This new IXS Flex-ST jacket is especially flexible in fit due to the new Size-Adjust-System! 2 circumferential zippers from the jacket waistband at the front over the shoulders to the jacket waistband at the back allow a significant increase in width. Now even a thick quilted jacket for the cold days fits under the jacket! So the jacket still fits perfectly even if the thermal lining is removed on hot days. It is flexible for personal weight fluctuations or reduces the jacket width by closing the zipper.
