The open knit of Capilene 2 V-Neck (4-oz polyester that’s 54% recycled) delivers maximum breathability, superior wicking and the fastest dry time of all Patagonia's Capilene fabrics. Worn on its own, it keeps you dry and cool during high-exertion activities in warm conditions. Worn under a shell when a chill wind blows, it wicks perspiration and helps to insulate. The top’s self-fabric neckline is feminine and feels soft; highly breathable flat-rib panels under the arms and on the sides eliminate chafing. Raglan sleeves increase range of motion and comfort beneath pack straps. With Gladiodor® natural odor control. Recyclable through the Common Threads Recycling Program.
