The choice of a polar fleece comes down to 2 criteria: the intensity of your effort and the outside temperature.
1. The Intensity Of Your Exercise
During intense exercise, you sweat more. It's important to choose a breathable fleece so you don't have to wear damp clothing. The breathability of a fabric is its ability to wick away moisture produced by perspiration.
As well as being made of a breathable material, your polar fleece may be fitted with zips so you can control the ventilation depending on your level of exercise: half chest zip, full zip, side zips under armpits etc.
During a less intense effort, we warm up slower and sweat less. Breathability is therefore a less important criterion. We will therefore choose a polar fleece with a good supply of heat.
2. The Outside Temperature
The second criterion to take into account is the outside temperature. Depending on the weather, you will need the polar fleece to be colder or hotter.
For Chilly Or Cold Weather (Above 7°C)
You can opt for a micro-polar fleece: a very fine polar fleece which has the advantage of being lighter and more compact.
For Very Cold Weather (Below 7°C)
We recommend a polar fleece in a brushed fabric (in other words, with large loops or long fibres on the inside or outside as you can see in the video below).
This type of fabric helps capture more air, which is the best insulator, providing better protection from the cold.
Good to know: Some of our polar fleeces are woven with elastane thread, which gives them greater elasticity so you can enjoy greater freedom of movement. You can identify these garments by looking for the "Freedom of movement" descriptor, listed under product benefits
