Men's Active Short Sleeve

Work up a sweat without skimping on comfort with our Men’s Active Short Sleeve. Crafted with the odor resistance, moisture management, and temperature regulation properties of Merino with the durability of recycled polyester. The relaxed fit means there’s no additional bulk, with offset shoulder and side seams designed to help increase comfort and minimize chafing, no matter how you move. This short sleeve is complete with reflective elements.

Merino + Recycled Polyester Blend
56% Merino Wool, 44% Recycled Polyester. The Merino delivers the natural odor resistance, moisture management, and temperature regulation that make the tee wearable across back-to-back training days; the recycled polyester adds the durability and faster dry time a high-output tee needs. The blend breathes, wicks, and resists odor naturally — without the clammy feel a pure synthetic develops mid-workout.
Athletic Fit — Body-Skimming, Not Boxy
Our athletic fit is intended to be body-skimming to help keep the body moving freely. Cut closer to the torso than the relaxed-fit everyday tee, but with enough room through the chest and shoulders that the fabric doesn’t pull or restrict on overhead movement. Layers cleanly under a hoodie or jacket without bunching; wears on its own without looking like compression gear.
Offset Shoulder & Side Seams
Shoulder seams are rolled forward off the high-friction shoulder point, and side seams are offset from the natural underarm line — both designed to help increase comfort and minimize chafing no matter how you move. The offset shoulder is critical under a pack: a traditional shoulder seam sits exactly where a hydration-strap or pack-strap sits, creating a hot spot the second you start moving. The offset position takes the seam off the pressure zone entirely.
Reflective Elements For Low-Light Visibility
Reflective elements are integrated into the tee for low-light visibility — on early-morning runs, late-evening commutes, and shoulder-season trail starts. The reflective accents are subtle in daylight but catch headlights and streetlights at distance, adding a safety beat without turning the tee into a high-visibility piece.
Natural Odor Resistance Across Multi-Day Wear
Merino’s natural odor resistance lets the same tee cover multiple training days between washes — a 56% Merino blend keeps the fiber’s antimicrobial properties intact while the recycled polyester speeds up dry time between sessions. Less laundry, longer fabric life, and the tee stays wearable on the third or fourth day of a trip when a pure synthetic would have hit the wash already.
Moisture Management & Temperature Regulation
The Merino + recycled polyester blend manages moisture through the high-output part of a workout — Merino pulls vapor away from the skin, recycled polyester moves it to the fabric surface to dry. Temperature regulation follows from the blend: the fabric breathes when the body heats up and insulates when the body cools down, which is why this tee works across cool-morning runs, midday gym sessions, and shoulder-season hikes without an outer layer.
Training & Activewear Versatility
Built for the wide range of training and active days — gym workouts, HIIT, threshold running, cycling, trail sessions, and the everyday active wear that doesn’t quite qualify as base layer but still needs Merino-level performance. The athletic fit and breathable blend handle the output swings without the clammy chill a synthetic would develop, and the tee wears as a standalone on warm days or as a layer under a hoodie or shell when the temperature drops.

Washing
Machine wash cold on a gentle cycle. Wash with like colors — the Merino + recycled polyester blend benefits from isolated washing to protect the fabric’s moisture-wicking and odor-resistant properties. Cold water protects the Merino fibers and the recycled-polyester yarn structure. Use a mild, technical wash; avoid fabric softeners, which coat the Merino fibers and reduce their natural odor resistance.
Drying
Tumble dry low. The Merino + recycled polyester blend benefits from low tumble heat to re-loft the fabric; high heat can shrink the Merino fibers and damage the recycled-polyester yarn structure. Remove promptly from the dryer to minimize wrinkling.
Bleach & Iron
Do not bleach. Cool iron as needed — do not iron decorations. Bleach breaks down Merino wool fibers and degrades the recycled-polyester yarn. Iron only on low heat and only on the non-decorated fabric areas; high heat can scorch the Merino blend and damage the reflective elements integrated into the tee.
Dry Cleaning
Do not dry clean. The harsh solvents used in commercial dry cleaning strip the natural lanolin from Merino and degrade the recycled-polyester yarn — both of which are core to the fabric’s moisture and odor-resistant performance.
Storage
Store folded in a dry, breathable space. Merino’s natural odor resistance lets the tee cover multiple wear days between washes — folded storage preserves the fabric’s loft and the offset shoulder-seam structure; hanging for long periods can stretch the neckline and shoulder out of shape.
