really average

Zero breathability

At the price point I didn’t expect much but I expected more than this. This jacket is like being wrapped in plastic wrap. It’s terrible.

Excellent fit and perfect weight!

This jacket is an excellent fit for a curvy/athletic build body type. I love the shape that is much better than the similar priced jackets I had tried on that were boxy. Sleeve length is excellent. It is the exact jacket I need for 3 season backpacking.


The quality of fabric is awesome

Light but warm and stylish. My wife loves it!

Loved the down jacket

This jacket is so warm and easy to carry. Generally winter jackets are huge and occupy a lot of space, but this jacket when folded can be carried even in your purse, loved it

It’s red not pink!

I just received this and it’s not pink it’s red. So that was really disappointing. If I lived closer to the store I could return it and try to find a different jacket.

great for summer/spring/autum not winter

Great Jacket

Absolutely love this! I've a couple of similar jackets without hoods, so decided I would like one with a hood. This one was much cheaper than my others but the quality is every bit as good. Only thing that's not accurate is the picture of the colour. It's much more red than it appears on here, but I actually prefer it!

Thermal insulation - warmth

This padded jacket, worn as a 3rd layer, has been certified for a comfort temperature of -5° during a standardised test in a thermal chamber.The mannequin wears a synthetic long-sleeved t-shirt and a light fleece underneath. It works with a simulated 5 km/h wind.In our heat comparison tool, it represents 2 stars.We have also tested this model in "static" mode; its temperature rating is +5°C in this case.

*what does the rds certification mean?

We use RDS certified down: Responsible Down Standard.Thanks to our traceability system, we can guarantee the origin of the feathers in accordance with our commitment to use responsible materials. Our suppliers are committed to using only feathers that come from ducks that are bred for their meat and which are plucked after slaughtering.

Inflating power of down/feather filling

For this down jacket with its 85/15 filling, the fill power is guaranteed to be 800 CUIN or more (European standard). The fill power is a measure of the down's thermal insulation capacity and its potential to "trap" air. So, down with a higher fill power (higher CUIN number) will occupy more space, trap more air and provide greater thermal insulation.

The advantages of a duck down and feather filling

The durability and fill power properties of down give this jacket 3 qualities for hiking:- Thermal insulation thanks to the air trapped in the down and feathers- Ultra low weight: down is lighter than synthetic wadding while offering the same degree of warmth. This saves even more weight in your backpack- Ultra-compressible

In case of rain

The material of the quilted jacket is water repellent. The treatment is applied to the main fabric that makes drops of water run off the surface, thereby delaying the time it takes for water to get inside the down jacket, so you have enough time to get out of the rain.We nevertheless recommend wearing a waterproof jacket over the quilted jacket in the event of prolonged exposure to the rain.

How to wash your feather down jacket

Here are a few tips: close all the zips on your down jacket and put it in the washing machine (synthetic cycle at 30°C).In order to preserve the fill power and warmth, you can even put 2 tennis balls in the machineBe careful to set a gentle spin cycle: a fast spin cycle may create balls of feathers that are difficult to break up.For more advice, click the link below!

How to dry my down jacket

When you take your down jacket out of the washing machine it will seem as if the down has goneTHE TUMBLE DRYER is the best way to restore the fill power of the feathersPut your down jacket in the tumble dryer with 2 tennis ballsRun 2-3 drying cyclesIf you do not have a tumble dryer you can completely dry your down jacket on a drying rack by turning it over and tapping regularly

How do i reactivate the waterproofing properties?

Over time, after washing and the wear and tear during use, the water repellent treatment becomes less effective.This is how to re-activate the water repellent feature of your down jacket! use the care product: Wash-in product for reactivating the water repellent properties
