OMM Sonic Jacket 

Women’s windproof jacket review

50g (women’s S)
Jackets don’t come much lighter than the Sonic, made from featherweight ripstop nylon Point Zero fabric that adds a highly effective layer of protection. The cut is slim with a drop tail, there’s an adjustable hem, you get reflective details and the cuffs and thumb loops are lined and comfy. The whole thing rolls away into its collar too.
Verdict: Super-light, comfy, protective layer with a tiny pack size.
