Seiren suggests non-urethane stretch material "AQUATWIST^TM" and light accumulating thermal material "NANORANGE^TM" for 2009 autumn/winter sports materials.

"NANORANGE" can increase the temperature inside a garment by 3°C compared to untreated fabrics with an incorporated nano-level special heat-accumulating agent which has two characteristic functions; to absorb light, convert it into heat and store it and to emit far-infrared rays. It can maintain the performance after 30 washings.

Heat-retaining property of NANORANGE

"AQUATWIST" has the same level of stretch properties as conventional polyurethane blended stretch material through effective arrangement of stretch yarn with a special structure inside the fabric structure. It has water-absorbing and quick-dry properties owing to its special woven structure, and due to no use of polyurethane, it is light and does not degrade even after prolonged use.
