Check the size first

I now own two of these. WARMEST fleece ever! I love them. I bought two because the first was a bit snug. The XL I bought was a bit snug. The XXL fits way better. They do suggest you check the size chart (which I didn't).


I like the quality

Best Top Ever

I absolutely LOVE this fleece. I wear it every day. I can’t believe I paid less than £30 for it. Thank you Decathlon!

Sizes are smaller

I ordered an XL and it is more like an L size.

Way small. get your sizing right

Far too small for a medium. Your sizing is so inconsistent. Also, delivery is expensive and exchange / return is a pain. I like your stuff but I won't be shopping online again.

Fits very small and isn't as warm as advertised.

Advertised as "ultra warm", which simply isn't true (and I run warm). It's definitely warm, but too thin to ever be considered ultra warm. It also fits very small. I am normally a small in most hoodies (5'10" and 11 stone), but always size up to a medium at Decathlon as their garments are designed for more athletic figures, but this is tiny. The arms and torso aren't long enough, and I can barely pull the hood up it's so small. So I'd need a large, which will likely be too bulky. The material seems to be of good quality, and it looks ok, not as good as in the photos, but just ok. I'll be returning it.

Fantastic jacket

Love the Fleece jacket

Love the Fleece jacket, very warm especially in this cold weather & not only that it has a hood, which you can use or not. Excellent value for the money spent! Would definitely recommend this product to anyone buying it! Excellent service too!!

Fleece hoodie

Very good top for the money, not thin material like some others but a nice and warm mid layer for this weather or outer layer for summer

Warm, slim-fitting fleece.

It's a very nicely made, warm fleece, but it's very slim-fitting. I'm 5ft9' 11.5 stone, 40 chest and 32 waist and I need to size up from the medium I ordered. It'll be the only item of clothing in large that I own. The medium was long enough in the body and arms, just tight across the chest.

Love the colour

This was brought as a present for a friend who loves the colour blue, unfortunately the size I choose is a bit small, so hence the return of the product, hopefully I can still get this in a bigger size, fingers crossed .


Really good quality

How can i be sure that my fleece is warm enough for hiking in the winter?

The inside of your fleece is brushed, a process known to preserve heat. The principle is simple: the component weave is structured to add volume to trap air, naturally insulating. It is exactly the same principle as animal fur or feathers. A little extra - this jacket is equipped with cuffs at the bottom of the sleeves limiting the entry of cold air.

What is the fleece component and why is it so warm?

The fleece fabric, made of synthetic fibers, aims to reproduce the performance of wool: warmth and thermal insulation, while being lighter. It’s soft, comfortable, dries quickly and lets the skin breathe.

Isn’t such a soft, pleasant component fragile?

To check the durability of our products, we carry out tests on the components. We check, for example, that the fleece doesn’t pill, the colors don’t run, and that repeated washing doesn’t change the properties of the fabric. The abrasion-resistance of a fabric is measured by a test called the Martindale test. This machine rubs a sample of the fabric on a reference surface with a weight at its end.

A comfortable, practical snow hiking fleece

With its loose fit and lightweight component, your fleece provides freedom of movement, essential for hiking on snow. The zipped pockets keep everything that needs to be at hand safe (tissues, lip salve, gloves, keys...). The warm hood makes your fleece jacket an ultra-warm garment that’s ideal for hiking in very cold weather.

How to dress properly for snow hiking?

To dress properly in winter, whatever your activity, we recommend using the 3-layer principle: layer 1: The high-tech base layer transfers moisture away from the body to keep your skin dry. layer 2: The second layer (fleece, sweater) provides warmth and transfers moisture outward. layer 3: The jacket protects you from outdoor conditions: rain, snow, wind. The whole outfit must be breathable in order to eliminate moisture.

How does my product warranty work?

This product is guaranteed for 2 years from the date shown on the sales receipt. A product covered by the warranty will be exchanged free of charge. The warranty covers product defects, excluding those resulting from normal wear and tear and improper use.

What is the environmental impact of a product and how can i compare it?

The product's environmental impact is calculated over its entire lifecycle using different indicators. A score from A to E is given to help you easily identify the most eco-friendly products by comparing products of the same type. Decathlon is committed to this approach.

Product testing

We perform 2 types of thermal tests: - a test of the material of our fleeces. - a thermal mannequin test in a thermal chamber. Here, we reproduce the conditions of temperature, wind (3 mph) and humidity that you will encounter in the mountains when walking at 3 mph. These tests are used to validate our design choices and adapt the thermal insulation where you need it most.

Storage instructions

Store in a dry place away from the light. We recommend you avoid chemicals, such as bleach, which could damage the thermal insulation of your clothing.
