Dainese Thermo LS Men's Long-Sleeve Base Layer | Thermal Underwear Top

Engineered in Italy and built on Dainese's decades of rider-focused design heritage, the Thermo LS long-sleeve base layer is the cold-weather foundation every serious motorcyclist needs. Rated for temperatures from -20°C to 10°C, it pairs advanced Dryarn® fibre technology with a seamless construction that moves with you from the first cold-morning kickstart to the last winter mile.

Key Features

• Dryarn® fibre construction (85% Dryarn®, 10% polyamide, 5% elastane) stores body heat and wicks sweat away simultaneously, keeping you warm and dry across a wide temperature range
• Seamless build eliminates pressure points and friction — particularly important under a riding jacket where seams would otherwise chafe over long distances
• Press Structure technology provides light muscle compression, reducing fatigue on extended rides and supporting circulation in cold conditions
• Armor Pad technology at key contact zones adds a discreet layer of cushioning exactly where riding position creates sustained pressure
• Tear-resistant, anti-pilling fabric holds its shape and surface quality wash after wash, preserving performance season after season
• Two-year manufacturer warranty reflects Dainese's confidence in Italian craftsmanship and material quality

Italian Heritage, Rider-First Design

Dainese has been refining motorcycle-specific garments since 1972, and the Thermo LS carries that legacy into its every detail. The fabric blend is not a generic thermal knit but a purpose-selected combination chosen for the demands of sitting in a cold airstream. Dryarn® — the world's lightest polypropylene microfibre — offers a thermal efficiency that outpaces standard polyester or wool alternatives while remaining feather-light against the skin. The finish is clean and understated, sitting flush beneath any base or mid-layer without bunching or binding.

Performance in Cold Conditions

The rated temperature window of -20°C to 10°C covers the full spectrum of cold-season riding, from sub-zero commutes to brisk autumn touring. Moisture management is integral to that warmth: where a saturated base layer rapidly chills the body, the Dryarn® construction pulls perspiration away from the skin and disperses it outward, so the insulating air pocket closest to your body stays dry. The light compression from the Press Structure panels also helps maintain blood flow to extremities — a practical advantage when ambient temperatures drop sharply.

Fitment & Compatibility

The Dainese Thermo LS is designed for men and is intended to be worn as a first-layer thermal top beneath motorcycle jackets, suits, or mid-layers. It is compatible with Dainese's own jacket and suit range as well as any third-party riding jacket where a slim-fitting thermal base layer is required. Available in sizes XS/S, M, L, and XL/XXL.
