Enjoy some moments of Zen in our Merino Movement collection. Soft, stretchy, and made to move, this slim-fit top blends Merino and TENCEL™ Lyocell fiber for cooling and odor resistance. Flatlock seams help enhance comfort, and thumbholes keep sleeves in place while you find your flow.
Merino Movement Collection
The Merino Movement collection is built for the active layer of the Smartwool system — the pieces between base layer and outer shell, the tops you actually train in. Soft, stretchy, and made to move, the collection blends Merino with TENCEL™ Lyocell fiber for cooling and odor resistance across yoga, HIIT, running, and the everyday active rotation.
Merino + TENCEL™ Lyocell Performance Blend
28% Merino Wool, 28% TENCEL™ Lyocell, 25% Recycled Nylon, 19% Elastane — an equal Merino+TENCEL split that balances next-to-skin comfort with moisture management. Merino handles the odor-resistance and temperature regulation; TENCEL™ Lyocell adds a cooling softness and moisture wicking that pure Merino can’t deliver alone. The recycled nylon backbone holds shape; the 19% elastane delivers the four-way stretch recovery yoga, running, and HIIT demand.
Four-Way Stretch Knit
The four-way stretch knit fabric moves with the body across every direction a high-output session requires — reach, twist, fold, hold. The 19% elastane content is the highest of any Smartwool apparel fabric, delivering the stretch recovery a fitted activewear top needs across the elbow, shoulder, and torso across hundreds of wear cycles.
Slim Fit For Active Wear
Our slim fit is intended to follow the contours of the body — fitted through the torso and arms without compression. The cut layers cleanly under a shell or jacket for outdoor sessions, and stays put on its own for studio work where loose tops get in the way of a stretch or a hold.
Mock Neck Coverage
The mock neck rises partway up the neck — more coverage than a crew, less commitment than a full turtleneck. The partial collar seals in warmth across the throat on cool-morning runs and studio sessions; the soft knit sits cleanly against the neck without binding or rolling.
Thumbholes At Cuffs
Thumbholes at the cuffs keep the sleeves in place during high-output movement — they don’t ride up the forearm in a downward dog, a shoulder press, or a stride push-off. The thumbholes also let you pull the cuffs over your palms for added warmth on cool-morning runs before the body warms up.
Flatlock Seams For Chafe Resistance
Flatlock seam construction designed to help increase comfort and minimize chafing. The flatlock stitch lays flat against the skin rather than raising a ridge, so the seams don’t rub against the underarm, the sports bra strap line, or the spots where the arms swing past the torso during a run.
Reflective Elements For Low-Light Visibility
Reflective elements add low-light visibility for early-morning runs, evening commutes, and the shoulder-season days when daylight runs out before the workout does. The reflection is integrated into the knit rather than printed on, so it doesn’t fade or peel across the life of the top.
Made In Cambodia
28% Merino Wool, 28% TENCEL™ Lyocell, 25% Recycled Nylon, 19% Elastane. Exclusive of Decoration and Elastic. The recycled nylon backbone supports the stretch and recovery; the Merino handles the next-to-skin performance and odor resistance that makes the top multi-day wearable across a training week.

Washing
Machine wash cold on a gentle cycle with like colors. Cold water protects the Merino and TENCEL™ Lyocell fibers; the gentle cycle keeps the flatlock seams from pulling and preserves the four-way stretch recovery. Turn the top inside out before washing to protect the outer knit and the thumbhole cuff construction.
Drying
Dry flat. The 19% elastane content can lose stretch recovery under tumble-dry heat over time; laying the top flat on a clean towel preserves the four-way stretch across hundreds of wash cycles. Keep out of direct sunlight to protect color and the reflective elements.
Bleach
Do not bleach. Bleach damages Merino wool fibers, breaks down the TENCEL™ Lyocell, and strips the color from the knit. Bleach also degrades the reflective elements.
Ironing & Decoration
Cool iron as needed. Do not iron decoration. The knit recovers from light wrinkles with steam or a cool iron; direct high heat on any printed graphics or heat-transfer logos will scorch or distort the surface.
Dry Cleaning
Do not dry clean. The harsh solvents used in commercial dry cleaning strip the natural lanolin from Merino and degrade the TENCEL™ Lyocell and elastane structure, leaving the top brittle and prone to losing stretch recovery.
Storage
Fold and store in a cool, dry place between sessions. Hanging an activewear knit long-term can stretch the shoulder seams and the mock neck out of shape; folding preserves the slim fit and the four-way stretch recovery across a full training season.
