Rab Down Jacket Warmth Guide - Ultralight Outdoor Gear

Generally the more down in a jacket (fill weight), the warmer it is going to be but this assumes the down is the same quality. However, down quality can vary significantly and is measured by its fill power. A higher fill power down will keep you warmer than a lower fill power. To make matters worse there are two widely recognised methods of measuring Fill Power - the 'US' Method and the 'EU' Method. Rab use the US method to calculate their fill power. Both methods work on the same methodology but the 'US' Method gives a slightly higher figure than the 'EU' method for the same quality down - so an 800+ Fill Power (EU Method) is approximately equivalent to an 850+ Fill Power (US Method).
