- Maximum waterproof rating: Moss receives Helly Hansen's 6/6 waterproofness rating.
- Maximum windproof rating: It also receives Helly Hansen's 6/6 windproofness rating.
- Designed for extended wet weather: HELOX+®, waterproof welded seams, and a double storm flap make weather protection the focus of this jacket.
- Flexible fit: Adjustable cuffs and hem help customize coverage, while the hood can be detached when it isn't needed.
- Repair kit included: Helly Hansen includes a repair kit for maintaining the jacket through real outdoor use.

Why ODSS Recommends It
ODSS recommends the Helly Hansen Moss as an all-day rain jacket for teens who spend meaningful time outside in wet weather. Its HELOX+® construction, waterproof welded seams, double storm flap, and maximum Helly Hansen waterproof and windproof ratings make it a strong choice for outdoor school, camping, hiking, travel, and everyday rainy adventures.
We especially like the Moss for teens because it provides serious rain protection without locking them into built-in warmth. They can change the layers underneath according to the temperature and activity, making this one rain shell that can stay in the outdoor rotation through changing seasons and plenty of rainy days.
