When the trail calls, you reach for something that moves with you. These active tops — soft merino t-shirts and base layers — keep you comfortable from the first mile to the last. Explore our women's active tops alongside the full range of merino sportswear, and layer up with thermal trousers for complete outdoor kit.
Q: What makes the Active Ultralite and Active Mesh collection different from other Merino wool products?
A: The Active Ultralite and Active Mesh collection are designed with a blend of Merino wool and performance fabrics for ultra-lightweight, breathable apparel. Ultralite combines Merino’s natural temperature regulation and odor resistance with a featherlight feel, while Active Mesh adds even more airflow through an open-knit design making both perfect for intense activities like running, training, or cycling.
Q: Does the Active Mesh and Active Ultralite collection offer the same odor resistance as regular Merino wool?
A: Yes! Merino wool naturally resists odors, and both the Active Mesh and the Ultralite collection retains this feature. Even after intense use, the fabric minimizes odor buildup, helping you stay fresh throughout your workout or adventure.
Q: How should I wear the Active Ultralite and Active Mesh gear?
A: Our Active Ultralite and Active Mesh pieces can be worn alone on a super hot day to keep you cool and dry. Or, their ultra-lightweight design makes them perfect for layering under another layer or over a standard base layer, ensuring temperature regulation and breathability during activity without adding bulk.
