What Our Gearhead® Experts Are Saying: "I like how the Sarin takes insulation and dials it into something minimal. It keeps me warm on chill days without all the bulk, and the hoodless silhouette layers easy under a shell or over a hoodie."Requested by the Armada team and built to perform, the Sarin 2L Insulated Jacket is an insulated outer layer with a clean, modern aesthetic. Its boxy fit and hoodless design cut a fresh silhouette, while stealth tech elements like water-repellent fabric and lightweight recycled insulation quietly do the heavy lifting when temps drop. Crafted from bluesign® approved nylon with a 10K/10K waterproof/breathable rating, the Sarin offers solid protection against winter's daily grind. It’s lined with 60g of recycled polyester insulation in the body and 40g in the sleeves for balanced warmth. A micromesh chin guard, glove-compatible cuffs, and a media pocket complete a feature set that’s practical without overcomplicating the look or function.
