Heatrub Merino Wool Baselayer

The new super soft Heatrub Merino Wool Baselayer is Zerofit’s most luxurious product, offering the benefit of incredible warmth but with a more gentle feel against the skin than the Zerofit Heatrub Ultimate Baselayer. Although the CLo rating (warmth retention figure) is lower than the Ultimate, the Merino Wool is still three times warmer than a standard baselayer and is ideal for a number of activities including golf, hiking, fishing, sailing and spectator sports.

The high wool content (75%) and super soft feeling of the inside of the garment gives the user a warm, cosy experience, with an added touch of luxury. The excellent humidity control of Merino Wool has been designed to absorb sweat and dries quickly to eliminate any potential for ‘cold sweat’.


– Luxurious, super soft feeling on the skin.

– Suitable a huge range of sports and activities in a temperature range of -10° Celsius thru 10° Celsius

– Humidity control is designed to absorb sweat and dries rapidly to eliminate potential for any ‘cold sweat’.
