Temperature

It's hard to establish what temperatures our garments can stand. There are many factors which affect our insulation requirements. Besides actual ambient temperature, the two main factors are: our activity level and the wind. Very high wind speeds will always intensify the effect of low temperatures and, as everyone knows, activity has a dramatic effect on our metabolic rate, capable of raising it by 500% and more.
Higher metabolic rate means higher internal heat production. This is why we prefer not to give you a precise temperature range for our jackets, but only a general idea of how warm each type of Parajumpers coat can keep you, considering the following features that effect the jacket's performance in cold weather:

- Amount of down fill (if the fill power is the same, more down means more warmth)
- Fill power (with the same amount of down, the higher the fill power, the warmer the coat will be)
- Weight of the shell fabric (heavier fabric is usually more tightly woven and, therefore, protects you from the wind)
- Coatings (A coated fabric has even better windproofness).

Of course, within the same family of jackets, a short style without hood will keep you less warm than a longer model with a hood and fur trim. We hope this guide will help you choose the right Parajumpers jacket for your type of climate.
