These longsleeve henley neck thermal shirts are sewn with The Flat Head's original thermal fabric, which is woven using a vertical mesh knit that is similar to a vertical honeycomb thermal knit, so it has plenty of inherent stretch, recovery, and moisture wicking functionality, while keeping you insulated by trapping a layer of air against your skin. By combining natural cotton fibers with a complex mesh knit the fabric is given all of its aforementioned functionality, but it is also given a soft, comfortable hand that makes this an excellent choice for a base layer. In addition, the vertical knit ensures that the fabric will stretch horizontally when under tension, but it will not stretch vertically or misshape the hem. Finished with triple needle reinforcement at the neck to hold its shape, four-needle flat-seam stitched seams to avoid raised seams, and Japanese urea cat's eye buttons at the neck.
