A high-performance hybrid-wool sleeveless top that never gets in the way of your arms
Eliminating shoulder stress. Ultra-thin hybrid wool that supports high-intensity midsummer activity.
A men's sleeveless shirt in Teton Bros.' own tuned hybrid-wool fabric, "Axio Lite."
In high-intensity activities where you swing your arms hard—trail running, steep summer climbs—freedom around the shoulders directly affects performance. This model follows the lines of the body while being cut as a sleeveless shape that never restricts arm movement. A hybrid material that multiplies wool's moisture regulation and odor control with polyester's overwhelming sweat-wicking, quick-drying power keeps you dry and comfortable even on midsummer fields where you sweat heavily.
Functional details that connect straight to your activity
A dedicated design that doesn't interfere with arm movement
The armhole shape is worked out so it never interferes with big shoulder and arm movements or a dynamic arm swing. There's no fabric strain, so you feel no stress during long runs or climbing.
Offset seams and M-stitching that prevent pack rub
The shoulder seams are offset toward the front, so they don't overlap with a pack's shoulder harness, effectively reducing rub and pain from the load. It also uses a special low-bulk "M-stitch" found in underwear, leaving flat seams that curb skin damage during long wear while sweating.
An in-house hybrid material
The secret of Teton Bros.' original "Axio Lite"
The base yarn, "Axio," is a special thread born in Bishu, a world-renowned wool-producing region. By wrapping wool fibers around a shaped-cross-section polyester core, the surface keeps the full hand of wool along with moisture regulation, warmth, and odor control, while the polyester core wicks sweat up quickly and spreads it out.
The "Axio Lite" used here is a fabric that alternately knits this original Axio yarn and polyester yarn in stripes. This gives it even higher moisture dispersion and stretch than a single material. The texture of the stripes also refracts light, so despite being lightweight it resists see-through, combining high breathability with anti-pilling performance.

Care
To keep wool performing at its best for a long time, please take care with washing.
- Hand wash recommended: Use a neutral detergent in water below 30°C, and hand wash by gently pressing the whole garment—do not knead or scrub hard. Water above 30°C can cause shrinkage and damage.
- Keep it short: Aim to finish washing and rinsing within 3–5 minutes total. Soaking for long periods causes the fibers to mat and felt.
- Do not: Never use fabric softener or bleach, tumble dry, or dry clean.
- Spin-dry and drying: After washing, wrap in a towel to gently remove water, reshape, and dry flat in the shade in a well-ventilated place. Do not leave it wet with water or sweat for long periods.
