The Grundens Solstrale Lightweight Sun Shirt is a long-sleeved T-shirt made from 100% polyester (140 g/m²). Its "active fit" cut has been designed to allow great freedom of movement, particularly in the arms and shoulders, so that you can make one throw after another without any discomfort. The HeiQ anti-stain and anti-odour treatment of this T-Shirt is another major asset for sport fishing.
