Description The Sonic LS Zip is an efficient, long sleeve layer, ideal for mountain running and fast hiking. Designed with a relaxed, regular fit, comfortable Raglan sleeves, and lightweight, breathable fabric, finished with an odour control treatment. Offering you a layer of protection on cooler days when a tee won’t cut it, or hotter days when covering up from the sun is key, it’s ideal for multi-day adventures. Built with ultralight Motiv™ Aero fabric, the Sonic LS Zip is fast-drying, quick-wicking and highly breathable. With its subtle mesh structure, the fabric wicks moisture away from the skin keeping you dry on those challenging climbs. It has stretch thumb loops, and a mid-height collar ideal for covering up the back of the neck, and a deep, half-zip, for dumping heat quickly when the incline steepens Fit:Regular Weight:105g/3.7oz Centre back length:(Size 10): 64cm / 25.1inch Product Code:QBL-04 Motiv™ Aero single jersey fabric with subtle mesh structure (85gsm) with odour control treatment Microactive low bulk seams, for strength and comfort next to skin Collar and deep venting lightweight YKK chest zip Raglan sleeve construction Hidden stretch thumbloops 100% polyester Centre back length (Size 10): 64cm / 25.1inch
