The Navas Mac 2.0 Crew Long-Sleeve Shirt is designed to be the optimal general wear shirt for tall guys. It’s perfectly subtle, so you can wear it on its own or layered. The stretchy, fitted and smooth bamboo is super breathable, perfect for any weather and works as an underlayer for colder days. What's different from previous versions? Same great fit now in new colours and a different external branding tag.
