Our Bamboo tee is a single knit 155 gsm blend of 70% bamboo viscose, 30% organic cotton. Featuring tape bound shoulder and collar seams, for comfort and durability with twin needle stitching on the hem and arm. Water based inks are used for all print, including care label inside neck for softness and comfort. Warm in winter, cool in summer and soft next to skin. Bamboos natural antibacterial properties also mean it can be worn more and washed less. It is light enough for summer and works great for layering when cold. Finally, each tee is packaged with a small packet of bamboo seeds Fargesia Yunnanenis (clumping i.e. non-spreading variety) which if planted, could help to start to offset your purchase today.
