Whether it's date night on the slopes or going out to dinner, the Arcteryx Atom LT Vest can take on the challenge. Articulation provides maximum range of motion as well as comfort for all day wear. The synthetic insulation Coreloft keeps the body toasty warm even if water starts to seep through. Easily storable, the Atom is lightweight and packs down to nothing which makes it a great travel option. The Atom can resist light drizzles thanks to the DWR (Durable Water Resistant) Treatment that covers the entire vest. The No Slip Zip feature allows the zipper to be zipped up and down at certain lengths without sliding down or getting in the way.
