Flattering - Tight on the Chest

So nicely lightweight and flattering. However, if you are not flat chested, your "regular size" (mine is medium) will be way too tight.

Light weight and warm

This light-weight gilet is perfect for wearing under and outer layer to give extra warmth. It is wind proof and not at all bulky I find that it also packs away quite small if I get too warm when walking.

Very effective product!

I really suffer with the cold and in the colder months I constantly struggle to get warm. Wearing this gilet over a couple of layers I can instantly feel the heated trapped next to my body and I feel super toasty! The best thing about this product in the draw sting around the bottom. I usually find with gilets the cold air comes in from underneath but the drawstring stops this and with the high neck I really can't rate this product enough.

Great gilet

Great gilet, really comfy and lightweight.

Love this, so versatile, warm, flattering, HUGE pockets and easy to stuff in my bag /pack away. An essential!

Good lightweight gilet

Bought as an extra layer for my better half, who is delighted with it. Warm, but not cumbersome and fits well.

I used the size chart on here and ordered accordingly, I'm a 16)18 I ordered a 2xl fits perfect, nice length

Nice but too tight across the chest

This is a really nice gilet but unfortunately for me it is way too tight on the chest. I'm 5'6 with a 36C bust and am a UK size 10-12 and bought the medium. The large is too big everywhere else but fits on the chest. I've noticed a lot of Decathlon tops this year are really tight across the chest and I don't even have a particularly large chest. Decathlon please could you bear in mind some women have larger chests and smaller hips when designing clothes? A lot of women are slim with larger chests. Not every woman has a pear shape. Had to return.


Lovely garment, very good value.

Lehká, teplá, příjemná. Bylo by fajn, kdyby byla u stahovací gumičky ve spodní části možnost gumičku upevnit, aby netrčela dolů.

Péřová vesta

Vestu jsem kupovala jako tepelnou vrstvu pod bundu. Tento účel splnila. I při větší námaze se ve vestě dobře pohybuje a je v ní příjemně.

*what is rds certification?

RDS-certified ethical 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 commit to using only feathers from ducks raised for their meat and slaughtered before down and feathers are collected.

Filling power of down/feather stuffing

For this down vest with its 85% down/15% feathers 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.

What are 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-lightweight: Down is lighter than synthetic padding 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 down jacket is water-repellent. It lets drops of water roll off the fabric, delaying water from getting in the jacket and giving you time to find shelter. We nevertheless recommend wearing a waterproof jacket over the down jacket in the event of prolonged exposure to the rain.

How do i wash my feather down jacket?

A few tips: Close all the zippers on the down jacket and use a synthetics washer-dryer cycle at 86°F. To maintain the filling and warmth, it's even better to add 2 tennis balls in the machine Be sure to use a gentle spin cycle: Too strong a spin may create feather balls that are difficult to undo. For more tips, click on the link below!

How do i dry my down jacket?

When you take your down jacket out of the washer-dryer you will think that the down has disappeared. The WASHER-DRYER is the best way to reinflate the feathers. Put your down jacket in the washer-dryer with 2 tennis balls. Set it for 2-3 drying cycles. If you don’t have a tumble dryer, you can always dry your down jacket on a clothes horse and keep regularly tapping it.

How to restore water-repellent properties?

The water-repellent treatment becomes less effective with time, washing, and use. Here is how to restore the water-repellent properties of your down jacket! You can also use the care product: Treatment restoring water-repellent properties

A score for comparing the products' environmental impact

The environmental impact of the product is calculated over its entire lifecycle using different indicators. An overall ABCDE score is given to help you easily identify products with the best environmental performance by comparing products of the same type (T-shirts, pants, backpacks, etc.). Decathlon actively promotes this environmental rating initiative. For further information:

Product testing

All our down vests are laboratory tested in 3 mph winds and worn as a 2nd layer on a thermal model (over a long sleeve T-shirt). Their level of thermal insulation is measured on a scale of 1 to 5, so that you can make the choice that best suits your use. Worn underneath the TREK 100 down jacket, it can provide 11°F extra warmth when compared to a down jacket worn without the vest. Choose the best suited to your activity.
