This jacket is designed for cold, wet conditions. Usually this would make it a heavyweight, but the new breathable CLIMAPRO™ fabric has been optimised for speed and easy packing, weighing in at just 260g. The fit is slim and the hems are adjustable to reduce any flapping. Reflective logos on the front ensures you remain highly visible at night and there's a nifty watch window in the sleeve that lets you easily view your heart rate and times.

When it comes to fast winter running, the usual choice is underdress and run flat out or overdress and sweat like it's high summer. Sugoi's solution is to put full windproof fabric on the chest and upper arms of this jacket to deflect the wind while leaving the back and underarms with a thinner thermal layer to dump unwanted heat and moisture. The tight fit and super-stretchy fabric keeps warm air close to your skin and lets you run free.

There are other running jackets with removable sleeves, but this one ups the ante by allowing you to literally rip them off and turn it into a gilet mid-run. The neon panels and reflective piping make this a highly visible jacket despite the black colour. The fabric is wind resistant and breathable for top marks when it comes to versatility.

BEST IN TEST
The WINDSTOPPER® active shell and amazingly snug fit of this jacket make running in an icy headwind a cinch. And you can pump your arms without constricting your lungs because the elbows have been shaped to match your movement. It packs down small for a jacket and the mesh lining is super-smooth, making wearing it without a base layer a real option. The high collar keeps your neck warm and reflective piping ensures you'll be seen at night.
