Portwest long-sleeved thermal crewneck with merino wool

Portwest long-sleeved thermal base layer top with merino wool

This long-sleeved thermal base layer top from Portwest is made from a blend of wool and polyester and works as a close-fitting layer under your workwear. The story often begins the moment you start to warm up while still needing to keep your body dry – here, the fabric helps absorb moisture while remaining comfortable against the skin.

The thermal top is temperature-regulating and breathable, helping to maintain more consistent comfort as your activity level changes throughout the day. Its antibacterial and odour-inhibiting properties help keep the feel fresh, and the dirt-repellent surface makes it practical when conditions aren’t perfectly clean.

The model features a crew neck, long sleeves and flatlock seams for a smooth finish that can reduce irritation during movement. As a merino wool base layer, it suits anyone looking for a functional first layer with a focus on regulation, moisture management and comfort.
