ltm × [sn] sleeveless base layer

The ltm × [sn] sleeveless base layer, which has been highly requested, is finally here.

Available in three uplifting colors perfect for spring and summer.

Designed to be worn true to size, this sleeveless base layer is intended for layering under mountain shirts.

By keeping the arms uncovered, it reduces heat and stuffiness around the armpits, ensuring comfort even when making large arm movements, such as on rocky ridges or steep climbs.

This is a recommended item for those who "get hot easily but still want to wear long sleeves" or "want to wear vests and mountain shirts more comfortably."

This time, it's available up to XXL size to accommodate more people.

We encourage even those who haven't had the chance to wear ltm before to try this finished product.

Fabric and Material

Wool 50% / Polyester 50%

Australian Merino Wool

We use rare Australian Merino wool, which accounts for only about 10% of all Merino wool.

Bishu-finished Merino Wool

The final processing is done in Bishu, Japan, known as one of the world's three major wool production areas. By using soft water, the fabric is finished with a smooth texture and natural luster.

Compact Spun Yarn

By using yarn that suppresses fuzzing, it resists pilling and offers durability for long-term wear.

Exquisite 143g/㎡ Thickness

While general wool base layers are around 150g/㎡, this product is 143g/㎡.

By making it slightly thinner, it achieves an exquisite balance that enhances breathability and lightness while reducing transparency.

Furthermore, by blending 50% polyester, it also ensures quick-drying properties and durability.

This is a versatile item that can be used not only in spring and summer but throughout the year.

Silhouette

Unlike common loose-fitting sleeveless T-shirts, this item is designed to fit true to size to function as an inner layer for mountain shirts and shells.

By moderately conforming to the body, it enhances sweat absorption and quick-drying properties, supporting comfort during activities.

Additionally, we have reviewed the conventional base layer size range, which used to go up to XL, and now offer up to XXL size to accommodate a wider range of body types.

Please experience the comfortable feel unique to merino wool and polyester.
