How warm are your down products?

It’s impossible to grade a down jacket (or any jacket) for a certain temperature since the surrounding conditions are always changing. The 850FP down we use for the Ultralight Down garments is extremely warm in relation to its weight — but our 800FP Red Hot Down Parka is warmer, since it contains much more down. The Ultralight Hood is slightly warmer that the Ultralight Down Jacket — only because the quilted down channels are slightly bigger. The Ultralight Down jackets are made to be worn under a shell in cold winter temperatures and will keep you warm in sub -15°C temperatures if used that way. If used without a shell we would say that -5°C is a lower comfort temperature. The Red Hot Down Parka will manage well below sub -20°C temperatures if used on top of a base-mid-shell layering system.
