Osteri - Kids' ReimaTec Seawool® Winter Jacket
Color: Aquatic Blue
All Reima products run about one size larger than traditional US sizes so ordering your child’s current size is like ordering a size up.
Product description
The story of this award-winning winter jacket is of marine origin: Discarded oyster shells add warmth to the fabric, and the super warm insulation is made from recycled ocean-bound plastic.
Crafted with waterproof, windproof, and breathable material, this jacket efficiently repels water and dirt, helping your kid stay clean and dry.
Osteri jacket is the winner of both ISPO Award 2023 and Scandinavian Outdoor Award (SOA) for its superior performance.
The waterproof fabric is excellent for very wet surroundings: active play and outdoor life in heavy rain or wet snow
Water column over 10 000 mm
Seams are not taped. Please note that the seams of this product are not sealed, so the product is not completely waterproof.
Very warm insulation. Good for outdoor winter activities in the coldest environments.
Temperatures ca. -10 - -30 °C (20 to -20 °F)
Excellent breathability. Best moisture management for active play and sports.

Best winter jacket
In recent years, I have bought the most expensive and best jackets for my son from many well-known brands. But with this jacket from Reima, all other jackets can pack up and go home.

Bought three jackets for my kids. Very warm, light and comfortable. Plus very easy to remove any dirt without washing the whole jacket.

Warm <3
It is really warm and also breathes well. A lovely garment for brisk, cold weather, where you don't necessarily have to wear so many layers underneath! The adult size is a bit snug around the chest and hips, but it can still be worn and allows for movement! The somewhat longer hem also better protects the backside.

Warm jacket, but it doesn't withstand wear.
After a week of use, there are several holes in the jacket. Reima's clothes have usually withstood wear much better.

Warm and lovely jacket
I bought one first for my little brother, and it is warm and light for a waterproof winter jacket, so now I'm buying one for my big sister too.

Warm jacket
A wonderfully warm fluffy jacket. My frozen child hasn't complained once despite us being up in -20 degrees. A bit larger than normal size. The only downside is too few reflectors.

very disappointed
Very disappointed with Reima. The jacket I received had a broken zipper and a torn tag. It was obvious that it had been a returned product and no one checked to make sure it was not being put back on the flow because it was defective. I had to return it at my own expense.

huge hood
a huge hood that looked like a parachute. It was snowing heavily, and sleeves were wet.

My Daughter is very happy with this coat, she said the coat is very warm and snuggly. she feels like being in a cocoon. the coat has plenty of room if she's wearing sweater, or wear many layers. has room to grow.

Incredible coat!
I'm only sorry we didn't discover this brand sooner! My 11 year old is obsessed with this coat, which is so well-made and warm. It's puffy without being bulky. Awesome.

Love this jacket!
This jacket is perfect for my son. My son loves it and it's toasty warm. I purchased his regular size and I anticipate it will fit him next year. We have been buying reima snow gear for a few years now because my kids can wear them for 2+ winters and they still look nice. We are very happy with this purchase.

The zipper was difficult
The zipper got stuck in several places on the jacket. He didn't want to use it since he had to get help to take it off every time, unfortunately. It's a pity because otherwise, it's a very nice jacket.

Absolutely love!! My son goes to an outdoor nature school and we live in Utah so this will be perfect. We have tried other popular brands in the past but so far this seems like it will be our new go to for outdoor wear.
