Driven by innovation, ARC'TERYX was founded to build better gear. They didn’t just focus on incremental advancements, but on radically improving the status quo. They began with climbing harnesses and then proceeded to tackle packs and apparel with the same single-minded obsession for creating the lightest, best performing, and highest quality products available. To realize their vision they’ve created groundbreaking new construction technology, developed paradigm-shifting designs and harnessed major fabric technology developments. The plush Delta SV is our warmest and most breathable mid-layer fleece jacket, featuring expedition critical warmth-to-weight characteristics and outstanding compressibility. Highly breathable with excellent moisture management properties, this jacket has gender-specific anatomical shaping to reduce bulk and improve comfort with multiple layers.
