These 750FP down jackets are designed to be worn under a shell-layer during alpine activities like freeskiing, mountaineering or climbing, but thanks to the new fabric technology, you can use it as a stand-alone jacket, even in wet weather.
The new ‘I-tube’ technology, developed in Japan, means that the fabric itself is interlaced into double-walled compartments — no stitching is needed. It also allows for the use of stretch fibres in the fabric. This is technical performance never before experienced from a down garment.
Effects of this new technology are reduced cold spots, improved weather-resistance, increased breathability and enhanced durability. But above all, these jackets are extremely comfortable — you will not believe how stretchable they are.
