Long-sleeved, thermoregulating baselayer with sweat-wicking properties to stay extra warm and dry all year round

Coming in hot to complete our baselayer range, the 3D Thermo HZ Top is your essential ally when the temperature hits rock bottom – and beyond. Warmer and thicker than our 50g and 110g models, this undershirt offers the same high-performance, thermoregulating technologies with specific body-mapping for added warmth in sensitive areas. Worn against the skin, the 3D weave not only evacuates sweat, it also creates an air mattress to retain heat sweat and ensure your core temperature stays stable in all situations. The stretchy, seamless design is durable and comfortable, fitting ergonomically to any body shape with zero irritation. The postural knit in the back helps you keep your shoulders straight as the hours build up, while the fitted Raglan sleeves offer localised compression for extra support and freshness on the biceps and forearms. Pull up the extra high collar for protection in chilly gusts and snow or open the auto-locking zip for welcome ventilation when the intensity ramps up. Combining high tech versatility with optimal protection, this functional thermoregulating baselayer is ideal under a jacket or gilet on your next trail running, ski touring or midwinter cycling challenge. Not limited to freezing cold outings, it can also be worn as a solo layer in milder climates.
