A BETTER ARMLING
With INEOS Genadiers, we set out to develop a better seamless armling. Others on the market are made with a nylon/Lycra® blend that tends to retain moisture. But we realized we could achieve better moisture management with a polyester yarn. However, working with polyester makes it more difficult to achieve the right elasticity, shape retention and manufacturing consistency. It took a year longer than we thought, but we're all glad we stuck with it. These arm warmers are a favorite of the pros because they are incredibly lightweight while being extremely warm for their weight. But even in milder conditions, you won't overheat. They are so elastic that you can barely feel them. But when you take them off, they take up a fraction of the space that normal arm warmers would take up in your pocket.
