XTM Men's Merino 230 Long Sleeve Thermal Top

The XTM Alpine230 Men's Merino Long Sleeve Thermal Top is a crew neck base layer in 100% fine Australian merino wool at 230 gsm. XTM makes it to work as a thermo-regulator, keeping you cool when it is warm and warm when it is cold, and describes it as odour resistant, very breathable and non-itch.

Who it's for

This is the layer you put on first and take off last. XTM pitches the 230 gsm weight as a thermal base layer that regulates temperature in both directions, so it is not just for cold days - warm enough when the temperature drops, breathable enough that you are not stripping it off the moment the sun comes out.

XTM also describes it as odour repellent.

Fit and layering

A crew neck with raglan sleeves and thumb loops at the cuffs, made to be worn next to skin as the first layer. Sizes run S to 3XL in Black, Kalamata and Mid Grey Marle.

Fabric and construction

100% fine Australian merino at 230 gsm. XTM's case for wool here is that it works as a thermo-regulator rather than just an insulator, and that the fine fibre gives a soft, non-itch feel against the skin.
