The choice of a polar fleece comes down to 2 criteria: the intensity of your effort and the outside temperature.
For Chilly Or Cold Weather (Above 7°C)
For Very Cold Weather (Below 7°C)
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
