Musto HPX Merino Baselayer Long Sleeve Top

Musto HPX Merino Thermal Baselayer Long Sleeve Top

The Musto HPX Merino Thermal Base Layer Long Sleeve Top is designed for sailors operating in extreme offshore and cold-weather environments. Made from premium ZQ-certified Merino wool with reinforced CORDURA® elbow panels, it delivers natural warmth, moisture management, odor resistance, and unrestricted comfort for long days on the water.

Engineered for demanding offshore conditions and technical layering systems, the Musto HPX Merino Thermal Base Layer Long Sleeve Top combines the natural performance of Merino wool with enhanced durability for extended use in harsh environments.

Constructed from premium ZQ-certified Merino wool, this thermal baselayer naturally regulates body temperature while efficiently wicking moisture away from the skin to keep you warm, dry, and comfortable through changing conditions. The fabric’s natural odor-resistant properties make it ideal for multi-day offshore passages and high-output activity.

The layered 4-way stretch construction provides unrestricted movement while sailing, trimming, or manoeuvring on deck, ensuring comfort without restriction. Reinforced CORDURA® fabric panels on the elbows increase durability in high-wear areas, helping the garment withstand repeated use in demanding marine environments.

Designed with a crew neck profile and seamless side construction for reduced chafe and enhanced next-to-skin comfort, this baselayer integrates easily under technical mid-layers and outer shells. Whether racing offshore, cruising in cold conditions, or adventuring in alpine environments, the HPX Merino Thermal Base Layer Top delivers dependable warmth and technical performance.
