Building off the legendary versatility of the Atom LT Hooded Jacket, the Arc'teryx Men's Atom SL Hooded Insulated Jacket retains the LT's multi-use functionality, all while shaving 20-grams of Coreloft insulation to achieve a lightweight layering piece that's ideal for summer adventures. In fact, you'll find the Atom SL Hooded Insulated Jacket saves approximately 3. 5-ounces over the LT, making it better suited for lightweight alpine hikes and minimalist peak-bagging missions in the summertime. Coreloft Compact 40 synthetic insulation retains body heat on those chilly summer mornings and evenings. This insulation is highly compressible, lending itself to easy storage within your pack. Leveraging Arc'teryx's Tyono 20 shell fabric, the Atom SL Hooded Insulated Jacket remains lightweight and surprisingly durable. The shell's DWR treatment repels outside moisture from passing showers, ensuring you stay nice and dry through all but torrential downpours. Boosting air permeability where you perspire most, Torrent fleece side panels substantially increase ventilation and overall flexibility during high-octane pursuits. Additionally, mesh lining along the sleeves boosts next-to-skin comfort. Refined over previous offerings, the No Slip Zip enhances core ventilation without inadvertently opening during rigorous activity. It works like a series of speed bumps, preventing self-opening when it's partially unzipped. Other design-savvy features include two zippered hand pockets, an adjustable, low-profile Storm Hood, and shaped cuffs with stretch fleece. There's also an adjustable hem cord for sealing out chilly drafts and blustery conditions.
