DetailsAn is an ethically sourced, 100% Australian Merino wool long sleeve shirt with a ½ zip to the neck. This shirt is best suited for casual wear and as a first layer on winter days or the only layer in the spring and summer. The regular cut sleeve and flat seams enhance comfort. It is extremely soft due to the use of 16 micron diameter thread. This is the finest wool available and has a silk like feel to it. Merino wool is highly antibacterial and microbial therefore it naturally eliminates orders and can go between washes longer than other materials. It also has excellent moisture wicking properties, therefore you feel warm and dry even in extreme weather conditions.
