A lightweight, thermal base-layer designed to be worn next to the skin and ideal worn on cooler days when you need to be seen. The half-zip features a new iridescent reflective stirps and a 360º reflective print. The fabric is a super soft polyester with a peached finish in modern marl look. Independent lab and wearer trials have provided very good wicking and evaporation results. The front zip allows flexibility for venting once you have warmed up on your run. This style additionally has a cosy high collar and thumb loops.
