finetrack Dry Layer Basic Long Sleeve (MEN'S)

A first layer that lifts sweat away from your skin, cutting down on sweat chill and stickiness

Dry Layer Basic Long Sleeve (Men's) is a thin base layer worn directly against bare skin. A water-repellent mesh on the skin side resists holding onto moisture, moving sweat quickly to the moisture-wicking, quick-dry layer worn over it, which cuts down on the chill and stickiness that follow activity. Across mountaineering, trekking, and outdoor activities of all kinds, it's a foundation for anyone who wants to stay comfortable through a sweat, whatever the season.

The all-season balance of the BASIC line

The Basic series balances a moderate level of insulation with sweat clearance, in a build that doesn't limit which activities it suits. It resists holding sweat against the skin in hot weather, and in cold weather it eases the chill that comes from moisture coming back. It's an easy-to-choose standard line for a first Dry Layer. The long-sleeve cut layers easily under a long-sleeve base layer, covering you from the torso to the wrists. Comes in Black.

How the skin-side water-repellent mesh works

The fabric against your skin is a water-repellent polyester knit mesh. The fibers themselves resist holding onto water, and countless pores drive a capillary action that smoothly moves sweat to the moisture-wicking, quick-dry layer worn over it. Because the structure limits moisture coming back to the skin side, it eases the discomfort of sweat clinging to your skin and the sudden chill that can hit during a break or when the wind picks up.

Durable water repellency (100 washes, 80 points) and antibacterial odor control

The fiber's water repellency lasts: it keeps a water-repellency rating of 80 points even after 150 washes. It also carries an antibacterial odor-control finish, confirmed at a 99.9%+ inhibition rate under JIS L1902 (bacterial solution absorption method, using Staphylococcus aureus). It still clears the standard after 150 washes (it doesn't inhibit all bacteria). Its dryness performance lasts about 1.5 times longer than the previous Skin Mesh.

A soft feel and stretch that follows your movement

A stretchy knit mesh fits gently against your body. Seams are kept away from the skin in key spots throughout, and the thin, lightweight build keeps it from becoming a source of stress through long hours of activity. Generous stretch doesn't get in the way of movement, following you through raising your arms or big shoulder motions.

What the long sleeve brings to how you use it

The classic long-sleeve cut that covers your arms layers under a long-sleeve base layer without adding bulk, building a sweat-clearing layer all the way to your wrists. It's an easy shape to work with not just for long hours of activity like mountaineering and trekking, but also in situations where how much you sweat or the outside temperature keeps changing.

Layering it right, and choosing your size

The way to bring out its effect is simple. Wear this Dry Layer directly against your skin (with no other base layer in between), then layer moisture-wicking, quick-dry clothing over it. The ideal size is one that follows your body without gaps, while staying short of too tight. The closer it sits to your skin, the easier it moves sweat outward, and the more it holds down moisture coming back.

Ongoing refinement and recognition

The spring 2020 renewal added antibacterial odor control on top of improved durable water repellency. Dry Layer also won the 2026 Good Design Award, and as a standard base layer piece with more than 20 years behind it, it's also backed by professionals in the field, including rescue teams. Built on Japanese manufacturing, it keeps refining what matters most in base-layer sweat management. The judging praised its clear function of "keeping skin dry at all times" and its pioneering role in opening up this category over more than 20 years. Alongside the reliability it has earned through professional use, its commitment to supporting Japan's own manufacturers also drew appreciation.
