The flannel shirt is crafted from 100% heavyweight cotton at 320 GSM, featuring a classic button closure and flap chest pockets for practical everyday wear. The coordinating thermal top is made from a 60% cotton and 40% polyester blend at 183 GSM, with ribbed cuffs for a comfortable, secure fit. Both pieces are made in Bangladesh and available in Black, Navy, and Red colorways in sizes M to XXL.
