Fancy Zip-Neck Wool-Blend Jumper

Don't be fooled by its name: the Fancy jumper from Isabel Marant Étoile is sporty athleisure in its finest (and comfiest) form. Whipped up in a plush merino wool blend, it's topped with ribbed trims and a quarter-zip that pulls up to a sprawling high turtleneck. Detailed with a speckled weave, this snug relaxed-fitting knit is one of those layers you'll want to throw on whether you're running errands about town or spending the day horizontally.

• 55% merino wool, 27% polyamide, 17% viscose, 1% elastane; rib 67% merino wool, 19% polyamide, 14% viscose

Launched in 1999, Isabel Marant's Étoile line is all about youthful collections that blend relaxed tailoring with bohemian detailing and a Parisian attitude.
