Currently all JOG Sportswear custom-made hockey jerseys are available in two types of high-quality polyester knit; JOG Dura-Light and Jog VaporICE. These advanced materials are both constructed for maximum durability and breathability. JOG Dura-Light is the popular choice amongst our hockey customers. The inner surface has extra-fine twill that is not only comfortable but also allows for maximum breathability and durability. JOG VaporICE, which uses HRT (Heat Removal Technology), is a combination of two polyester micro-fibers along with that very important cooling layer on the inside. It is lightweight and dries extremely fast thus keeping your body dry and comfortable for a long period of time. All jerseys have a breathable mesh panel on the back and under both arms to help keep you cool and dry.
