The fleece jacket has been an essential product in the world of outdoor activities and more broadly in the world of clothing since its rise to popularity. The many qualities of this fabric are perfectly suited to sporting use as well as casual everyday wear. The fibre of a fleece jacket is warm, comfortable and very soft. It also doesn't irritate the skin, dries quickly and is long-lasting. This lightweight and extremely breathable fibre has ultimately become a must in any suitcase or wardrobe. To help you choose the right fleece jacket model for you, here is a comprehensive guide with all our advice on this product and its different versions depending on your needs.
What is a fleece jacket?
Fleece fibres are used in garments of the same name (fleece jackets, which can have short or long pile), but also in softshell jackets. You can also find fleece trousers, gloves and hats. Fleece is also sometimes used as a lining in certain garments. Fleece fibres are generally made from polyester, PET (polyethylene terephthalate) and other synthetic fibres (sometimes recycled).
The different types of fleece jacket
The heavyweight fleece jacket has a density of 300 g/m² and offers maximum warmth in winter conditions. It forms an effective barrier against the cold but does not wick perspiration away efficiently enough. Its significant thickness therefore limits the comfort it can offer. A thick fleece is often poorly suited to physical activities requiring a high degree of mobility and is rarely used for dynamic activities.

The finest fleece jacket has a weight of 100 g/m². This is the version chosen to slip under a windproof or another jacket. It provides slightly less warmth, but its slim profile offers much greater comfort.
It is the perfect fleece jacket for physical activity and is often chosen for winter hiking, Nordic skiing, snowshoeing and any other sport requiring solid protection against the cold while preserving good freedom of movement.
The mid-weight fleece is more breathable than the heavyweight fleece and warmer than the lightweight fleece, making it more versatile than the other two. It can be worn as an outer layer when temperatures are mildly cool, or slipped on as a mid layer in the coldest conditions. Explore all our sleeveless hiking jackets.
