Woolpowers 200g fabric is durable and made from fine merino wool, polyamide and most of all – air!
 
The air in the Base Layer fabric is important as it isolates the heat that your body produces.
Best & most effective when worn directly against the skin. Excellent insulating and wicking properties.
 
Long sleeve turtleneck has a short zipper for ventilation
Made of circular knit fabric, and has no lengthwise seams.
The back is longer to prevent gaps. Cuffs are knitted in.
 
**Other sizes available by request**
