The Sonic LS Zip is versatile and lightweight ideal for mountain running and fast hiking. Designed with a relaxed fit, raglan sleeves and an odour control treatment to finish off. Fabric-wise, it's created using Motiv Aero fabric, making it fast-drying, quick-wicking and highly breathable. With its technical material, it wicks moisture away from the skin keeping you dry whether you are running, cycling or taking on a tough ascent. It also has a high collar for when you need your neck warm, thumb loops and orange and blue half zip for rapid cooling.Fit: RegularWeight: 130g/4.6ozMotiv Aero single jersey fabric with subtle mesh structure (85gsm) with odour control treatmentMicroactive low bulk seams, for strength and comfort next to skinCollar and deep venting lightweight YKK chest zipRaglan sleeve constructionHidden stretch thumb loops100% polyesterCentre back length (Size M): 70cm / 27.6inchColour: Dark grey, orange & blue
