Many styles are made from merino wool (either 100% merino or merino blended with nylon and spandex). Others use a lightweight double-knit blend of recycled polyester, rayon, and spandex.
The selection includes midweight interlock knits, micro/extra-lightweight jersey knits, and lightweight double-knit fabrics.
Most pieces feature a mock turtleneck; a few options include a hood. Zipper styles range from a front 1/4-zip to some half- or longer-zip fronts depending on the item.
They’re designed for multi-season use: midweight pieces are recommended for spring, fall, and winter, while micro-weight items cover spring through winter. Common activities listed include everyday wear plus hiking, camping, biking, running, fishing, hunting, and snowsports.
UPF ratings listed include 50+ for a midweight merino option and UPF 20 for the micro-weight merino styles.
