What Our Gearhead® Experts Are Saying: “The Halfdays Aston nails the fashion-meets-function brief. It’s warm with PrimaLoft®, vents quickly when the sun pops, and the cinch belt gives a tailored silhouette without restricting movement.”We like the Halfdays Aston Jacket because it keeps the vibe elevated from chairlift to après without compromising performance. Recycled polyester stands up to snowy laps and parking-lot shuffles, PrimaLoft Black Eco insulation keeps the core cozy without bulk, and the helmet-compatible hood, pass pocket, and underarm vents make everyday resort details feel dialed. The adjustable belt snatches the waist for a polished look you can take straight to town.
