The Gielas shirt is made from 100% nylon offering a lightweight comfortable shirt when worn next-to-skin or over a thermal base layer. A ventilated back yoke allows effective temperature regulation and retention straps in the upper arm allow sleeves to be held securely when rolled up. The Gielas benefits from two zipped storage pockets with a hidden retractable tool attachment for nippers and other fishing tools. The shirt also enjoys articulated sleeves for ease of casting movement.
