This is a really useful t-shirt to have in your outdoor arsenal for all year round use. First of all, it's an ideal summer technical top with a UPF sun protection factor of 40+, it's light and very good at wicking moisture away from the body. The permanent Polygiene Odour Control Technology built into the fabric means that no matter how hard you work, you will stay smelling fresh at the end of the days activities. It also works really well on cooler days as a functional base layer garment under a fleece or down jacket. The flat locked seams mean less chance of abrasion next to the skin, especially when carrying a heavy pack. Available in men's and ladies fit.
