Great Jacket

This jacket is very comfortable and is a fantastic layer to own. The jacket performs fairly well in the rain with the coating they have applied repelling most of the water. The jacket still keeps you warm once it is wet. Sadly some of the insulation is seeping out the seems after a few months of regular use.

Starting to come apart already.

This jacket has only had light use and the insulation is starting to come out. From reading previous reviews this seems to be a common problem. This is a shame as it's a nice warm jacket which looks and fits very well, a more resilient outer fabric is needed.

Warm lightweight jacket

vivid bright green/yellow jacket which is warm and lightweight. It packs down to a small size in its own reversible zipped pocket. At a bargain price of just under £30 what's not to love

Good .... but

I really depends what you looking for. First of all this jacket is not wind resistant.So cycling on the chilly day with just a t-shirt under will feel cold, unless you put more layers underneath. On the other hand it breathes very well. So it is somewhere in the middle. It retains body heat quite well during treking. Its also nice bit off kit to put on the Gore tex layer when belaying or resting. It feels soft to the skin. Hood is good but has no adjustments. Fit is snug . I am 185 and 85kg - size L suits me well.

Great value on a budget

I've had two versions of this jacket over the last five or so years, they are not the most compressible but they are great value for money and I pretty much use them every day in winter autumn and spring in Scotland..... This is a great jacket for putting over the top of you whilst you eat your sandwiches on a summit or just wearing on a cold windy winter walk, it soon comes off if you have to go up hill any... Probably not warm enough for a winter climbing belay jacket though in my comfort range. Only gripe is the zip goes in the end after about two seasons hence why I'm on my third incarnation.... Solid buy

So Nice Design

Loved the grey softy is warm..very light

Very low quality

This is a cheap quality jacket. I never expected such product form decathlon. I have bought many products from decathlon so had no doubt but this is very cheap. Their 1000rs jacket provide much better insulation

Not As Good As Expected

Not suitable for even 0 temp.

Hello Sir,

Thank you for writing to us and for the feedback, the jacket performs at -5 degrees when all the layers(baselayer-shirt-fleece-jacket) have been worn and the temperature mentioned is when the person is in active state, where the body is also generating some amount of heat.

If you are not satisfied with the product, please visit any of the stores and exchange the product of your choice.

Please let me know if you have any queries


Not warm

Not worth to buy

The color is good and stands out in a crowd. It is lightweight and packs easily in luggage. Its does not keep out the cold or wind when riding scooter though it keeps 80 to 90 percent warm at standstill and after few hours outside or at night the chill starts to creep in.

Not Suitable For Low Temperature Below 10°C

I purchased this jacket and found out that it keeps me warm inside the room only and when I step out of my room in cold which is 10°C and a little wind was blowing it cannot resist that also and gets wet when water gets poured so I recommend not to buy and my product is little bit defective too and I am not able to return it or replace it. I hate this jacket I am a usual costumer of decathlon but this is my worst experience.
