OMM Sonic Women's Jacket The perfect super lightweight and extremely breathable windshirt, now with an even lighter construction. Made from PointZero fabric, this Sonic Jacket from OMM is windproof and features a DWR treatment to ensure water resistance and improve its weather protection and stain resistance. The jacket has a low pack size and folds up easily into its own collar for easy and convenient storage when it is not needed. A full-length zip allows you to control ventilation and a drawcord hem allows you to customise the fit and keep wind chill out of the jacket. The fit is women-specific for a flattering shape and the drop hem offers improved coverage as you go. Minimal stitching ensures comfortable wear and reduces the risk of irritation from rubbing and chafing.
