Arc'teryx Atom Vest -

Okay, Goldilocks: when a full jacket is too warm and going without anything is too cold, stay just right in the Arc'teryx Women's LT Vest. Pasting yourself across rock faces in late March or early November requires more than your favorite shirt, and the Atom LT's slim silhouette cuddles your core without getting in the way of the next move. When the wind kicks up or wet storms roll through, throw a shell over the Atom LT vest for additional protection.

The vest's cozy Coreloft synthetic insulation makes sure your core doesn't freeze and it packs down small. The ripstop nylon hiding the cozy Coreloft dances the fine line of breathable and water-resistant. The DWR treatment helps water bead on the vest's surface so you can shake it away, while the polyurethane coating enhances wind resistance without diminishing breathability. At the same time, breathable Polartec Power Stretch panels let perspiration evaporate away. Hardface technology incorporated into the Polartec protects the side panels from sharp elbows, spiky branches, and jagged rock outcroppings.

A body-skimming fit slips under outer layers easily if the clouds threaten or a cold front swings through. And since the vest packs into a tiny ball and weighs a paltry seven ounces, you needn't hesitate to pack it everywhere. When you're running through the woods to Nana's house, walking to a lecture on campus, or hiking through the fall colors, the Atom LT vest will do you just right—it snuggles but doesn't suffocate, stretches but doesn't sag, and packs without being portly.
