A high-performance base layer for year-round use, maximizing the advantages of wool and synthetic fibers
The comfort of natural wool and the quick-drying properties of synthetic fibers. An ideal hybrid wear for enjoying the mountains all year round.
This is a standard long-sleeve shirt made from "Axio Lite," a hybrid wool material uniquely tuned by Teton Bros.
Wear it as activewear by itself to block the sun in high altitudes during summer. In the colder autumn and winter, it can be used as a mid-layer or base layer. While offering the soft feel, moisture-regulating properties, and natural odor control unique to wool, it also combines the remarkable quick-drying properties and durability that are the strengths of polyester. This versatile wear is a must-have for any environment, from trail running to mountaineering and multi-day treks.
Functional details directly linked to activity
Designed to prevent backpack chafing and allow free arm movement
Assuming long hours of trekking and running, the shoulder seams are offset to the front. This prevents the backpack's shoulder harnesses from overlapping with the seams, effectively reducing chafing and discomfort caused by load. Furthermore, dedicated panels on both sides expand the range of motion, allowing for flexible movement during dynamic arm swings and climbing maneuvers.
"M Stitch" to minimize skin stress
As a base layer that directly touches the skin, thorough attention has been paid to the stitching. A special "M stitch," also used in underwear, is adopted. The fabric seams have very few irregularities, which helps reduce discomfort from chafing and skin damage even during prolonged wear when sweating.
Uniquely developed hybrid material
The secret of Teton Bros. original "Axio Lite"
The base material, "Axio," is a special yarn developed in Bishu, a global wool production region. By wrapping wool fibers around a polyester core with a unique cross-section, the surface maintains the feel and functions of pure wool (moisture regulation, insulation, odor control), while the polyester core rapidly wicks away and disperses sweat.
"Axio Lite," used in this product, is a fabric created by alternately knitting this original Axio yarn and polyester yarn in a striped pattern. This achieves even higher diffusivity and stretchability than single-material fabrics. Furthermore, the unevenness of the stripes refracts light, making it less transparent despite being thin, and provides excellent breathability and anti-pilling performance.

Care Instructions
To maintain the original performance of the wool for a long time, please pay close attention to care.
-
Hand washing recommended: Hand wash in water below 30℃ with a neutral detergent, gently pressing the entire garment without rubbing or scrubbing vigorously. (Temperatures above 30℃ can cause shrinking or damage to the fabric.)
-
Short wash cycle: Aim for a total wash and rinse time of 3-5 minutes. (Prolonged immersion in water can cause fibers to harden and felt.)
-
Prohibited: Absolutely avoid using fabric softener or bleach, tumble drying, and dry cleaning.
-
Spin dry and air dry: After washing, gently remove excess water by wrapping the garment in a towel, reshape it, and lay it flat to dry in a cool, well-ventilated, shaded area. Do not leave it wet with water or sweat for extended periods.
