Looking for an ordinary shirt that can keep up with all of your adventures? The year-round Men's Merino Short Sleeve Tee is up to the challenge. With our Core Spun technology, we've wrapped Merino around a nylon core for added durability while still keeping the comfort of ultra-soft, responsibly sourced Merino next to skin. Built for consistent comfort, even when wearing a pack, this shirt is ready to explore the world on your back.
Core Spun Technology — Merino Wrapped Nylon Core
Our lightweight Merino jersey fabric uses a recycled nylon core while still keeping 100% Merino wool next to skin. Core Spun technology wraps the Merino fiber around a recycled nylon core rather than blending the two — the result is a fabric that has the durability and shape retention of a nylon-core yarn with the soft, moisture-managing, odor-resistant hand-feel of pure Merino against the skin. The nylon core extends the fabric's lifespan past what a 100% Merino jersey would survive through daily wear and repeated washing; the Merino wrap delivers the natural temperature regulation and odor resistance that pure synthetic can't match.
Lightweight — Year-Round Standalone Tee
Lightweight jersey knit positions this tee as a year-round standalone piece — the right weight to wear alone in warm-to-cool weather, or as a next-to-skin layer under a flannel, a fleece, or a shell in shoulder-season cold. Not a base layer; not a heavy tee. The right weight for travel, day hikes, casual wear, and active use where a heavy cotton tee would overheat and a base layer would be overkill.
Slim Fit For Pack Or Solo Wear
Our slim fit is intended to follow the contours of the body without excess bulk. Engineered in men's proportions — broader through the shoulder and chest, with a sleeve length that hits the right spot on the upper arm without binding or riding up. Wears cleanly on its own for travel and casual wear without the boxy cut a unisex tee would create; layers cleanly under a flannel or a fleece without the bunching a boxier tee would create under a mid-layer.
Built For Pack Comfort
Built for consistent comfort, even when wearing a pack — the slim fit and the lightweight jersey knit handle the pack-strap load without the binding or hot-spot development a looser tee would create. The flatlock seams lie smoothly under a pack's shoulder strap and hip belt; the lightweight Merino manages the back-sweat a pack generates without the clammy chill a pure synthetic would develop when the pack comes off at a rest stop.
Flatlock Seam Construction
Flatlock seam construction designed to help increase comfort and minimize chafing — the seams are sewn flat rather than raised, so they don't dig into the skin or create friction hot spots under a pack strap, a harness, or a mid-layer. The flatlock construction matters most on a tee that gets worn day after day across travel days and multi-day trips where chafing would end the comfort.
Merino Moisture & Odor Management
100% Merino wool next to skin delivers natural sweat management, odor-resistance, and temperature regulation — the natural Merino fiber pulls moisture vapor away from the skin before it becomes visible sweat, resists odor-causing bacteria across multi-day trips, and regulates body temperature across the wide range of conditions a year-round tee sees. The lightweight jersey breathes well in warm weather and insulates adequately under a mid-layer in shoulder-season cold.
Recycled Nylon Core — Lower-Impact Durability
The recycled nylon core delivers the durability and shape retention a daily-wear tee needs to survive repeated wearing and washing, with a lower-impact material choice than virgin nylon. The recycled content doesn't compromise the fabric's performance — the Core Spun construction gives the same abrasion resistance and recovery as virgin nylon core, with less reliance on new petrochemical feedstock.
Year-Round Versatility
Built for the year-round uses where a lightweight Merino tee is the right tool — travel days, day hikes, casual wear, warm-weather hiking, summer backpacking, fall trail running, shoulder-season layering under a flannel, and après-activity wear. The lightweight jersey handles the wide range of conditions across a full year without the overheat a heavyweight would develop in summer or the chill a pure synthetic would develop when the temperature drops. The Merino content stays fresh across multi-day trips; the flatlock seams stay comfortable under load.

Washing
Machine wash warm on a gentle cycle. Wash with like colors — the Core Spun Merino-recycled nylon blend benefits from isolated washing to protect the fabric's moisture-management properties and the flatlock seams. Warm water is allowed on this lightweight jersey (warmer than the cold-only spec on heavyweight base layers) because the lightweight knit tolerates the warmer wash that helps release body oils and sweat from a daily-wear piece. Use a mild, technical wash; avoid fabric softeners (they coat the Merino fibers and reduce natural moisture management).
Drying
Tumble dry low. The lightweight jersey knit and the Core Spun construction tolerate low-heat tumble drying without distorting the fabric's structure — low heat restores the loft of the Merino fibers and the recovery of the recycled nylon core. Do not tumble dry on medium or high heat; high heat can shrink the Merino fibers and degrade the flatlock seams.
Bleach & Iron
Do not bleach. Cool iron as needed — do not iron decoration. Bleach breaks down Merino wool fibers and degrades the recycled nylon core's strength. Iron only on low heat and only on the non-decorated fabric areas; high heat can scorch the lightweight Merino jersey and damage the flatlock seams.
Dry Cleaning
Do not dry clean. The harsh solvents used in commercial dry cleaning strip the natural lanolin from Merino and degrade the recycled nylon core's integrity — both of which are core to the fabric's performance.
Storage
Store folded in a dry, breathable space. Merino's natural odor resistance means the same tee covers multiple wear days between washes, which extends the fabric's lifespan and makes this a true year-round travel piece rather than a single-trip item. Folded storage preserves the flatlock seams; hanging for long periods can stretch the lightweight jersey out at the shoulder.
