Use the chart below to determine your size. If you’re between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit. If your measurements for chest and waist correspond to two different sizes, order the size indicated by your chest measurement for tops and your hip measurement for pants.
Our three different fits - slim, regular, and relaxed - ensure that when worn together, layers move and breathe like a single garment.
A snug, close-to-body fit for low bulk layering.
Neither snug nor loose - garments that are worn solo or over other layers.
Loose fitting lightweight layers.
When you start a morning run on a summer day, you might zip the Women's Spark Short Sleeve Half Zip up, as a block from the initial chill, but as you, and the day heat up, the exclusive Cool-Lite™ fabric will keep you cooler and breathe better than cotton, or wool, or even Polyester. Eyelet mesh venting panels help let sweat evaporate in key areas, and if you need to really let the heat out, that half zip provides instant venting.
