Take lightweight insulation into changeable conditions with the men's Helly Hansen Sirdal Insulator Jacket, a versatile outdoor layer designed to deliver an impressive warmth-to-weight ratio without restricting movement. Recycled ECOLoft™ Air SR insulation provides efficient warmth while avoiding the tendency of traditional down to clump when wet, helping maintain more consistent performance when conditions become damp. The 30D nylon ripstop outer is lightweight yet resilient enough for regular adventures, while a PFC-free Durable Water Repellency treatment provides useful protection against light moisture. Clean elasticated finishes around the hood and sleeve ends help retain warmth and keep the silhouette streamlined, complemented by a reliable YKK® front zip. Two front hand pockets provide convenient everyday storage, while a pair of internal dump pockets offer useful space for gloves, hats or other trail essentials. The relaxed fit leaves room for natural movement and straightforward layering as temperatures fluctuate. Finished with a printed HH® logo, recycled insulation and bluesign® certification, it's an adaptable choice for hiking, travelling and active days when you want effective warmth without the bulk of heavier outerwear.
