The hydrophobic tech of the Atom series offers midlayer insulation and water-resistant tech in a lightweight package with high stretch. Athletic Fit: • Anatomical mapping and gussets reduce excess fabric for greater mobility. • Allows room for an additional baselayer. SL: Super Light uses ultralightweight materials improving packing and wear while reducing bulk. Tyono 20 fabric: • Lightweight nylon taffeta offers durable resilient performance. • Mechanical stretch for improved mobility. • DWR (durable water-repellent) finish. Torrent fleece side panels: • High degree of resilient stretch improves mobility with minimal loss of elasticity. • Polygiene silver-salt finish helps reduce odor accumulation. • Moisture-wicking performance distributes energy-sapping perspiration across the surface to dry quickly. Coreloft Compact Insulation: • Compact performance offers light insulation with low bulk. • Compressible multidenier polyfill is siliconized for a hydrophobic finish. • 40 g/m2 weight. Highly compressible design packs away for easy stowing. StormHood: • Uninsulated design maintains a low profile. • Water-resistant laminated brim. • Drawcord secures fit without reducing visibility. Full zip with inner draft flap. No Slip Zip prevents the main zip from opening on its own. Zip hand pockets set above pack straps. Contoured cuffs with stretch fleece panels. Droptail hem with drawcord. Shell: 100% nylon Insulation: 100% polyester Lining: 100% nylon. Machine wash and tumble dry. Imported.
